Just to let you all know I've been having problems with the car this week, went out on Wednesday to start her up.....turns over fine just didn't want to fire.

Did the ususl, called RAC who sent a guy who was obviously knocking off as he simply spent 10 mins checking fuses (I'm not by any means a mechanic but even I'd already managed that) and turning the car over before asking where I wanted it towing.
I declined his offer but agreed I'd call back if I wanted it taking to a garage.

Yesterday was spent with a (cheap local) auto-electrician checking the ususl, fuel pump (ok) fuses (ok) when he had finished he said I had a problem with the immobiliser.

Fast forward to today and had out a (bit more expensive/not so local) auto-electrician who specialises in immobiliser faults, he came with all the gear, plugged it in and came up with the following.....

He also said that the ECM 'could not be found' (whatever that means), and said it could either be a wiring fault or the ECM could need re-flashing.

Have any of you ever had anything like this before ?

The car is now booked in to be collected by the RAC Monday at 0830 and taken to Carpenters, an Independent Volvo Specialist (est 1934) who say they should be able to tell me what's wrong by Tuesday lunchtime.

As I'm a glutton for punishment I am offering a very small and extremely cheap Volvo related prize to whoever comes up with the nearest diagnosis/cost for this to be fixed.....over to you !

It's a 1998 ME7 it's a new suggestion that the throttle body sensor could be the cause.

I had a fault many years ago the old girl wouldn`t start and called a local garage to find the fault, pluged his bit of kit and said the ECU is f##ked because he couldn`t connect to it.

So I called out a local indy volvo garage and he pin pointed the fault to the MAF which when changed the old girl started :)

I think the your indy volvo garage should pin point the problem.

Shame I couldn't be more help. I doubt it would be the throttle as there would be warning signs and it would still start.
And I'm not sure if you can play swap the ecu with ME7 as its coded to everything else in the car.

Fingers crossed tho mate, she'll be in good hands and hopefully there'll be a quick and not-top-expensive resolution.

Keep us posted mate.

if its the ECU thats at fault get a second hand one doesnt matter if its auto or manual, Volvo will reflash it with original software for £78 all in. As some one already said if it was the anything to do with the throttle you would have codes and a light dash, your ETS and ENGINE lights would be on.

Secondly, there is fuel getting in as the plugs were soaking when removed (and changed just in case). Does this point away from the immobiliser? can anyone tell me?

The reason I ask is that whilst my small OBDII code reader did not pull off a
P1670 code (only a P0300 misfire code), the code reader at the garage (Smartbox) pulled off the following two codes:

At 5;21pm - TOTAL CODES 001
IMM 321 "Initiation signal from engine control module (ECM), signal missing"

Then on a second try at 5:26 - TOTAL CODES 001
ECM-720A "Immobilizer communication"

The good news is that the mechanic wasnt convinced and said that sounded like the engine was just flooded and decided to try tow starting it - IT WORKED! after switching off it restarted with the key ok.



Now this IS interesting.....

The RAC guy asked when I last started the car and for how long I left it running, I had simply started it and turned it staright off, he also reconed it was flodded but couldnt get it going again by turning it over.....I've also heard these engines don't like being started and turned off straight away.....just gotta find someone to tow start me to find out !

This happened to me with my T4 it was flooded charged my battery right up for a day took the plugs out also for a day to dry out the cylinders and it started when all back together easily.

It`s called "Lanwmower Syndrome" ....no joke.....you move the car to get the lawmower out for the lawn then you can`t start it again when you want things all back in the garage etc.

A battery in excellent condition seems to overide the condition and it will start.

Right, latest update......(don't get excited though)

Had a call from Wayne (Judgeninja) last night and he very kindly offered to come up and have a look at the car for me this afternoon, he took out the plugs and to be honest they weren't that wet, he checked a lot of other connections but really I am no further forward, it seems as though the immobiliser is not letting the car fire, though this could also be no compression due to 'lawnmower syndrome'

Anne has told me enough is enough and not to worry/guess any more tonight, the car will be at the garage tomorrow and they can try and get it going, I am working 0900 till 2100 Mon-Thu this week, I just hope I can go pick her up (the car not Anne) on Friday in time for the 'Softies' meet on Sunday.

I hope it's a simple fix for the garage Graham, and not too expensive.

M-R-P
Sunday 4th November 2012, 20:57
Just found this on brickboard.com...

I stumbled upon a fix today that is easier to do, less stressful on the car, more environmentally correct and easier on neighbor relations that some of the methods I've read about. I'll explain below what I did and why I think it worked for me. Maybe one of the experts on this board will reply whether this makes sense or I was just lucky. Luck is often more desirable than skill.

Background: LMS is a nostart condition. It occurs after a stone cold Volvo 5 cylinder engine has been run just long enough to back the car out of the garage in order to use one' lawn mower (30 seconds or so). The theory is that the car's computer commands a rich fuel mixture when the engine is cold. When the cold engine is turned off, the gasoline from the rich fuel mixture dilutes the oil that helps form a tight seal between the piston rings and the cylinder wall. The result is insufficient compression for the engine to start.

My son's '98 S70 developed LMS after he cranked it cold and moved it to the other side of the driveway so his car no longer blocked my Saab 9000. LMS was discovered the next day when his car wouldn't start. The car has 111K miles and no previous LMS problems. I fixed it 3 days later after doing enough research to decide that LMS was the likely problem.

Here's how:
1. Press the gas pedal to the floor. Keep it there while doing step 2.
2. Crank the engine for 30 seconds, which is long enough for the oil pressure idiot light to turn off (the ambient temp was about 70 degrees when I did this). Cranking 30 seconds pumps motor oil through the engine. But the oil needs a few minutes to do its piston ring magic.
3. Wait 15 minutes. I waited to let the starter motor cool, and only realized after the fact that waiting allowed the oil to fix the compression problem.
4. Press the pedal to the floor and crank. I did this thinking I would crank another 30 seconds before letting the starter motor cool again. To my surprise and delight it fired up almost immediately on all cylinders.
5. Back off the throttle and let it run a minute or so at 2,000 rpm. It idled normally after that. This step may not be necessary, but I wanted to be sure the engine wouldn't die.
6. Go for a short drive to warm up the engine before turning it off. Then restart it for the sake of your peace of mind. I drove until the temperature gauge rose to about 3 o'clock.

If Graham`s car has LMS then pouring a small amount of oil down the spark plug holes would bring the compression up and the car would start.

As I`m off to Gothenberg in the small hours of the morning for a few days keep me posted on the outcome :wink:

Monday 5th November 2012, 00:31
Interesting, in all my years of moving my 850 I've never had this syndrome.. Or even until this evening I had never read how to correct the issue.

We did give the car a bit of stick to try to get it to fire, and the engine did seem to be turning over quite fast, but there was no smell of fuel on the two spark plugs we removed. As a result we sort of determined that possibly the injectors and spark plugs were not firing. I have one of those sparking units that sits on top of a spark plug earthed using a screw driver.

I'll be watching the final prognosis with interest..

I am not a one for hanging on a starter with a modern motor as if our cars don`t start quick there is something wrong, with my T4 the plugs were soaking wet when taken out and so were the combustion chambers, the reason i let to dry out all day was the fact that holding open the throttle is suppose to do the opposite of an N/A engine with a carburretor.

If flooded on a carb. unit you open the throttle WOT and let more air in to dilute the petrol to start but with an ECU and MAF engine the MAF will say put more petrol in as the throttle is WOT so you should not open the throttle.

It says this in the handbook...don`t touch the throttle when starting... it is very difficult not to as we are creatures of habit so i always keep away from it and have no trouble starting since even on my V70 T5. But now i have two batteries, a new one and another always fully charged just in case.

These modern motors are very battery reliant with all the gismo`s and sensors etc. and i remember with my GDI once i arrived home and the dash lights all started flashing like christmas trees and wondered what the hell was happening. I wound up the electric window and the engine stopped while doing so. Tried to start it but battery knackered. The alternator had packed up just like that.

The joy`s of motoring.

Right, I'm home.....

Car was collected at 0900 this morning and taken to the garage, around 1430 I had a phone call.

They had checked for flooding and found no sign this was my problem, the compression was good, so they plugged in the code reader and found the 'ECM not found' code which I had been told about previously.

They suggested flashing the ECM I had, cheapest option, and so thats what they did.....no luck.

They are now 99% sure it is the actual ECM, and they have given me 2 choices, as they do not have and cannot source a reconditioned unit I can either send mine away to be tested and possibly fixed (approx 2 weeks) at a cost of £400.00 or go for a new unit from Volvo at £700.00 :yikes:

Obviously whichever way I go I will need to flash the new unit as well.

BUT.....take a look at this (last post)

http://volvoforums.com/forum/volvo-v70-13/motor-spins-will-not-start-55375/

NOW what should I do ? Also where would I stand if I gave them the go ahead and it turned out not to resolve the problem ?

If there's no communication to the ECM, it's the ECM itself.
I've repaired a few units for a small fee but I'm a great distance from you guys, so that's out of the equation.
You can take a CEM, ECM and the car keys from a donor (scrapped) vehicle of the same year and make and use them though.

But now i have two batteries, a new one and another always fully charged just in case.


In my experience this is not always the case. I forget which make but some of the cars out there are actually programmed to switch off the injectors when WOT, if the engine is not actually running. This can be advantagious when a car engine is flooded because it prevents further fuel being injected.

I too have never heard of the 'Lawnmower effect'. In the trade, a car that is flooded with fuel and doesn't start is commonly known as being 'borewashed'. Anyway...as far a Graham's V70 is concerned, i would be checking the following:

1: Battery voltage above 12.2v and cranks the engine
2: Check for 12v and 5v references at injectors / MAF (this will rule out ECU fault/if 5v is present then the ECU is powered up and working)
3: Injectors switching on crank? (This will eliminate ECU, crankshaft sensor fault and immobilisor)
4: Fuel pump current draw? (check at the fuse - should be between 5 - 8amps)

If i found the above to be all present and correct and the car does not start, then as far as i'm concerned the car is flooded as Graham has already admitted to starting and switching off the car in a very short time.

You do not need to pour oil into cylinders to irradicate this issue. Simply remove the spark plugs then clean and dry. Then with car battery connected to either a powerful boost pack/doner car with good jump leads that can carry 200AMPS without melting or a battery charger that has a boost start facility, crank the engine over for no more than 10 seconds each time with a minute inbetween to cool down. This will irradicate the borewash and prevent overheating the starter motor. You only need do this a few times. Refit the spark plugs, refit the fuel pump fuse then crank her over (without touching the throttle). Car should start.

I find it very hard to believe that the dealer are pinning this down to a faulty ecu. (BTW, ECM and ECU in Volvo speak are the same thing. Engine control Module or Unit are both the same thing).

If the RAC man did his job properly, the above 4 checks take no more than 15 minutes. Tools needed are a Multi meter and a Noid light or LED tester for switching at the injectors and an AMP clamp.

Just throwing this out there, but nobody has mentioned doing a battery reset! If any of the ECU's has had a hissy fit it stops working or freezes. SImply removing the earth off the battery for 5 minutes then refitting often cures the problem and restores everything back to normal.

Works on all makes and models (you just have to becareful when reconnecting the battery as some cars have a certain procedure ie Volvo P2 models - you MUST have the ignition ON before reconnecting the earth)

EXAMPLE: Volvo V50 2.0D, cut out halfway up the driveway after driving home from work. Car was an AUTO and was also stuck in D. After a minute the customer managed to get the gear select into P but then it still wouldn't start. I arrived and carried out a few simple checks including checking for any fault codes, none were stored. Disconnected battery.....refitted and vehicle started. Everything restored to normal operation. Conclusion was the car's Gearbox ecu had a hissy fit causing car to cut out. The reason why the car wouldn't start was because the ECU thought it was still in D, therefore preventing the engine from starting (built in safety). After powering down the ECU and rebooting...the correct gear was selected, ie P and the car would then start. Mechanically all was well as i followed the car to the garage, just incase there was an inherent gearbox fault.

You should be asking the Dealer these Q's Graham before you shell out £700 for a new ECU!!

As far as the Diagnostic codes...They are there as an aid to diagnostics and not the Be ALL and END all to the inherent fault. It does pi@@ me off when ppl and or dealers jump to the wrong conclusion and assume that just because a diagnostics reader says: ECM - No communication, does NOT mean that your ECM if ££££ed! You need to do the basics first and always assume that its something simple.

I hope that the dealer find the fault and that it doesn't cost you dear.

Then with car battery connected to either a powerful boost pack/doner car with good jump leads that can carry 200AMPS without melting or a battery charger that has a boost start facility, crank the engine over for no more than 10 seconds each time with a minute inbetween to cool down. This will irradicate the borewash and prevent overheating the starter motor. You only need do this a few times. Refit the spark plugs, refit the fuel pump fuse then crank her over (without touching the throttle). Car should start.

I find it very hard to believe that the dealer are pinning this down to a faulty ecu. (BTW, ECM and ECU in Volvo speak are the same thing. Engine control Module or Unit are both the same thing).

If the RAC man did his job properly, the above 4 checks take no more than 15 minutes. Tools needed are a Multi meter and a Noid light or LED tester for switching at the injectors and an AMP clamp.

Just throwing this out there, but nobody has mentioned doing a battery reset! If any of the ECU's has had a hissy fit it stops working or freezes. SImply removing the earth off the battery for 5 minutes then refitting often cures the problem and restores everything back to normal.

Works on all makes and models (you just have to becareful when reconnecting the battery as some cars have a certain procedure ie Volvo P2 models - you MUST have the ignition ON before reconnecting the earth)

EXAMPLE: Volvo V50 2.0D, cut out halfway up the driveway after driving home from work. Car was an AUTO and was also stuck in D. After a minute the customer managed to get the gear select into P but then it still wouldn't start. I arrived and carried out a few simple checks including checking for any fault codes, none were stored. Disconnected battery.....refitted and vehicle started. Everything restored to normal operation. Conclusion was the car's Gearbox ecu had a hissy fit causing car to cut out. The reason why the car wouldn't start was because the ECU thought it was still in D, therefore preventing the engine from starting (built in safety). After powering down the ECU and rebooting...the correct gear was selected, ie P and the car would then start. Mechanically all was well as i followed the car to the garage, just incase there was an inherent gearbox fault.

You should be asking the Dealer these Q's Graham before you shell out £700 for a new ECU!!

As far as the Diagnostic codes...They are there as an aid to diagnostics and not the Be ALL and END all to the inherent fault. It does pi@@ me off when ppl and or dealers jump to the wrong conclusion and assume that just because a diagnostics reader says: ECM - No communication, does NOT mean that your ECM if ££££ed! You need to do the basics first and always assume that its something simple.

I hope that the dealer find the fault and that it doesn't cost you dear.

1. Battery voltace checked and over 12.2v and cranking fine.
2. NO 12v at injectors, power IS getting to ECM.
3. Injectors NOT switching on crank.
4. Fuel pump seems fine, fuel under pressure at rail.

U would expect all the basic checks done prior concluding a £700 needs replacing,wouldn`t u?Tbh I don`t know the set up of me7 so can`t really comment but all the facts indicate on ECM so lets wait and c.I know it`s a bit of money tp spend Graham but u won`t find the same one thats for sure so it`s worth it.

Just an idea it couldn't be the cam or crank senser because if they go down then the Ecu would not fire the injectors.just an idea that's all .

Normally comes up on diagnostic unless the pick up point is out of line for which it`ll be cam belt jumped over but if it cranks ok it`s not that.

2. NO 12v at injectors, power IS getting to ECM.
3. Injectors NOT switching on crank.
4. Fuel pump seems fine, fuel under pressure at rail.

If the ECM has power, ie 12v then this means that fuses 8 (60a) and fuse 10 (10a) are ok. If your fuel pump is working then this indicates that the Engine Control Relay is working via fuse 12 (20a). However, the Engine Control Relay also supplys 12v to the injectors via fuse 11 (10a). The fuel injectors on your car Graham do not get 12v from anywhere else other than Engine control relay via fuse 11 and fuse 8. This engine control Relay ALSO supplys 12v to the MAF sensor. So, if you don't have 12v at the MAF then the fault has to lie with the Engine Control Relay if fuses 8 and 11 are ok and have 12v going through them.

The main ECM has a direct 12v feed from the ignition switch at terminal A12, so if the ECM is powered up it won't tell you much.

If you don't have 12v at the injectors then you won't get a switching pulse anyway. Also, if the ECM is powered up then you should have a yellow engine management light on the dash.

You never did say, but did you have 5v at the MAF?

The fact your missing 12v at the Injectors is a good sign as far as i'm concerned and has nothing to do with the ECM.

It ended up being 2 days.....

Anne got a phone call at lunchtime to say that they had received the new ECM, flashed it with software, fitted it, and the car started with the first turn of the key :D

Yes I suppose I could have gone down the route suggested by glock19 (post #52) hunting out a car of the same year to source the CEM, ECM and keys, but even if I had done all that how long would that one have lasted ? 10 years, 1 year, 1 month ?

At the end of the day Anne and myself had a chat and deceided that as we both enjoy the car so much it was worth the outlay, we feel our car is in good condition for the year and using it, attending meets and being on the forum is something we both enjoy, added to which we have met some great people on here.....how much is that worth ?

Are we glad the car is fixed.....yes

Are we thankfull for all your posts on this thread.....yes

Are we looking forward to the 'Softies' meet on Sunday.....yes

Are we looking forward to seeing Frankie's face as I snick the car into 3rd and pull away from him in whatever car he has next year at Santa Pod.....hell yeah (ok I made that one up :o)

Thank you all for your help and suggestions, VPCUK to the rescue again.

It's true you wouldn't know what condition the donor units will be and yo might be back to square one.

Although re-manufacturing is often a good means of getting it going again, there's still no way of knowing how long the repair will last.
If the eprom chip itself had failed, there's nothing you can do but replace. I'm not 100% that this was the problem with Graham's car but if it had been sent away for a few days to repair, only to find that there was nothing that can be done for it, that's another few days of no car plus more expense. Where as, it took 2 days for a new unit to arrive and be fitted and updated with the latest Volvo software, which SHOULD last indefinitely, I would personally take the hit. (after spending £732.50 on a new DIM, I should know)
