850 t5 difficult to start when cold

[merc85]

Gav, just my 2 pence worth.....if you can't find the source of your problem, would it be such a bad idea to get a dealer to loook at it ?
Not being funny but they have all the gear and could probably at least diagnose the fault for about £50 or so, then you would at least know what you were looking at to get the car running again, might even be a cheap fix too !

Good luck with whatever you do, just think really hard before breaking.

Simply havent got the money to get a dealer to look at it, And also the closest one in 20 miles away and that means towing it.
Spent so much time money and effort on the car really cant be arsed with it. Engine ran so smooth and powerfull didnt even get to boost her hard as was runing her in.

Think the car has more wiring issues , has done in the past im not going to be changing looms as you dont know how good the next looms going tobe, pritty much decided to break her,

As soon as ive found a replacement i will know what parts will be avalible, rest assured tho peeps will be getting Good quality parts as ive always looked after my car.

Also in reply to your VOC post if this is done to immob the immobiliser part then it says it can be started!

Can`t lose anything by trying

Ok car wont start again so gonna give this a try but i dont understand, Do i remove relay 210/211 and bridge it, Then Remove the single 210? or do i just remove the relay 210/211 and bridge it? or leave it out altogether?

Ignore 211

Remove relay 210

Bridge terminals on the base plinth on the fuse box between 50E and 50F and that`s it.

Picture of Relay 210 Volvo Starter Relay Switch is a special Volvo part which the dealer uses instead of a piece of wire to
bridge the terminals.

Road Recovery vans can use this method when the owner has lost keys etc. as it bypasses the whole immob part of the ignition.

This pic. is for 1994 Manual so it should be yours unless maybe auto is different?

On the car it shows where it is as left hand drive so we are opposite side!


Don`t worry about answering as i just post things to help and maybe for you to check.
I think you will let all know when the motor works ok.

Thanks 960kg, Have tried the above and car deffo wont start, Car will now be broken once replacement has bin found as it no long starts

Dam and blast got bored tonight, so decided to investigate, retrieved cam sensor code and then cleared it, car didnt start so took the ecu out again inspected the wiring, all seems ok although the comman earth may have bin repaired at some point. after messing about with the cam sensor pins checking resistance to the ecu which all apeared ok i tried to start the car.....

Yep you guessed it she bloody started! wtf ????? any ideas????

[960kg]

Got some more pics. for you to try unless you have done them all as it says??

Some remarks are obvious to you as you know it won`t start, but at least you may find something from them.

One pic. tells you what terminals to the ECU to check from the CMP

See the earth hidden under the coil.

Good luck with that, I hope it's not that orange t5 on flea bay as I spoke to him yesterday and within a 3 minute conversation he changed his mind 3 times about things and mods.... And I can't get a HPI report for it.

Im going to throw a wild one out there but worth a blast if nothing else.

I remember there being a common fault with the fuel pump relay in the 850's which as described caused starting problems until at one point the relay clicked and switched over and the car would start... it was a problem I had on the T5-R so I changed the relay and it solved the problem.
