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.
A big thank you to everyone who has contributed to this thred so far, it's not nice having a sick Volvo
M-R-P thanks for keeping my spirits up with texts, and Wayne I hope I have to give you a £1 next sunday, thankx mate.

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

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

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..

Fliipinheck Graham sorry to read this lot
I Can't offer any advise other than what has already been tried.....Here's hoping for a wallet friendly outcome.

i had a similar problem with mine...
it was the immobiliser control box that sits on the clocks under the top dash.

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.
Any news....?
