01 2.0 TS - recent cold starting concerns - DP
The last couple of mornings, the Volvo has exhibited behaviour that is a mite concerning. Yesterday morning, it fired up instantly as normal, but wasn't running on a full compliment of 5 cylinders. A quick blip of the throttle cured it, and it's been fine ever since. This morning, it didn't want to start at all. It took about 20 seconds of cranking before it fired up (after which it ran perfectly).

Any suggestions? The spark plugs are genuine Volvo items fitted by a main dealer at the last service they were due, and are still well within their service life according to the schedule. I would normally be checking things like HT leads, but it doesn't have any. Any suggestions or any common areas of weakness to check?

By the way, once up and running, the car is running fine, pulling well, returning mid 30's mpg, and there are no warning lights on.

The car is coming up on 132k and has a full Volvo history to 110k, and has been maintained to the schedule independently since. The forthcoming service (due in a few miles) is a simple oil and filter job - plugs aren't due until 144k.

Cheers
DP

Thanks Screwloose. I don't suppose you'd happen to have resistance figures so I can test it??

The car started perfectly last night going home, and this morning coming in. Whatever it is, it's intermittent.

For engine code B5204T5; it should be around 2500 Ohms @20C and around 250 Ohms @90C.

Screwloose,

Thank you. This will be my first port of call if the problems continue. Again, it was fine from cold both times today.

I can confirm it is a B5204T5.

Cheers
