Went out for a drive last weekend and everything was fine, pulled into a petrol station and the car started to hunt, revved it and it stalled, restarted to see black clouds of unburnt fuel from exhaust and drove home off boost.

Tried to start from cold and it wont fire and stinks of fuel

Checked injectors for leaks and there fine

Any other ideas ?

Thanks
James

Your the second one to say that mate

Any ideas how you can tell if it is that whats faulty ?

unplug it and see if it makes any difference,if not then chances are its at fault.
other than that you'd need a multimeter and check resistance.i'm sure they don't cost much so you could always try a new one or if a mate has a spare one try that

Thanks mate, i'll give it a go tomorrow

From what you've told us so far it doesn't sound particularly likely to be the coolant temperature sensor. If that fails, you'd have seen the dash needle either drop to zero or go right off the top of the scale when you first had that problem (and pulled into the garage). Did you?

Also, a knackered coolant temp sensor wouldn't be expected to stop it starting from cold, or cause the stalling/hunting problems you experienced.

Have you pulled all four plugs to see if they're wet? And, where is the stink of fuel coming from?

Is your car a '97-8 or '99 model year btw (coilpack in the centre or on top of the left branch of the manifold)?

Needle didnt do anything

Spark plugs were wet with fuel and the stink is in the engine bay and tailpipe

Its a version 5

Not quite. There is a separate sender for the temperature guage, the smaller of the two senders and the larger one is for the ECU water temperature. Both located on the flat water duct that goes over the top of the engine.

I'll try it tomorrow as im running out of things to check

As you are on a SimTek James, the first thing I would check is that the map sensor still has it's vacuum feed from the manifold. I would normally put in a new pipe straight from the manifold to the map sensor doing away with the charcoal canister solenoid, the SimTek doesn't use it anyway.

Have you checked to see whether the coilpack is producing an output?

Thanks Martyn, i'll check that as well

Got to have it ready for the next round

Coilpack and leads are about 2 months old, so hoping there ok

James,
Unplug temp sensor but just be precautios as rad fans may not work.
Also check map sensor plug and pipe as martyn said
