Right people got a problem have had it for last 5 months or so, but now the weather is better ive started driving the escos more

right what it is, when the cars completely cold it will start straight away

but say if i drive it for a bit (car warms up etc), turn it off go away for 10-15 mins or whateva come back and it will turn and turn but will not fire

if i leave it for some time, sometimes upto 40 mins then it starts

anyone got any ideas what this could be, as it can become annoying walking back to your car and hoping it starts

 

Wrong section m8, what ST is it? And have you got a induction kit on it?

 

ST= Small Turbo

 

Heat soak into the coils could be to blame if they are on their way out, sat on the cylinder head isn't the best place for them

 

I've got exactly the opposite problem with mine

 

Hello m8
I had same kind of problem on my st. Turned out to be a faulty cps. The sensor is still available from ford, did not cost many euros. Easy to change, just loosen one pinchbolt and slide the sensor out of its bracket. The bracket is situated at the front end of the crankshaft/oilsump. The heat coming from the sump/engine via the bracket cause the sensor to fail. Can easily be verified by cooling the sensor with compressed air when the fault occurs. If it stars after short period of cooling, thats the problem. Hope you find the problem, and whats causing it.
