This has happened 5 times in the last week, so something is going wrong somewhere. VW 1.8 20v non-turbo. Engine starts fine cold. Runs well, no problems at all. Come back to it after being parked for 10 mins or so, and it wont start. Smell of petrol, and after turning over for a few minutes, or left for a minute or so, then turn over again and again, it will eventually start.
Once started, it runs well, once the initial excess petrol has been burnt off.
Reading a few online forums, there are a few options that it could be (it seems to be a common fault, that doesn not show up as an error code).
The temperature sensor for the cold start injector could be faulty, The cold start injector is stuck open.
Other suggestions were a faulty starter motor (apparently they have to crank over at above 280rpm to start). Seeing as it'll start fine at the
-3 degrees we had last Sunday, I cannot see how it could be a starter problem, - surely the engine will turn over faster when the engine is warm? Correct me if I'm misinformed.
Another distinctly strange possibility was a faulty ignition switch. I'm discounting this, as the only time it happens is when the engine is hot, so most unlikely to be an intermittent switch problem.
Which leads me to the cold start sensor and injector.
Are these cheap, so I could just buy them and fit them to make sure it wasnt them?
Anything else I may have missed?
Thanks for your thoughts Alan.
