Hello,
When I start my car cold, it *bursts* into life after a couple of cranks - as it should do, and ticks over OK and all is normal.
Now, if after warming up, I run my car hard, then leave it for a *few* hours, on trying to start it back up again, it doesnt start correctly. Well, it starts (just) but wont rev. If i touch the throttle, it tries to die. I have to wait about 15 to 20 seconds with it idling and sputtering like this before it kicks into life and will rev normally.
Its been suggested to me that there could be a problem with the oil pump pressure relief valve sticking open - so when i come to start my car, I'm not getting any lift to the followers.
Does this sound feasible?
Either that or it could be dodgy fuel pressure and/or maybe a vapour lock in the fuel rail?!?
Any ideas?
Cheers.
Jules
