Hi everyone. I've a problem with my 199 1.4 Polo that has me baffled.
I've just replaced the head gasket, put everything back together and now it won't start.
It turns over ok, and you can hear it trying to fire, but it won't quite run. It's just enough to get the exhaust manifold hot so I know it has spark and fuel, but not necessarily at the right time.
After playing about a bit more I noticed that it ran just for a second when the fuel pump fuse was disconnected. I've taken the fuel rail off and all seems ok. When I put it back together again it ran for a few seconds and cut out It seems like it only runs - but rough - when the fuel pressure's low. After a few seconds it seems the pressure comes up and then it stalls.
I'm guessing it's something I've done wrong when I put it all back together, but can't see what could have happened to make it behave like it does. Any ideas?
Thanks for your help
David
