Hey guys I havent been on here for a while... I have a 1990 C4 with and automatic transmission. My car is having trouble starting after it has been warmed up. It starts fine cold and if I turn it off for a minute once its warm it will start right up. But if it sits for a few minutes it seems something gets hot and causes it not to start. To clarify it will turn over, just not start. Ive already done a bit of research and found out my fuel pressure regulator went and flooded my car including the intake plenum and throttle body. I put in a new regulator and i'm back up to 39psi and its holding pressure just fine. I don't have any leaky fuel injectors. Ive replaced the fuel filter and checked to make sure the return line was clear. I just replaced the cap, rotor, coil, ICM, and the ECM. And its still having the same issue. When the car is turning over it is getting spark but it acts like its flooded even though its not. I'm starting to think a something got damaged from the fuel that flooded into my intake. So I tried the manifold air temp sensor because it could be going faulty when warm and causing my timing to become retarded. But that wasn't it either. So now I am pretty much lost here... I don't know if there are any sensors that could be bad to cause it not to start when hot? Oh also to inform you I have a diagnostic scanner and no codes are showing up.
Any help here would be much appreciated. Thanks!
