    I've got a problem I'm hoping someone could help me with. I have an 86' turbo EFI, which starts perfectly fine in the morning, however after a drive and I park it for about five to ten minutes and restart it, it doesn't start. It cranks, but no start. If I give a some gas then it starts, but other than that I'd have to use some gas. So far I've changed my fuel pump and MAF sensor, but none worked.....anyone know the fix to this?

    Check to see if it's throwing codes, but it sounds like the cold start injector or cold start injector switch are faulty.

    An '86 doesn't throw codes. The ECM doesn't have that capability.

    Maybe the Idle Air Control valve needs cleaning? It controls the amount of air that can enter the engine when the throttle butterfly is closed. When the engine is shut off, it closes. A little carbon buildup can make it stick when an engine is hot. And tapping the accelerator allows enough air into the engine to allow it to start. Just a guess.
