This car vaporlocks when temp outside is 85 degrees or hotter this car after warm up driving 5 miles. It will not want to start if you bleed the fuel rail off it will start. You get air out of it I have replaced the fuel pump, cleaned the fuel injectors by removing and cleaning. New gaskets on the upper intake. Replaced the fuel tank, done all I could think of this car doesn't have a return on the fuel rail if it does I couldn't find it and I had the rail out cleaned it also. Any thing that you could tell me to check would be appreciated.

Hi rgaddis5@gmail, com, Welcome to 2carpros and TY for the donation

Problem here could be caused by one of the following a leaky injector/s, fuel pressure regulator and fuel pump check valve this will cause the fuel pressure to drop that will contribute to hard starting and vapor locking in extreme hot weather.
