CHEVY NOT STARTING WHEN WARM.

When my car is warm it doesn't want to start. It doesn't matter if it has been running or if its just a hot day(Ak 65 degrees). It just turns over and over after 8-10 trys it acts like its going to start but dies then will finally start. I've replaced the fuel pump last year and the problem didn't exist before or immediately after. Recently I've replaced the starter, selonoid, plugs, wires, dist. Cap, rotor and fuel filter. I have also had the injectors cleaned.

First check fuel pressure with a mechanical gauge, then check for spark, then injector function with a noid light. Check the FP regulator for gas in the vacumm line which would indicate a ruptured diaphram.
The fuel pump strainer could have come loose, or the pulsator is leaking.
If you have run the car out of gas, that can cause FP failure, since gasoline cools the pump.
