Cold starts are fine. When engine is hot then turned off and then started right up again it starts fine. If the engine is hot and then sits for 2 hours it will either fire and die then start on next try. fire and sputter to life or can you can crank the starter till it catches and sputters to life. Runs great other than that issue. It always starts it is just annoying. Things I have tried.

Fuel pressure regulator
EVAP purge valve
Temperature Control Sensor
Timing Belt
Spark Plugs
Fuel Pump Main Relay.

Any Suggestions I would really appreciate. Thanks

 

test your alternator

 

You might want to try replacing the evap canister, the shut off valve & the main 02 senor(s).

 

It could also be leaking injectors.

 

The car always seems to have plenty of battery power to start. Are you thinking it may be causing some kind of interference with starting?

 

Yes, I'm thinking the car is flooding, too much gas to start, too much gas from the defect.
