Runs fine until shut off, then won't start back up. I have to wait thirty minutes then it will start. I change oxygen sensors, fuel filter, crank sensor, and fuel relay. Please someone help.

Good afternoon,

When it will not start, can you hear the fuel pump turn on? I would check the pressure to be sure it is working.

When it does not start, does the tachometer move up a little while cranking?
