Hi my question is I can crank my car it will start. But if I cut it off it will not start again until 7 or 8 hrs. Later.
Do you

Next time it refuses to start, don't wait for nothing do below immediately to determine whether it's fuel or spark problem.

Cranks but no start condition:

Fuel and Spark:
Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.

Get your timing checked, check the wires to your crank angle sensor, make sure your PTU isn't faulty and get your fuel pump pressure tested
