My car starts up fine in the morning, ill go and run a few arrands and when I turn my car off, it wont start back up. When the key is in the on position I can hear the fuel pump running and the car turns over fine but it wont start. After leaving the car turned off for about 30 mins or longer it will sudeenly start up just fine. I was wondering whats causing the car to start when it feel like it. Maybe the ignition coil? Or maybe the silenoid on the starter is over heating due to no or poor heat shield. Anyone have any answers?

Next time it refuses to start do below don't wait

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 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
