This vehicle is fuel injected. Sometimes it starts. Lately I turn the key, the starter turns the engine over for a few seconds but it will not start. I can leave it for about an hour or so and it will start.

Lets try doing below to pinpoint if its a fuel or ignition problem thats causing it and get back so that we can continue

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -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,distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it
