Carry a sqirt can of gas, carb cleaner or anything that will light up the engine momentarily. When it wont start, spray in the throttle body. If it starts, it is fuel related. If not,look elsewhere. If fuel related, do you hear the fuel pump run? If so the relay and punp are good. Do you have injector pulse? Does it start if you hold the throttle to the floor? It may be flooded from a leaky injector.
