When you have the no start, check for grounding at the injectors. A cheap test light can be used. Find the injector plug and probe with switch on. The one that stays lit is the power. Go to other wire and have someone crank it over. This is the ground side, which the pcm controls.you should se the light flash.if not your pcm is not firing the injectors. Doesn't mean bad pcm tho. Check ASD relay. Swap another relay and see if problem goes away. Check voltage to sensors, TPS, IAC, ect. Should see 5v on a wire of each sensor. This will verify comp is providing reference voltage. Coil can do it also, but I believe the problem is elsewhere. Check the basics...when it no starts. Do you have spark? Do you have injector pulse? Find out what's missing and it'll lead you to the problem
