Check for spark from the plug wires while a helper spins the engine over! Got to have spark also before it will run.
ok well to add to the mystery .. my friend covered the end of the air intake on the throttle body while I cranked it a couple times it eventually started up .. BUT if he uncovered the intake it stopped running .. maybe its a vacuum issue ? could the maf ( mass air flow sensor be bad ??? or some other sensor be bad .. any ideas ..
