Try spraying a little starting fluid down the throttle body. If it will run on that for a few seconds, it's a fuel problem. If not it's an ignition problem (no spark). But if you have spark and fuel but it still won't run it's time to do a compression test. If all cylinders test very low or zero it's jumped timing. Hope that helps! Jim
