Run a compression test. If all cylinders test low or zero, it's jumped timing. Spray some starting fluid down the throttle body and try to start it. If it runs a few seconds on the starting fluid it's a fuel problem. If not, it's an ignition (no spark) problem or it's jumped timing. Then run your compression test once your sure that you have spark and fuel. HTH. -Jim
