Spray some starting fluid down the throttle body. It should run a few seconds on the starting fluid. If so, it's a fuel problem. Fuel injectors not spraying, for example. If it won't run on the starting fluid and you're sure that you have spark, time to do a compression test. If all cylinders test very low or zero, it's jumped timing. HTH. -Jim
