Please help

Best thing to do is scan the computer. Also we need to eliminate a couple of things, make sure that when you turn your key to the on position(only), that you hear the fuel pump come on. Also you will need to check for spark. The crank position sensor is most likely your problem, but we still need to check. One more thing, try putting it in neutral and then try to start it. That will eliminate the park neutral switch being bad.
