Engine will roll over but wil not start whats wrong?

Check the fuel pressure, the fuel pump could be damaged. This could be the problem if the car is not starting but the engine will roll over.

Well start by checkig for spark the three basics first Compression, spark, fuel. One of those three are not happening so start by checking fuel delivery most likley fuel pump or fuel relay also check ignition module
