Should try and get the engine codes read, that always points you in the right direction for repair. There are so meany things to check. Fuel pressure is a big one, it should be 56 to 63 lbs. other possible causes, - Faulty spark plug (s) - Faulty ignition coil (s) - Clogged or faulty fuel injector (s) - Intake air leak - Fuel injectors harness is open or shorted - Fuel Injectors circuit poor electrical connection - Ignition coils harness is open or shorted - Ignition coils circuit poor electrical connection - Insufficient cylinders compression - Incorrect fuel pressure. You may need it towed to a trusted garage for repair.
