ACCEPTEDCheck Mark
Test the coils and the fuel injectors, in the Actuator Test Mode using a compatible scan tool. If they will operate in that mode they are OK and it is an input problem to the Powertrain Control Module. Test the output from the Crankshaft Position Sensor and the Camshaft Position Sensor using a lab scope. Be sure to verify the signals are normal and that they are in time with each other. If the signals are out of time with each other, then check the timing belt and the camshaft roll pin for twisting, causing the cam timing to be incorrect
