Ensure Engine Control Module (ECM) terminal voltages are okay.
Check for poor connections at ignition coils, Throttle Position (TP) sensor, Mass Air Flow (MAF) sensor, Crankshaft Position (CKP) sensor, fuel injector, fuel pump relay and ECM.
Check that MAF sensor and CKP sensor output signals are normal.
