Hi majoit

Check the ECM fuse, attach a node light to the injector plug and see if you have a pulse signal. Crank the engine and see if the node light will flash very fast, if signal is present,the ignition module sends signals to the ECM to activate the injectors, coil packs and fuel pump. If the node light does not flash the problem can be a faulty ECM. Check the connection on the module harness, ECM for a bad grounds , open or corroded wires.
