Why won't my fuel pump work fuel relay switch and pump is good
Do you have power from the ECM to relay and/or pump or a short before the pump? Check a repair manual for the pin at ECM that goes out to the fuel pump and look for power coming out. Are you sure it not working? may not be but it could be the injectors not getting power from ECM or its wire harness to injectors in-order to open.
Check for 12v at injectors harness connectors.
