I have a 1996 Jeep Cherokee Sport with a 4 Lt engine. It died one day in town and had it towed home. The fuel pump has no power to it, but the fuel pump relay and the (ASD) AutoShutdown relay are both working. There is power at the relay station and to the relays that is next to the battery that these two relays plug into. I have changed the crank positioning sensor and the ECM, which I read might be the problem. Still it will no start. I don't hear a whine when I turn the key and there is no pressure to the fuel rail. This is a 1996 which has the fuel regulator attached to the fuel pump in the tank. If someone can tell me which wires to jumper, I can test the pump to see if it works. There are 4 wires coming from the fuel pump setup. Thank you for the help.
