Ive been reading the threads and this is what I understand; power going into the the Fuel Pump Control Unit is routed out of the unit, to the fuel pump, when the ignition is turned to "Start". Once the car starts the fuel pump needs a signal from the coil telling the FPCU that the car is running. I have power going into the FPCU. When I turn the ignition to "Start" I have power coming out of the FPCU. My problem is that I don't have power at my pump. Not even while cranking the engine. If I have power coming out of my FPCU while cranking, shouldn't I have it at the fuel pump? What route does the wire take? On my FPCU, the terminal that lights up while cranking has two wires coming off of it which are the same color code. From what I understand one goes directly to the pump. Where does the other go? Also, if I fill the fuel bowl and start the car, i still don't have power at the pump. When I jump the pump directly to the battery, the pump works.
