You should have someone turn the key on and off a few times while you hold a finger on the ECU power relay. It should click on and off with the key, every time. Does it?

Just because the key is on and the ECU is working doesn't mean the FP should run. It only needs to run when the engine is turning. The ECU turns on the FP relay for a second or two when the key is turned on but after that it only runs the FP relay if it thinks the engine is turning. > > Mark > > jesse and monica johnson wrote: >> got it... so if the ecu is not grounding the fuel pump correctly i would not get any fuel pump if i bridge the power relay. so if all grounds are good on ecu which they are this would indicate a bad ecu then?sorry for the confusion.jess >> >> >
