Check the fuses in both boxes, if none are blown test the fuel pump relay, it is in the underhood power distribution box.

    U didn't say that the relay was replaced have u checked the powertrain control module fuse? does the relay click when you turn the key on? just because you replaced it doesn't mean that there is any power comming out of it, test the relay socket for power and grounds, let me know, also considering the fact you said nothing about the realy a THANKS FOR TRYING IS UNFAIR.

No power in my fuel pump fuel relay for fuel pump


Get yourself a wiring diagram & study it & then
start testing the fuel circuit

How would you know whether you had power or
now power, to anything, working blindly?

You listen to what your told.
I wouldn't-- you may have changed a good fuel pump

I NEVER walk to any vehicle without a wiring diagram

How would you learn the system & the circuits, without one?

If your power plant to the fuel pump has no power u can run a new 12 volt wire to the pump make sure it's hooked up as an accessory so it will shut off the pump when you turn off your car

Follow the pumps wire back and @ each conector check for power with a DMM The conections can look like new but may not make a proper conection. also tug on the wires @ the connectors they may have corroded off just inside the plug case

No power to fuel pump


What you need to do is drop the fuel tank and put a new fuel pump in it. I would drain the gas and put new gas in after you get the pump changed.
