    The wires going into the fuel pump should both be hot when you turn the key on. The plug can be disconnected. Have someone turn the key on while you are checking with a test light or volt meter. If one is dead and your gas gauge works, work back wards and go to the relay. Make sure the #30 pin is getting power.

    I need a Volt meter! Having a jeep,its almost a Must have. I dont have a test light either. I did jump across 30 directly straight across & i did hear it click & then about 2 seconds later click again. Im assuming thats ON then Off hoepfully. ....I just went & bought a New Fuel pump & Screen. Dreading the installion though,but Im trying to Psych myself up to go out there & Do it! Any pointers anyone wants to share before I start? i know disconnect the battery,then disconnect the 3 wires from the pump & ground, then use a hammer to lightly bump the big metal ring COUNTER-clockwise & remove that. ....thats whare i will be learning as I go,so to speak.
