Ricearu Posted October 11, 2009 Share Posted October 11, 2009 I put an engine in a 86 Wagon for a friend, now everything is gravy, but the fuel pump won't kick on. The book says something about a revolution sensor and I can't find what its talking about... The Fuel pump is NOT getting power. I Have checked the fuse. It is good. It will "run" on ether(starting fluid), so I know the dizzy is "good" The fuel gauge is pegged at empty, even though I dumped 4 gallons in it... Not sure if this is related though Will I need to rewire hot from fuel pump fuse, or does anyone have a solution for this? Link to comment Share on other sites More sharing options...
SoobieDoo Posted October 11, 2009 Share Posted October 11, 2009 Yes, I'd try running a hot wire to the pump. Did you disable a ECU?...it is needed to run the pump, unless you re-wire it. Link to comment Share on other sites More sharing options...
torxxx Posted October 12, 2009 Share Posted October 12, 2009 A lil bit more info would be very useful. Carb or Fuel Injection? Did you check the fuseable links up front next to the battery? your fuel gauge wiring is on a different circuit than the fuel pump its self. The wiring for the fuel lvl sender is plumbed into the top of the fuel tank underneath the carpet in the truck/back compartment area. its not uncommon for the ground wire to corrode off the sending unit (mines done it a few times) If your car is Fuel Injected, the pump only gets power for the first two seconds the key is turned on and then it turns off until the engine runs. Carb'd the pump will run the entire time you crank on the engine. Fuel injection has a fuel pump relay that sits on top of the ECU right next to a brown square ignition relay. The fuel pump relay has a darker blue connection and its a round relay. Check that, switch it out with one of the head light relays. Link to comment Share on other sites More sharing options...

SoobieDoo Posted October 15, 2009 Share Posted October 15, 2009 Did you check for an ECU? You may have had a feedback carb originally. Link to comment Share on other sites More sharing options...
Ricearu Posted October 15, 2009 Author Share Posted October 15, 2009 No ecu. It is an origional texas car. does anyone know where the revolution sensor is? When I crank it the tach does bounce, so I know its got signal to tach. The owner has a NON california, carb'd parts car that I can take it off of IF I knew where it was located...

GeneralDisorder Posted October 15, 2009 Share Posted October 15, 2009 Should be under the dash near your left knee. It's a box about 1"x2"x2.5" or so. Should have a 6 pin connector that plugs directly into the front of it. It's most likely black. Dig around under the dash around the area of the hood release - you should find it near there.
