Why won't the reserve tank electric fuel pump shut off? It keeps pumping fuel out of the front tank filler tube. Also, fuel gauge does not work. What's wrong?

Fuel pump removal 96 nissan quest


Replace Fuel Pump for 1997 Nissan Quest

(1) If the fuel tank has more than one third full, you need to get the gasoline out. If it has one third or less full, you can leave it in the tank. However be very careful around the working area. Make sure you have read fire precautions in a general repair book. Take the fuel pump fuse out from the fuse box near the battery. Run starter for a few seconds. This will remove the fuel pressure in the gas lines. Disconnect battery at negative terminal. Jack up the rear of the van.

(2) Remove the fuel tank protector.
19add47.jpg

(3) Disconnect fuel pipes at the front end of the fuel tank. Use short pencils and extra rubber hoses to block disconnected pipes and hoses.
59aa089.jpg There are two pipes connected to the gasoline filler at the side of the van. Disconnect only the smaller one. The larger one is flex enough for the tank to be lowered.

(4) Disconnect the electrical from this connector. Jack the rear end of the fuel tank with a car jack and a piece of 2x4. Put the wood between the jack point and the tank. Then unbolt the two bolts showing in the picture.
128654f.jpg
(5) Lower the jack after the bolts are removed. The rear end of the tank should be lowered.
667f695.jpg

de57889.jpg

(6) Disconnect fuel lines on top of the fuel pump. Reconnect each short hose back to different pipes as shown in picture to block the pipes.
585888a.jpg
(7) Loose the six mounting bolts on the fuel pump assembly. The bolts should be loosen a little at a time in multiple turns. Also detach the electrical wire holders. After all bolts are removed, carefully take the assembly out of the tank.
dceea20.jpg

(8) Remove the fuel pump from the assembly as shown in picture. Then unplug the electrical wires. Note that two connectors are in different sizes, so that you will not be able to reconnect to a wrong terminal.
1310aad.jpg
(9) Put the new pump and new filter in. Reconnect the electrical wires. If necessary use a pair of pliers to make the connectors tighter. Make sure they are not loose. Reconnect gas inlet to the pressure regulator.
08db176.jpg
(10) Use a new O ring, put back the assembly to the fuel tank. Make sure the float of the fuel level senser is free, and the assembly is at the right orientation (as shown in picture). Screw back the 6 bolts after making sure the O ring is in right place. The bolts should be tightened in turns. Do not over tighten them. Then reconnect the fuel lines and make sure every fastener is tight. Put the electrical wire into holders.
90c2053.jpg
(11) Jack up the tank and put the two mounting bolt in. (see picture in step 4). Make sure they are tightened with specific torque. Reconnect the electrical connector.

(12) Reconnect two fuel lines at the front side of the tank. Refer to the picture in step 2. Reconnect the hose to the gasoline filler. Before you have a try start, double check if all fuel lines are securely connected and tightened.

(13) Start the engine. You need to crank more than a normal start because the lines were empty. The pressure is built up in some time.

(14) If engine starts ok, turn it off. Then check under the van if there is any leakage. If everything is fine put back the tank protector. (picture in step 2).

Can you tell me how to change fuel pump on a 1990 chevy lumina


http://www.autozone.com/shopping/repairGuide.htm?pageId=0900c152801dbaf3

when you drop the tank by following these directions you will have access to the pump

1989-94 Vehicles
See Figures 1 and 2
  1. Disconnect the negative battery cable.
  2. Properly relieve the fuel system pressure, as outlined earlier in this section.
  3. Raise and safely support the vehicle.
CAUTION Observe all applicable safety precautions when working around gasoline. Do not allow fuel spray or fuel vapors to come in contact with a spark or open flame. Keep a dry chemical (Class B) fire extinguisher near the work area. Never drain or store fuel in an open container due to the possibility of fire or explosion.
  1. Use a suitable hand operated pump device to drain the fuel through the filler tube into an approved container.
Before disconnecting any fuel lines from the fuel tank, thoroughly clean around all hose connections.
  1. Disconnect the fuel filler vent hose from the fuel tank.
  2. Detach the fuel filler hose from the fuel filler inlet tube on the fuel tank. Position the hose out of the way.
  3. Disconnect the vapor hose from the front of the fuel tank.
  4. Detach the fuel return pipe and position the hose out of the way.
  5. Disconnect the two rear rubber exhaust hangers from the rear of the exhaust system and allow the exhaust system to hang down slightly.
  6. Unfasten the exhaust shield mounting bolts, then remove the exhaust shield.
  7. Support the fuel tank with a suitable jack.
  8. Remove the two bolts securing the fuel tank straps, then swing the straps out of the way.
  9. Lower the fuel tank enough to disconnect the vapor hose from the fuel sender assembly and the vapor hose from the vapor pipe at the rear of the fuel tank.
  10. Detach the electrical connector from the fuel sender assembly and remove the two retaining clips.
  11. Remove the tank from the vehicle, slowly to ensure all connections and hoses have been disconnected.
To install:
  1. Clean all parts well. Inspect the tank for dents, rust or other damage. On high-mileage vehicles, it may be good practice to remove the fuel pump module and replace the flexible strainer on the fuel pump.
  2. Position the fuel tank under the vehicle and raise the tank with a suitable jack.
  3. Connect the vapor hose to the fuel tank at the vapor pipe at the rear of the tank and connect the vapor hose to the sender assembly.
  4. Attach the electrical connector to the fuel sender assembly.
  5. Connect the fuel feed and return lines to the sender assembly.
  6. Raise the tank into position into the vehicle and swing the mounting straps under the tank.
  7. Install the front fuel tank strap mounting bolts and tighten to 35 ft. lbs. (47 Nm).
  8. Remove the jack.
  9. Connect the fuel return pipe to the fuel feed pipe.
  10. Attach the rear fuel feed pipe to the inlet side of the fuel filter.
  11. Tighten the line fittings to 16 ft. lbs. (22 Nm). Make sure to use a back-up wrench to prevent the fuel filter from turning.
  12. Connect the vapor hose to the vapor pipe at the front of the vehicle.
  13. Attach the fuel filler vent hose to the tank. Connect the fuel filler hose to the fuel filler neck of the tank.
  14. Install the exhaust heat shield and the mounting bolts.
  15. Position the exhaust system and install the rubber hangers.
  16. Carefully lower the vehicle, then refill the fuel system
  17. Connect the negative battery cable, then install the fuel filler cap, if not done already.
  18. Turn the ignition switchONfor 2 seconds, OFF for 10 seconds, thenONand check for fuel leaks.
