Pick up hose might have came off, have hole in it or could be stopped up. Remove hose at fuel pump from tank. Put positive air pressure into tank and see if fuel pushes out of line while doing this. Might just need priming for the first time and or could be the above listed issues.

SOURCE: replacement of fuel pump front tank 4.9L 6-cyl 1987 F-150

NO its correct, they just say that cuz its labvor itensive, kinda like a prevenative thing...there are 2 different pumps, which runs on same wire leads, thus the first one is innoperable and the 2nd is fine....sometimes with older pumps the abuse the pump might substain while replacing the other coulkd damage it.. highly unlikely....tell them to change the first pump and save the bs....Unless you want a newer, maybe more reliable pump...and an extra to set around in your garage....
good luck friend.
hope this was helpful

Removal & Installation

  1. Disconnect the negative battery cable and relieve the fuel system pressure.
  2. Siphon or pump as much fuel as possible out through the fuel filler pipe.
Fuel injected vehicles have reservoirs inside the fuel tank to maintain fuel near the fuel pick-up during cornering or low-fuel operation. These reservoirs could block siphon hoses or tubes from reaching the bottom of the fuel tank. Repeated attempts, using different hose orientations, can overcome this obstacle.
  1. Raise and safely support the vehicle.
  2. If equipped, remove the skid plate attaching bolts, then lower the plate and remove it.
On Explorer/Mountaineer models, the front fuel tank strap is bolted to the skid plate and will be disconnected when the plate is removed.
  1. Disconnect the fuel fill and vent hoses connecting the filler pipe to the tank.
  2. On vehicles equipped with a metal retainer fastening the filler pipe to the fuel tank, remove the screw holding the retainer to the fuel tank flange.
  3. Disengage the fuel lines and the electrical connections to the fuel tank sending unit/fuel pump assembly. On some vehicles, these are inaccessible on top of the tank. In this case, they must be disconnected when the tank is partially lowered.
  4. Place a safety support (such as a floor jack) under the fuel tank and remove the bolts from the fuel tank straps. Allow the straps to swing out of the way. Be careful not to deform the fuel tank.
On Ranger vehicles, the rear fuel tank strap has two connections which must be unbolted.
  1. Lower the tank a few inches, then detach the fuel lines and electrical connection from the sending unit/fuel pump assembly, if required.
  2. Remove the tank from the vehicle.

To install:
  1. Before installation, it would be wise to perform the following:
    1. Double-check the tightness of the sending unit/fuel pump locking ring. If it is already loose, now would be a good time to remove it and check the condition of the gasket underneath.
    2. Ensure that all metal shields are reinstalled in their original positions and that the fasteners are secure.
    3. Be sure that the fuel vapor valve is completely installed on top of the fuel tank.
    4. Make all necessary fuel line or wiring connections which will be inaccessible after the fuel tank is installed.
  2. Raise the fuel tank into position in the vehicle. If necessary, attach the fuel lines and sending unit electrical connector before the tank is in its final position.
  3. Lubricate the fuel filler pipe with a water-based lubricant. Install the tank onto the filler pipe, then bring the tank into final position. Be careful not to deform the tank.
  4. Position the tank straps around the tank and start the retaining nut or bolt. Align the tank with the straps. If equipped, be sure the fuel tank shields are installed with the straps and are positioned correctly.
  5. Check the hoses and wiring on top of the tank. Make sure they are correctly routed and will not be pinched between the tank and body.
  6. Tighten the fuel tank strap retaining nuts or bolts to 20-5 ft. lbs. (3-41 Nm).
  7. If not already attached, connect the fuel hoses and lines. Make sure the fuel supply, fuel return (if present) and the vapor vent attachments are made properly. If not already attached, connect the sending unit.
  8. If removed, install the fuel tank skid plate.
  9. Lower the vehicle.
  10. Fill the tank with fuel and check all connections for leaks.

Bought replacement ignition barrel and keys. Told that I can bypass transponder with wrire to fuel pump cutting away black box and energising fuel pump without damage.


Year make and model?? I am assuming the box is the fuel pressure control module. But when you bypass it, it will make the pump run at full pressure all the time. Your fuel mileage will go down. Again, you can not bypass security. I can get a fuel pump to run. Different power points. usually the security will kill the fuel pump and injectors. The injectors are grounded to fire from the PCM. good luck on bypassing them. ASD comes in to play.

The secondary air pump has failed and will need to replaced. The pump is an emissions component meant to help with cold start emissions. Replace it, clear the code & you should be fine. I hope this information was helpful.

How do i change a 2004 Lincoln LS fuel pump?


Hi. here's how to change the fuel pump. The actual electric fuel pump is in the tank on the right side. The tank is directly below the rear seat. If you remove the seat bottom you will find a 6 inch or so cover. Under the cover there is a plastic, threaded collar that locks the fuel pump into the tank. The driver's side also has a pump, but it works only my venturi effect from the electric pump on the other side. This pump is used to equalize the fuel level from left to right. The drive shaft tunnel prevents all but the very top of the tank from communicating left to right.

Cranks won't start. getting fuel and spark. replaced fuel filter, spark plugs and wires.


replace fuel pump. For some shops it is part of the 60kmi maintenance sched. The fuel pressure has to be there for the motor to run. Replacing just the pump and not the entire sender unit is about a $80.00 job, diy. Get the pump online, you'll get the same thing for half the price of the local parts store. You'll be amazed at the crossover usages of one pump.

1992 honda accord fuel pump wont engage


Check the fuse, fuel pump relay, and wiring to the pump. If all these are good the pump has probably failed and need replacing. In rare cases it can be a problem with the ECU.
