We have replaced fuel pump in a 98 ego metro LSi drove home ran fine. Now it won't start any ideas why it won't start.


Pam, was the fuel filter replaced at the same time that the fuel pump was replaced? If not, replace the fuel filter. Often, the filter will get clogged with debris. When that happens, the fuel pump will be ruined. Replacing the pump without replacing the fuel filter can ruin the new pump. It is also possible that your new fuel pump is defective. Now that most replacement parts are made in China and the third world, there is virtually NO quality control. I'm a professional mechanic and defective brand new parts are a BIG problem in this industry. Was the fuel pump relay replaced when the new fuel pump was installed? Always install a new relay, as a failing [your old] fuel pump will often damage the relay. This will cause problems with the new fuel pump. I would advise that you install a fuel pressure test gauge to the engine. This will allow you verify whether or not the engine is receiving enough fuel pressure. If the pump works but the pressure is low, also check the fuel pressure regulator. The web links below should help you.

FYI, there is also a "sock" style pre-filter on the fuel pump. This also needs to be replaced any time that you replace the fuel pump.

Sorry, if this is a silly question, but is a new Fuel Filter installed automatically/come with a new Fuel Pump? Or do you have to buy a new Fuel Filter and attach to the new Fuel Pump before installin


Has the filter ever been changed? Need to know year and model of the truck. Fuel filters can be near the tank or under the hood. Filters are usually separate from the fuel pump.

Okay, you need to make sure the fuel pump is getting power and that you have the lines hooked up correctly. Also, when you replace fuel pumps you need to remove the air cleaner and use starter fluid to get the engine started.

How would I replace my fuel Filter


The fuel filter is an integral component of the fuel pressure regulator, which is mounted on top of the fuel pump module, located in the fuel tank. When the fuel filter/regulator assembly requires service, the fuel tank must be removed from the vehicle, however, the fuel pump module does not need to be removed.
  1. Disconnect the battery ground cable.
  2. You dont have to relieve your fuel systems pressure because your jeep has an automatic bleeder.
  3. Remove the fuel tank assembly.
  4. Clean the area around the fuel filter/regulator.

Fig. Fig. 6: Replace the old fuel filter/pressure regulator mounting gasket

  1. Disengage the retaining clamp from the top of the filter/regulator assembly. Discard the retaining clamp.
  2. Using 2 small prying tools, pry the filter/regulator assembly out from the top of the fuel pump module. The filter/regulator assembly will unsnap from the fuel pump module.
  3. Remove and discard the mounting gasket below the filter/regulator.
  4. Before discarding the fuel filter/pressure regulator assembly, inspect the assembly to verify that the O-rings are intact. If the smallest of the 2 O-rings cannot be found on the bottom of the filter/regulator, it may be necessary to remove it from the fuel inlet passage in the fuel pump module.

Fig. Fig. 7: Check the condition of the fuel filter/pressure regulator O-rings

  1. Clean the recessed area in the pump module where the filter/regulator assembly is to be installed.
  2. Check the replacement filter/regulator assembly to make sure that the new O-rings are already installed on the assembly.
  3. Apply a small amount of clean engine oil to the O-rings.
  4. Install a new gasket on top of the fuel pump module.
  5. Press the new fuel filter/pressure regulator assembly into the top of the fuel pump module until it snaps into position (a positive click must be heard or felt).
  6. The arrow on top of the fuel pump module should be pointed towards the front of the vehicle (12 O&rsquoclock position).
  7. Turn the filter/regulator assembly until the supply tube (fitting) is pointed to the 11 O&rsquoclock position.
  8. Install new retainer clamp (the clamp snaps over the top of the filter/regulator and locks to the flanges on the pump module).
  9. Install the fuel tank assembly.
  10. Connect the negative battery cable.

Car is not getting gas to motor even after new fuel filter is installed


If you change the fuel filter and still not getting fuel to the engine, then the other possible problems are:
- Clogged fuel lines due to 'dirty' fuel.
- Defective Fuel Pump which may not provide enough pressure to 'push' the fuel pass your new filter.

Hope it helps.

Fuel pump package cover

  1. Remove the gas cap, fuel pump cover and pressure hoses.
  2. Loosen the screws and remove the filter. Remove the connecting plug from the old filter and install it on a new filter using a new gasket.
To install:
  1. Install a new filter in the direction of flow. Always replace the copper gaskets.
  2. Replace the attaching screws.
  3. Install the pressure hoses, pump cover and gas cap. Torque the banjo fittings to 80 inch lbs. (9 Nm).
  4. Install the fuel filter in the holder by positioning it in the center of the transparent holder. Be sure the plastic sleeve between the fuel filter and fuel pump is installed. Galvanic corrosion may occur in cases of direct contact between these components.
  5. Replace the cover box and check for proper sealing.

1999 jeep cherokee do you have to remove the fuel pump to replace


The combination Fuel Filter/Fuel Pressure Regulator is located on the fuel pump module. The fuel pump module is located on top of fuel tank.

The filter/regulator may be removed without removing fuel pump module although fuel tank must be removed.

REMOVAL
  1. Remove fuel tank. Refer to Fuel Tank Removal/Installation.
  2. Clean area around filter/regulator.
  3. Disconnect fuel line at filter/regulator. Refer to Quick-Connect Fittings for procedures.
  4. Remove retainer clamp from top of filter/regulator. Clamp snaps to tabs on pump module. Discard old clamp.

    5. Press new filter/regulator into top of pump module until it snaps into position (a positive click must be heard or felt).
    6. The arrow molded into top of fuel pump module should be pointed towards front of vehicle (12 O'clock position).
    7. Rotate filter/regulator until fuel supply tube (fitting) is pointed towards front of vehicle (12 O'clock position).
    8. Install new retainer clamp (clamp snaps over top of filter/regulator and locks to flanges on pump module).
    9. Connect fuel line at filter/regulator. Refer to Quick-Connect Fittings for procedures.
    10. Install fuel tank. Refer to Fuel Tank Removal/Installation.
WARNING: THE FUEL SYSTEM IS UNDER CONSTANT FUEL PRESSURE EVEN WITH THE ENGINE OFF. THIS PRESSURE MUST BE RELEASED BEFORE SERVICING FUEL TANK .

Two different procedures may be used to drain fuel tank (lowering tank or using DRB scan tool).

The quickest draining procedure involves lowering the fuel tank.

As an alternative procedure, the electric fuel pump may be activated allowing tank to be drained at fuel rail connection. Refer to DRB scan tool for fuel pump activation procedures. Before disconnecting fuel line at fuel rail, release fuel pressure. Refer to the Fuel System Pressure Release Procedure for procedures. Attach end of special test hose tool number 6541, 6539, 6631 or 6923 at fuel rail disconnection (tool number will depend on model and/or engine application). Position opposite end of this hose tool to an approved gasoline draining station. Activate fuel pump and drain tank until empty.

If electric fuel pump is not operating, tank must be lowered for fuel draining. Refer to following procedures.

FUEL TANK REMOVAL
  1. Disconnect negative battery cable at battery.
  2. Release fuel system pressure. Refer to the Fuel System Pressure Release.
  3. Raise and support vehicle.
  4. If Equipped: Remove fuel tank skid plate.

        2. Carefully lower right side of tank while feeding both fuel hoses through access hole in body. Fuel Tank Full And Not Drained Using DRB Scan Tool: To prevent fuel loss through hoses, keep left side of tank higher than right side while lowering. Do not allow hose openings to drop lower than top of tank.
        3. Continue lowering tank until clear of vehicle. Place tank on floor with left side (hose side) higher than right side
          1. Drain tank by removing fuel fill hose at tank. Fuel fill hose is largest of 2 hoses. Insert the drain hose (from an approved gasoline draining station) into hose opening. Drain tank until empty.
          2. If fuel pump module removal is necessary, refer to Fuel Pump Module Removal/installation for procedures.
