SOURCE: 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. Pry filter/regulator from top of pump module with 2 screwdrivers. Unit is snapped into module
6. Discard gasket below filter/regulator.
   1. Before discarding filter/regulator assembly, inspect assembly to verify that O-rings are intact. If the smallest of the two O-rings can not be found on bottom of filter/regulator, it may be necessary to remove it from the fuel inlet passage in fuel pump module.
   INSTALLATION
   
   1. Clean recessed area in pump module where filter/regulator is to be installed.
   2. Obtain new filter/regulator (two new O-rings should already be installed)
   3. Apply a small amount of clean engine oil to O-rings. Do not install O-rings separately into fuel pump module. They will be damaged when installing filter/regulator.
   4. Install new gasket to top of fuel pump module.
   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.
5. Remove 4 fuel hose shield mounting bolts and remove fuel hose shield from body.
   1. Remove fuel tank fill hose and vent hose clamps at fuel tank filler tube. Remove both hoses at fuel filler tube.
   2. Remove exhaust tailpipe heat shield mounting bolts and remove shield. CAUTION: To protect fuel tank from exhaust heat, this shield must reinstalled after tank installation.
   3. Place a hydraulic jack to bottom of fuel tank. WARNING: PLACE A SHOP TOWEL AROUND FUEL LINES TO CATCH ANY EXCESS FUEL .
      1. Disconnect fuel supply line from fuel extension line near front of fuel tank. Refer to Fuel Tubes/Lines/Hoses and Clamps. Also refer to Quick-Connect Fittings for procedures.
      2. Disconnect EVAP canister vent line near front of tank.
      3. Disconnect fuel pump module electrical connector (pigtail harness) near front of tank. Harness connector is clipped to body.
         1. Remove two fuel tank strap nuts. Position both tank support straps away from tank.
         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.
            INSTALLATION
            
            1. If fuel pump module is being installed, refer to Fuel Pump Module Removal/installation for procedures.
            2. Install fuel fill/vent hoses to tank fittings. To prevent hose from kinking, rotate each hose until index mark on hose is aligned to index tang on fuel tank.
            3. Install hose clamps to hoses. Position clamps between index marks on each hose.
            4. Position fuel tank to hydraulic jack.
            5. Raise tank into position while guiding fuel fill and vent hoses into and through access hole in body.
            6. Continue raising tank until positioned to body.
            7. Attach two fuel tank mounting straps and mounting nuts. Tighten nuts to 10 Nm (90 in. lbs.) torque. Do not over tighten nuts.
            8. Install both fuel hoses to fuel fill tube. Tighten both retaining clamps.
            9. Position fuel hose shield to body. Install and tighten 4 mounting bolts.
            10. Connect fuel pump module pigtail harness electrical connector near front of tank.
            11. Connect fuel pump module supply line near front of tank. Refer to Quick-Connect Fittings for procedures.
            12. Connect EVAP hose near front of tank.
            13. Install exhaust tailpipe heat shield.

First of all, the fuel pump is generally located in the fuel tank, not always though. Yours probably is, in did not research it. The fuel electric fuel pump turns on only when the ignition key switch is turned to the start position and then left on. A series of one or two relays along with a pressure monitor in the fuel rail delivery system may or not cycle it on and off depending on design. Enough of that. I suggest that you remove the spark plugs to see if they are oil/heavy cabon deposits.If so, professional attention is reguired. One more thing you could try is replacing the spark plug wires. the may be old/worn out/damage. This would give the engine spark a stronger spark,if worn and also replace the spark plugs.

how are the spark plugs?

would start with those.

the fuel filter is usually located under the hood by the intake manifold and attached to the firewall of the car. the pump is located right by the fuel tank and if you cant see it then its inside the fuel tank. (you will have to lower the fuel tank down to get to the pump.)

For removal & installation...

1. Disconnect the battery ground.
2. Raise and support the vehicle on jackstands.
3. On 1989-91 models equipped with a 2.5L engine, it is necessary to remove the exhaust clamp and bracket, and the transmission brace rod before removing the starter.

1. Remove all wires from the starter and tag them for installation.

It may be easier to remove the solenoid wires after lowering the starter. Support the starter before removing the wires. DO NOT LET THE STARTER HANG BY THE WIRES.

1. On 4.0L, 5.2L and 5.9L engines, it may be necessary to remove the oil cooler line bracket and the exhaust brace.
2. Remove all but one attaching bolt, support the starter (it's heavier than it looks) and remove the last bolt.

1. Lower the starter from the engine.
2. If installing the original starter, inspect the pinion gear for damage or excessive wear.
3. Inspect the flywheel gear teeth for damage through the starter mounting hole.

To install:

1. Install the starter in the engine and hand-tighten the retaining bolts.
2. Engage any electrical connections that were removed from the starter.
3. Tighten the retaining bolts and engage any cooler lines, braces and brackets that were removed. Lower the vehicle.
4. Connect the negative battery cable and check for proper starter operation.
