One of the hoses to the tank must be the source of the leak....drop the tank down again and look to see if you can tell wich hose it is coming from. You may have to dry off the fuel so you can see where fresh fuel is leaking from, try not to inhalt too much of it and do this outside. Also beware of any sources of ignition- no bonfires today, ok? Good luck

My check engine light is on. it is pulling 4 codes P0302 P1670 P0174 P0171


code p 0302 is a misfire on no 2 cylinder
check that the plug lead is on properly, that the lead is operational
move the injector from 2 to another cylinder and see if the misfire follows the move
code p 0174 refers to system too lean bank 2===causes intake /exhaust leak---fuel pressure / pump---injector/s--AIR system--hose connection/s
code p 0171 refers to system too lean bank 1=== causes intake /exhaust leak---AIR system---MAF/VAF sensors---fuel pressure / pump---injector/s -- HO2S
You stated that you replaced the O2 sensor but that is different to the HO2S sensor , does a different job and controls the air/fuel mixture from the ECM
because it has banks 1 and 2 it is a v engine and you will have a HO2S in the exhaust manifold or before the cat converter for each exhaust
O2 sensors are after the cat converter and confirm the HO2S settings for the ECM
to put the lights out , use a scan tool to reset the ECM

Replace fuel pump


Best to do this in a well vented area because of the fire hazard, so that the gas fumes don't accumulate.
1) Disconnect battery negative cable.2) Jack up car and support on safety Jack stands3) Siphon gas out of tank4) Remove three rubber hoses on rear of tank. These are used for gas fill up; remove hose clamps and disconnect.5) Remove three hoses from front of tank; these hoses go from the fuel pump to the engine. You'll need special fuel line wrenches for this.6) Disconnect two connectors at the front of the tank.7) Remove two bolts that hold the exhaust pipe heat shield. You'll want to use penetrating oil on these; they will be corroded.8) Support tank with a floor jack. Remove the bolts which hold the tank in place. Pivot the tank on the exhaust, tilt and slide out.9) The gas hoses are taped to the tank. Remove the hoses. The fuel pump plate has about 12 screws around it. Remove the screws. Lift the plate out. The fuel pump is retained with one screw. Remove the screw. Filter is retained with a clip; remove it.10) Get your new fuel pump ($250), the rubber gasket for the fuel pump plate, and new filter ($5). Compare the pump with the old one; it must be the exact lenght. I had to go to two different auto parts stores before I got the right one.Installation is opposite of above. Good luck!Fuel pump is not too tough. First, get a Haynes or Chilton manual for reference (about $14).Best to do this outdoors, so that the gas fumes don't accumate.

Leak on bottom fuel tank


There are some products which will repair a fuel tank. It depends on the leak.

Some of the products require removing the tank, adding the leak chemical and swirling the mixture inside the tank. Other products are like JB Weld which could work, but there are specific chemicals just for this job.

If you have rust on a 1999 vehicle, it can cost you less to replace the tank new, than to buy chemicals and lose gas when they do not work. Rust is especially hard to guarantee a repair on. Fix one place and another leaks a day later.

Check out the Internet for new tanks. It will be harder to find an old tank because most are ripped off before the Salvage cars are allowed on the lots.

Radiator shops sometimes do this repair.

I hope my solution is helpful.

My mother ahs a 2000 Satyrn S Series (SL-1) 1.9 L SOHC and she says that when she drives her car it sounds like an airplane. She says that it's really loud and it sputters. I have the Car MD and it gives...


If sounds really loud and the sensor is showing that code, check the exhaust. They will put it up on a lift for free to see the problem of a "loud noisy sounds" maybe even find out what is wrong with it. Just a shot for a little free help. Might be exhaust since it is so loud. Could be exhaust manifold or something stuck under the car.

How do we replace the fuel pump in a 2001 Chevrolet Malibu?


Welcome to Fixya

Here's the procedure on how to install/replace fuel pump for your Chevy malibu.


•1
Raise the rear of the vehicle and place jack stands under the pinch welds on the lower body rocker panel. There are reinforced areas here that are designed to support the weight of the vehicle. Lower the car onto the jack stands and remove the floor jack. Unscrew the fuel filler cap to help relieve pressure that builds up in the tank due to fuel evaporation.
•2
Disconnect the plastic fuel lines leading from the tank to the front of the vehicle by pushing in on the line while depressing the quick disconnect fittings. Unplug the vapor return line and the fuel pump's electrical connector. Remove the fuel filler neck hose by loosening the hose clamps with a screwdriver and prying the hose loose with a large pry bar.
•3
Remove the two rubber exhaust system hangers located near the rear of the exhaust. This will allow the exhaust to move when removing the fuel tank. Remove the metal heat shield from the bottom of the car.
•4
Place the floor jack under the fuel tank, with a large flat piece of wood between the jack and the tank, and lift the tank slightly. This will take the weight of the tank off the straps attaching the tank to the undercarriage of the car. Remove the straps holding the tank to the body of the car, and lower the fuel tank. Slide the fuel tank past the exhaust system, and out from underneath the car.
•5
Remove the fuel pump assembly by turning the spring-loaded retaining ring with the hammer and chisel. Lift the whole assembly out of the fuel tank by lifting the assembly up and then rotating it over to clear the level sensor arm. Unsnap the top, and separate the plastic housing to gain access to the fuel pump. Remove the fuel pump electrical connector, and remove the pump from the assembly by pushing the pump up and over until it clears the assembly.
•6
Install the new pump into the assembly using the new rubber coupler and the new vibration cushion supplied with the pump. Plug the electrical connector into the new pump, and snap the two halves of the plastic housing back together. Install the assembly back into the tank, and rotate the spring-loaded retainer using the hammer and chisel.
•7
Reposition the tank under the car, and lift the tank into place with the floor jack. Install and tighten the retaining straps, heat shield and filler neck hose clamps. Reinstall the exhaust system hangers. Plug the electrical connector back into the assembly. Reconnect the fuel lines and vapor line.
•8
Lower the vehicle off the jack stands and prime the fuel system by cycling the ignition key from off to run a few times. Start the engine and check for leaks

Thank you for using Fixya!

Gas tank keeps blowing a hole in exact same spot over exhaust


Hoping the exhaust system is original equipment and undamaged, After replacing the tank a3rd time, I would ABSOLUTELY assess the condition of all exhaust hangers, and re-align exhaust pipes AWAY from that gas tank. The vehicle will best be repaired on a lift, along with some heavy bars. Maybe the closeness of the exhaust was trying to bring your unleaded to a boil. Repair this ASAP

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.
