    How to replace a fuel pump

      befoe removing tank see if there is an access panel in the trunk. under the carpet or under the spare. if you have one you're in luck. remove panel,fuel pump will be held in by a locking ring. remove wires and lines. feed and return. pull out pump and reverse. a haynes manual from autozone will show you step by steps

      Locate the fuel pump that is mounted in the fuel tank
      Have a friend turn the key to the ON position while you listen for a high pitched hiss/whine coming from the electric fuel pump.
      If the fuel pump does not make a sound (run and prime the fuel system) check to see if there is a fuse that supplies power to the fuel pump and check its location.
      Once you have found the location of the fuel pump fuse, remove the fuse from its housing and check to see if it is blown.
      If you noticed that the fuse was blown, replace the fuse with a new fuse of the same amperage and repeat step 2.
      If the fuel pump now works, you do not need to replace it. However, you will need to find what caused the fuel pump fuse to blow. We strongly recommend that this is done through a certified shop, unless you have the tools and knowledge to test electrical systems and diagnose more in depth problems.
      If the fuse wasn't blown, it should be checked for power and ground at the fuel pump. If there is power and ground present then you will need to replace the fuel pump.
      Siphon or drain as much fuel as possible from the fuel tank. Disconnect any possible fuel lines from the fuel tank.
      Lift the rear of the vehicle using a jack and support it with jack stands.
      Remove any retaining straps or bolts holding the fuel tank to the frame.
      Using a digital multi meter, turn the key to the ON position and check for power at the fuel pump. Touch the negative lead from the DMM to a good ground and the positive lead of the DMM to the power cable at the fuel pump. You should have a reading that is equal to battery power. If you do not have a reading at all, you will need to inspect the power side of the fuel pump.
      If you have noticed that the power and ground being supplied to the fuel pump are both good, then you will need to replace the fuel pump.
      Depressurize the fuel system by removing the fuel pump fuse from the fuse box located on the passenger side of the center console. Start the engine and let it run until it stalls. Crank the engine over two more times to ensure there is no more fuel pressure left in the system.
      Remove the negative battery cable.
      Remove any retaining rings or bolts that hold the fuel pump in the fuel tank.
      Remove any electrical connections or fuel lines connected to the fuel pump. Replace the fuel pump.
      Use reverse procedure to install fuel pump and assemble all components back to their original state. Place a new O-ring between the fuel pump and the tank. Reinstall the fuel tank.
      Reinstall the fuel pump fuse and start the vehicle to verify repairs.............good luck and happy new year

    Why is the coolant light staying on?
    When I start my car the coolant light comes on and stays on. there is coolant in my car but it is very dirty and gross. Is there a way to change it? The level is at normal for cold weather.

      Put a catch container under radiator and undo plug at bottom and drain. Although it sounds like you may need a complete flush which is relatively inexpensive.

      if your car has a manual transmission, you shift the gears when you want to. there is no relearn. if your car has auto trans, disconnect battery for a few minutes, reconnect battery & drive car normally. the shift points are pre-programmed in computer. other than that, you may need your computer reflashed

      1st I would do a test on the catlic converter and see if its not pluged and 2nd I would check the TPS throttle position sensor and if these both things are fine then I would go to the transmission.

      Shifter has a bushing and a pin which probably came loose, you need to open the cover and see what you need.

      No choice, bring it to a mechanic. Tranny problems are not the DIY type. Although you can post what problems you are having with it, maybe be we can help.

      Is your check engine light on? Well even if your check engine light is off don’t assume that you don’t have any stored trouble code. You can visit AutoZone or nearby auto parts store for free diagnostic. If you have any stored trouble code, this code will help you identify the fault of your vehicle’s problem. You can also use the Find a Shop feature of AutoMD ( to see a list of shops near you with their address, telephone # and labor rate per hour.

    What is a front axle seal
    had oil changed and tires rotated. Service station said front axle seal was leaking. Said it could cause major problems.
    • HKS Guy
      11/3/2010 HKS Guy
      To make things simple, your axle spins at the same rate your wheels do, so it should be well lubricated. If there is a leak, there goes your lubricating properties, massive wear and tear.

    Why does my car stall when I brake?
    Had new a/c compressor replaced. Also had an oil change and all fluids checked. New battery. Stalls every time I brake.
    • vince^_^

      It is possible that your IAC valve is dirty, check and clean if needed. A loose/damaged/defective/idle air speed actuator/idle stop solenoid, and dirty MAF sensor connector can also cause it. If you’re vehicle is equipped with carburetor it is possible that the slow jet is clogged or the idle needs to be adjust. Is your check engine light on? Even if your check engine light is off don’t assume that you don’t have any stored trouble code, the only way to verify it is by using a scan tool.

    Automatic shifting erratic
    95k miles. problem only occurs when air is selected
      10/26/2010 MOONSTER_TOOLZ
      What do you mean when air is selected? Can you elaborate this? Have your transmission fluid check if the fluid is low or contaminated; adds or change the oil if necessary.

    Reverse not working. Feels like it's in neutral & i don't feel the gear catching.
    A couple of days ago, my reverse just stopped working. It feels like it's in neutral & doesn't "kick" into gear. It's an automatic transmission. My other gears feel like they are hesitating also, but work and I can really feel it when they do "kick" into gear.

      it could be a misalignment of the gear selector, sometimes this can happen but on some vehicles i t is not adjustable. Most of the time this is an internal problem with the transmission. Check the transmission fluid level witht he car running make sure it is not low. The best is to bring this to a transmission expert, most likely needs to be rebuilt.
