First...this is where the pump is (gas tank) on the engines listed:


Illustrating fuel pump and sending unit sensor (3) on 1999-2005 4.8L, 5.3L, 6.0L Engines

Removal & Installation

  1. Before servicing the vehicle, refer to the Precautions section.
  2. Remove or disconnect the following:
    • Negative battery cable
  3. Relieve the fuel system pressure.
  4. Drain the fuel tank.
  5. Remove or disconnect the following:
    • Fuel tank
WARNING Do not handle the fuel sender assembly by the fuel pipes. The amount of leverage generated by handling the fuel pipes could damage the joints.

  • Fuel sender assembly retaining ring using a fuel tank sending unit wrench. Remove the fuel sender assembly and the seal. Discard the seal.
  • Note the position of the fuel strainer on the fuel sender. Support the fuel sender assembly with one hand and grasp the strainer with the other hand. Pull the strainer off the fuel sender. Discard the strainer after inspection. Inspect the strainer. Replace a contaminated strainer and clean the fuel tank.
    • Fuel pump electrical connector
    • Electrical connector retaining clip from the fuel level sensor
    • Sensor electrical connector from under the fuel sender cover
    • Fuel level sensor retaining clip
  • Squeeze the locking tangs and remove the fuel level sensor.
  • Remove the fuel pressure sensor.
  • To install:
    1. Install or connect the following:
      • Fuel pressure sensor
      • Fuel level sensor
      • Sensor retaining clip
      • Electrical connector to the fuel level sensor
      • Electrical connector retaining clip to the fuel level sensor
      • Fuel pump electrical connector
      NOTE Always install a new fuel strainer when replacing the fuel tank fuel pump module.

      • New fuel strainer in the same position as noted during disassembly. Push the strainer on the bottom of the fuel sender until the strainer is fully seated.
      • New seal on the fuel tank
      NOTE The fuel pump strainer must be in a horizontal position when the fuel sender is installed in the tank. When installing the fuel sender assembly, assure that the fuel pump strainer does not block full travel of the float arm.

      • Fuel sender assembly into the fuel tank
      • Fuel sender assembly retaining ring
      • Fuel tank. Install the fuel tank strap attaching bolts. Tighten the bolts to 30 ft. lbs. (40 Nm).
    2. Refill the fuel tank. Install the fuel filler cap. Connect the negative battery cable.
    3. Turn the ignition ON for 2 seconds.
    4. Turn the ignition OFF for 10 seconds.
    5. Turn the ignition ON.
    6. Inspect for fuel leaks

    SOURCE: ABS problem with GMC 2002 Sierra

    its a low speed abs activation the problem is in the front sensors they need to be cleaned or replaced they [or one] probably has some corrosion on the sensor --[the 99 chevy tahoes had a limited recall over this issue and the fix was to remove and clean the abs sensor or if to corroded replace ] this problem doesnt set off an abs code or trouble light also sometimes the abs will activate by itself at under 4 mph without even touching brake

    Power steering assembly diagram on 2002 Sierra 5.3L if the seal can be changed out

    The seal can be changed. You will need to remove pitman arm and remove clip that holds in pitman arm seals. Once clip is removed put a bucket under it and start truck, turn and hold wheel all the way one way and seal will pop out. When installing new one first put some Vaseline on it so you don't tear it on the install. This is also a good time to change your fluid

    Bleed power steering/brake unit 2002 GMC Sierra 3500

    The slash that you placed between the words steering/brake have me concerned. I certainly hope you did not think that these two systems are co-joined? The power steering system is a hydraulic system completely separate and isolated from the brake system. They also use two completely different types of fluid. Putting brake fluid in the power steering system would destroy it just as putting power steering fluid in the brake master cylinder will destroy it. The type(s) of rubber used in the seals for each of these systems demands they use their own fluid. Any cross-contamination will require a complete draining, cleaning, and replacement of ALL rubber components and seals. This would include the power steering pump and rack for the power steering system, and for the brake system the master cylinder, all calipers and wheel cylinder as well as the proportioning valve. If there is an ABS unit, it will need serviced as well.

    My power steering in my 2001 GMC sierra does not work. Someone said maybe it was the pump, but then it was said maybe its the rack and pinion. There is absolutely no power steering, but there isnt a noise...

    Well it really could be either one.
    The impeller or a valve inside the pump could have failed, and so could a seal inside the rack.
    You would need to disconnect the pump and test it to see if it is capable of pushing fluid.

    Power steering and brakes stopped working in my 2003 GMC sierra 2500 HD..replaced water pump and belt..still not working..

    You probably have hydroboost brakes and that system is powered by the power steering unit. If you have no steering and brakes, the first thing to check is the power steering pump. Check for low/no fluid. If the fluid is okay then the pump might not be pumping and you will need to replace it.

    1993 Gmc Seirra Power Steering

    You will have to remove the serpintine belt off take off the Hoses from the steering box be carefull not to strip them out, use some WD-40 or something the make it easier if they wont come off take your time and work them back and forth, If your just doing the pump then take the hoses off the pump not the steering box, take the retaining bold out of the steering pump and it should come right off.

    2002 GMC 2500HD Duramax No power brakes or power steering

    TEST the vacuum pump. Both systems are run by it. Pressure should be at least 10psi right out of pump at 1000 rpm.
    P.S. If pressure varies more than about 4 psi as the rpm vary the pump is failling.
