SOURCE: Where is fuel pump located in 1999 Oldsmobile Bravada?

The electric pump is attached to the fuel sending unit, located in the fuel tank.


  1. Properly relieve the fuel system pressure.
  2. Connect the negative battery cable.
  3. Drain the fuel tank, then remove it from the vehicle. Refer to the procedure found later in this section for details.

    Using the GM fuel gauge sending unit retaining cam tool No. J-24187, J-36608 (or equivalent) or a brass drift and a hammer, remove the cam locking ring (fuel sending unit) by twisting counterclockwise. With the locking ring released, carefully lift the sending unit from the fuel tank.

    Remove the fuel pump from the fuel sending unit, by performing the following procedures:
    1. Pull the fuel pump up into the mounting tube, while pulling outward (away) from the bottom support.

    When removing the fuel pump from the sending unit, be careful not to damage the rubber insulator and the strainer.
      1. When the pump assembly is clear of the bottom support, pull it out of the rubber connector.

    To install:
    1. Inspect the fuel pump hose and bottom sound insulator for signs of deterioration, then replace, as necessary.
    2. Push the fuel pump onto the sending tube.
    3. Using a new sending unit-to-fuel tank O-ring, carefully lower the sending unit/fuel pump assembly into the fuel tank.

    When installing the sending unit, be careful not to fold or twist the fuel strainer or it may restrict the fuel flow.
    1. Secure the sending unit by turning or driving the lockring clockwise and into position under the tabs.
    2. Install the fuel tank assembly to the vehicle.
    3. Connect the negative battery cable and check for proper pump operation.
NOTE: A special tool is usually available to remove or install the fuel pump locking cam

A brass drift and a hammer can be used to loosen the fuel pump locking cam

Once the locking cam is released it can be removed to free the fuel pump

Where is the fuel filter located on a 1992 oldsmobile custon criuser

The fuel filter in the Oldsmobile Intrigue is located under the car in front of the fuel tank. The purpose of the fuel filter is to pull out any debris and sediment that may have been sucked up by the fuel pump in the tank. Harmful sediment and debris can be hazardous to the engine. Replacement of the filter should be done every 30,000 miles.

91 oldsmobile custom cruiser will not start, did test and we get spark. The fuel pump continuously run when key is turned. Have replaced fuel pump relay. Next suggestion was to replace ecm fuse - but...

The bigger question here is whether or not the fuel pump is delivering fuel when it runs. Fuel pumps work on pressure. Once the pressure builds up in the fuel lines it will shut off until the pressure drops, then it turns on again. The fact that your pump doesn't turn off suggests that either it's not pumping any fuel out of the tank or it's not building any pressure. First thing to do is make sure there is fuel in the tank. It's possible your fuel guage has stopped working and is giving a false reading.Start looking for gas leaking under the car. A leak that let's the pump run continuously should leave a very visible wet spot. Look at the top of the tank as best you can too. Loosen the fuel line at the throttle body and see if you have pressure there. Maybe it's pouring fuel into the engine and creating a flooding condition. The fact that it runs continuously would suggest the problem isn't the filter. If the filter was plugged it would build pressure. If you can't find anything here I think you are going to have to drop the tank and start looking in there to see why it isn't picking up fuel, possibly replacing the pump. Hope this helps.

Engine stall

Possibly fuel filter blockage or fuel pump efficiency.
I suggest....don't drive until resolved. Risky business to have a stall at any speed.

Hello I am pulling my hair out because i cant find the problem to my car. I have an 89 Oldsmobile Cruiser and The car will Not start it will turn over but just not start as if were not getting any fuel. i...

You have laid out an excellent explanation of what you have checked. From this I would check into whether or not the fuel injectors are being actuated. Since you have spark and can fire it with ether then I'm wondering if injectors are being pulsed by engine control module or computer? (my experience is with foreign cars with Bosch electronic fuel injection, not familiar with Olds, but cars are cars right?)
Hope this helps, good luck!
