How to change the fuel pump

Some vehicles have access doors in the floorboard, unfortunately yours isn't one of those vehicles so the fuel tank will have to be removed


REMOVAL PROCEDURE
Relieve fuel system pressure. Refer to Fuel Pressure Release .
Disconnect the negative battery cable.
Raise the vehicle on a hoist. NOTE: Extreme care must be used when lowering the fuel tank. The fuel sender is made of plastic and may be damaged when lowering the fuel tank.
Remove the fuel tank.
Remove the sender unit and pump by turning the cam lock counterclockwise using tool J36608.
Remove the fuel pump from the sending unit by performing the following steps:
6.1. Pull the fuel pump up into the attaching hose while pulling outward from the bottom support.
6.2. Do not damage the rubber insulator or the strainer.

Inspect the fuel pump attaching hose for signs of deterioration.
Inspect the rubber sound insulation at the bottom of the pump.
Inspect the strainer.

INSTALLATION PROCEDURE
Install the fuel pump assembly into the attaching hose. NOTE: Do not fold or twist the strainer when installing the sending unit. This action restricts fuel flow.
Install the sending unit and fuel pump assembly into the fuel tank.
Insert a new O-ring seal.
Install the cam lock assembly.
Turn the cam lock clockwise in order to lock it.
Install the fuel tank.
Connect the negative battery cable.
Check the system for leaks.

1997 Oldsmobile Bravada Two Wheel Drive Automatic

I have a 97 bravada that keeps dying on me. I can drive it for about 11/2- 2 hours and it will just die on me and won't start for 45 minutes or so. I have had it in the shop several times we have changed fuel pump,filter ect.... Do you have any suggestions on what I may try next?

check the resistance on the crank and cam sensors alot of times the resistance goes high on those and then the when it gets hot it won't start.

Do you have to drop the tank to replace the fuel pump?

How do I replace the gas pump?

Hi:
To replace the pump, you will need to remove the fuel tank. The pump is in the tank.

If you have any specific questions, let me know.

Cost of replacing fuel pump

Just had fuel pump replaced on 00 Bravada 3 weeks ago at 93000 miles. Cost about $700 at a Firestone- parts about 350, labor about 350. Good luck.
