How do you replace a fuel pump on a 1999 Tahoe?
ITS IN THE FUEL TANK. YOU HAVE TO DROP THE TANK. TAKES ABOUT 4 HOURS AT HOME ON YOUR BACK IN YOUR DRIVEWAY.
It is inside of the gas tank. You will have to remove the tank to service the fuel pump. From someone who has replaced 2 fuel pumps. The 1999 Tahoe needs a GM fuel pump. The after market fuel pumps don't work. Something about not pulling enough volume I think. After I replaced with the GM fuel pump, the car worked great.
Fuel pressure test. If you cannot hear it run for a few seconds when you turn the ignition on without starting the engine, then check the fuse and fuel pump relay. If it runs but you are not getting enough fuel, replace the fuel filter. If you still have the problem have a fuel pressure test run to see if the pump is weak.
