On the rear of your engine you will find a metal line with a plastic cap covering a schrader valve very much like the one you use to put air in your tires. Remove the cap and depress the core. If your fuel pump is working, it should spray some fuel out under pressure. If it just barely has pressure your fuel pump is probably shot. ( This is a common GM truck problem;; my father-in-law is getting about 45,000 miles and his fuel pump is shot ...3rd one ).

AnswerIf engine turns over but won't crank turn switch to run and listen for fuel pump. If you don't hear it, whack your fuel tank with a rubber mallet a feew times (I'm not kidding) and try to crank. If it does you need a fuel pump.

Answer:

Like the guy above said. give your fuel tank a few whacks with a rubber mallet while someone trys to start it. but this will usually only work once. so once you start it take it to your mechanic or wherever your going to fix it.

Location of fuel pump for 99 TahoeIt is mounted to the inside of the frame under the driver door. Nononononononono! It is inside the fuel tank! Inside the frame is where the fuel "FILTER" is most commonly found.

It has a electric pump inside of the fuel tank.

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.

Chevy did not use them on there trucks or SUVs. You need to check the fuel pump fuse and relay and make sure there good. You may just have a bad fuel pump.

Chevy does not have a reset button, Only for had that. You need to check the fuel pump relay and fuel pump fuse. Chevy had a problem with the wireing harness going bad back where it plugs into the top of the fuel tank.

You will have to drop the fuel tank. Remove the pump assembly. The new pump should have instructions for replacing the unit.
