Where is the fuel pump located on the 1999 bravada?

Look on the fuel rail where the fuel line turn toward the tank, if it's not in the fuel line it's in the tank as part of the fuel pump module.

maybe ignition modual

The fuel pump is located inside the gas tank, in order to replace it you must remove the gas tank from the car, remove the fuel pump module retaining ring and then remove the fuel pump assembly. You will need a good hydraulic floor jack, safety jack stands and a really good set of hand tools, a helper is a must. This is a about a 4 hour job. Be very conscious of the fire hazard here, fuel vapors can ignite VERY easily.

It sounds like the electric fuel pump has failed. The electric fuel pump is located inside the fuel tank, you must remove the tank to service the fuel pump.

remove the rear seat and there should be an acces cover for the fuel pump.

I have replaced Distributor cap, rotor, wires, and spark plugs in my 2000 Oldsmobile Bravada AWD smart track. To replace one spark plug I had to collapse the steering column, but everything went O.K. Did you marked the wires?. Did you reconnect them in the firing order?
The fuel pump is located In the fuel tank. Remove the fuel tank and take the fuel pump out from the top. This is part cost $300 and need some skills to be replaced.
The fuel filter it is directly in front of the fuel tank. Another one is incorporated with the fuel pump.

Hope this help (remember comment and rated).

Aftermarket fuel pump failure? Try "thepartsladi" store on eBay for low price GM OEM parts. Could also be wiring harness to fuel pump.

If its a crank but no start, i would put money on it that it is your fuel pump, ive put two in my 1999 bravada, they have updated fuel injectors too (recomended), i changed injectors all the way to the pump fully new fuel system and it runs just fine now. go to ur local junk yard and pay about 50 bucks for a used one and see it if doesnt help... i would recommend trying a used one befor u spend 300 on a new one. good luck
