How meny gallons of does the gas tank on my 2000 oldsmobile bravada hold?

your fuel sending unit, in the gas tank, is ast fault. replace it and all will be good.

your fuel is in your gas tank yes you have to drop the tank to replace it sorry

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.

This sounds familiar to me. I assume you replaced the fuel filter, if not, do so. Anyway, the same thing happened to be and I made it to the garage somehow and they said it was the pump, located inside the tank. 3 days later I picked it up and paid $350.00. It happened again a month later and I had it towed home ( the service garage changed hands and would not honor warranty). I unbolted and unstrapped the gas tank with a jack under it. The gauge said 1/4 tank so I figured on 40 lbs of fuel plus the tank.....wrong.... The tank was empty and the fuel pump had never been replaced. I has just never run my tank down that low before, so I had no way of knowing the gauge/float was miscalibrated. You never know....
