<!-- from fixya rte -->How check fuel systemm Montana 2000 - 2000 Pontiac Montana

sorry to say its not easy, droping the fuel tank is about it ,or remove filler hose and siphon it out or with a PLASTIC siphon pump
NEVER USE AN ELECTRIC PUMP .

Is your fuel gauge not working?

As with any no start issue, someone will need to figure out if you are dealing with a no spark or no fuel problem to proceed.
Check for spark at the plugs and fuel pressure at the injectors.

Replace the fuel sending unit it is in the tank. I would check the voltage going to the guage first make sure you have 12 volts at the unit.

Sounds like a leaky fuel line somewhere and the pressure isn't strong enough to go through the fuel pressure regulator. Try to locate fuel leak by smell.

There is not a resetable fuel cut off switch on your vehicle. Ford is the only manufacturer that uses these.

If you do not think you have any fuel pressure that you will need to check for power to the fuel pump. If you hit the dog on the drivers side you may have damaged the wireing harness to the fuel pump.

In the rear ,in front of fuel tank

I smell a bad fuel pump.. Easiest way to check this is have someone turn the key but not actually start the car and you stand near the tank to listen for the humming sound a pump usually makes as it pressurizes the system. If you hear the humming sound then check the pumps PSI and see if it holds. Good luck

before u replace any parts u need to have the electronic engine control tested for trouble codes, this is the 1st thing that any shop does to know where to start the repair and diagnosis. Most likely u have a defective crankshaft position sensor, but have the test run..

Have you checked your brakes
