Please check the vacuum leaks on your car. All hoses should be fitted correctly.

    you need the codes at this point, whatever is going on should have a check engine light coming on giving you codes. I dont think we can figure this out without seeing what the computer is saying.

What makes 2001 Pontiac Montana stall and die while driving, speed doesn't matter?


Amazing.....At this very moment in time.....my 2000 silhouette is doing the same thing....if you were unaware.....ventures Montana's and silhouette are from the same mold. Very similar in all aspects. My diagnostics have got to the fuel pump part of suspects....but I have already checked filter, relays, fuses and ignition electronics....my latest suspect is the pressure sensor that monitors the pressure of the gas tank....there is also a pressure sensor on the injector rail I'm suspicious of. I'm going to find out how to place each sensor in "okay ....fuel pump turn on and pump fuel to the throttle body" to check them. In my case....I don't smell any gas after turning the engine over....trying to start it.....sometimes for over an hour....never any gas smell....so I suspect fuel delivery is the problem. The fuel pump has several sensors that control whether or not it needs to run....and pump gas. I can hear my fuel pump run for 2 or3 seconds when I turn the ignition to the on or start positions.testing all of those sensors is my plan of action for this 3 day weekend. Your on track with your work and suspicion of the position sensors......vacuum leaks will follow the sensor checks. Vacuum leaks could cause a couple of sensors to fail too.....I dropped my fuel tank last weekend....and found the fuel pump to be in working condition.....I removed my fuel filter and punched a hole through it for free flow.....to eliminate it from the list...after checking the vacuum angle....I will move to the electronics side.....with the ignition switch first and the transmission position indicator switch following.....I've plugged my trouble code reader in and didn't get any indication of any failed electronic devices......my problem and your problem seem to be very similar, except that I am doing all of my work on the van myself. I will try to keep you informed of my diagnostics through fix it.it would be nice to know how yours is advancing too.....there are a few directions you can progress into.....hope one solves your problem....if not.....there will be more ideas to come....until I solve my problem....good luck to. Us both and onward we go......Nick.ps couldn't spell or grammar check because I'm using my phone to compose....and the typing pad covers the entirescript being typed. Sorry for any problems.

1996 pontiac firebird will start up and then it will die . The fuel pump is working.


Well the fuel filter would be an easy choice, but it could be something electrical.
You'll need to figure out if you are missing fuel pressure or spark when it stops running to know how to proceed.

No communication between pcm and fuel pump.


I would first replace the fuel filter. If it still wont start check all your fuses. If still won't check your fuel pump.

Was driving 2003 Pontiac gran am se1 started acting like it was out of gas and stalling finally just died out and would not crank up again. Installed new spark plugs and wires new fuel filter and new fuel...


Try checking the Ignition Control Module (ICM), there common to go bad and you may not be getting enough voltage to the spark plug wires to create a spark. Auto Zone should have that part and they can give you the step by step instructions to replacing the ICM with common tools. Good luck and hope this helps.
