2000 Montana van dies while running

2000 Montana van dies while running - it is like someone flips a kill switch. Could it be the fuel pump or is it something else? The check engine light does not come on - so I assume it is not a coil or crank sensor.

    Is that the same as hooking it up to a scanner? Someone I know did that for me - and it came up fine. There were no trouble codes at all. I also had the van at a licenced repair facility (after the first time the van quit and then restarted - after 15 minutes) and they "hooked it up" and did not get any trouble codes. So they ran it for hours, drove it around for almost an hour and then told me it was running great and that unless it "did it for them" (stopped running), they could not diagnose the problem. (And then charged me for telling me nothing! I know their time is money - but they wouldn't even hazard a guess! )At least the backyard mechanic I know had a guess - he said the fuel pumps often go in this model. The problem is happening more frequently now. The van quits and then will start up again - sometimes immediately, sometimes after a few minutes and sometimes after 15 to 20 minutes. It tries to turn over, but doesn't catch.

    Sounds like fuel pump for sure. Had this happen last year on my 2000 Montana. It lost power and missed badly was especially "fun" having to force it to go to get it home. Had 4-ways going and all. Once it was on flat areas it did better. $400 to replace fuel pump. Shop owner let me pay half to take it home then pay the rest the next two weeks thankfully.

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..

    Yes the trouble codes are read through a scanner that is connected to the DLC (data link connector), But I also recommened you have the active system test run as well, this test runs the engine through different tests and returns the results as error codes or a pass, pass is P1000, the dealer or a well equipped repair shop can run this test for you.

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

Amazing.....At this very moment in 2000 silhouette is doing the same thing....if you were 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 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 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 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 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 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 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. Associated

2000 Pontiac Montana wont start, no power to vehicle

I suspect an ignition switch problem, you need to check to see if when you try to start it if there is power to the signal wire at the starter. If there isn't, check the same wire at the ignition switch, if there still is no power, check to make sure the grounds from the firewall are secure and they have near zero resistance between the firewall and the negative battery post. Check to make sure there is power getting to the ignition switch, if there is none, then you have a broken fusible link under the hood

How to reset fuel shut off 2000 pontiac montana

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.

I have a 2004 Montana van. It will start if I turn the key on 2 or 3 times to let the fuel pressure build up in the lines. Is there a pressure switch that needs to be changed or do you think the fuel pump...

There isn't a pressure switch to replace. You need a new fuel pump because it isnt holding fuel pressure. There is a check valve in the pump that has gone bad. When you cycle the key the pump runs for 2 seconds priming the system, this is why it starts after you do this. I hope this helped.

Van won't start

There is a port on your fuel rail,Its like a tire valve push on it a see if fuel is coming out.If it isn't you will need to replace fuel filter first, If you still don't have pressure you are going to have to replace fuel pump.If you can hear the pump it doesn't mean that it is working.It does mean you have elec to need at least 35lbs pressure to fire injectors.You will need to check for spark at spark plugs to.after these test repost and we can solve this problem

My 2000 pontiac montana will start up then immediately die, if i give it gas to try and keep it running it sounds like it backfires through the fuel system

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
