In this case i would say you have a broken wire to the pump,check the wire/retrace it and see if you can see any break if in doubt replace it.adrian,,,,

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.

I have a 98 colt and it cranks but won't start. It has 126,000 miles. Could it be the fuel pump?


Sure it could be , could also be ignition system problem ! Check for spark at a spark plug wire . If there is spark spray some carburetor cleaner into the throttle plate , if it tries to start you have a fuel delivery problem ! Did you check fuel pump fuse an relay ? Check for battery voltage at the relay . do you have any lights lit on the dash , security ? No Start Diagnostic Basics EricTheCarGuy

Why does my 98 subaru legacy sputter and die?


Clean your MAF sensor and throttle body. If it's dirty it will send wrong voltage to ECU, running either too lean or too rich, most likely too rich and flooded the fuel injectors.

1998 honda civic. fuel pump when key is turned on registers 10. volts then immediately drops to zero. did a tune up the day before. cap,rotor,plugs,oil and filter. drove 15-20 miles then died. checked fuel...


You should have close to 12 volts and then it drops to 0. That is the ecu priming the fuel system. Once you start yu should have 12v constant to the same wire. If your fuel pump is functioning ok, scan ur ecu for trouble codes. If there are no codes look into your coil and your icm in the distributor. Very commo for failure. Once the car dies, remove any spark plug wire on the plug side and put a plug into the end of it. Put the electrode of the plug close to a bolt on the valve cover and get someone to start the car, see if the plug is sparking. If it is you have a problem with fuel delivery, may not have injection pulse. You may also have a main relay failure

1998 gmc jimmie 4.3, 2 wd. wont start. getting no gas at the fuel bleeder valve. has new fuel pump and new fuel filter. started and ran fine after new pump and filter install. drove 15 miles and parked all...


Check to see if fuel is getting to the filter. Maybe too much dirt in lines & plugged filter? If fuel at filter, put hose in place of filter JUST LONG enough to see if fuel is getting to fuel rail.

1995 nissan pickup truck fuel problem


Fuel injected or carb? Make sure fuel line itself is clear. Some pumps are designed to self regulate (carb systems) some continually pump and a psi regulator sends back the excess fuel back to the tank (fuel inj systems) If the line is obstructed then pump can't deliver fuel fulltime.

If you think pump is not on consistent, try running a dedicated wire through a switch directly to the pump. If it works then you are looking for an electrical fault going to pump. Good luck.

1987 gmc jimmy wont start


yea you have no fuel and sound like a bad harness and the gm's are know for there fuel pump harness's! did you change it when you changed the pump? there is a lose connection somewhere in the fuel delivery system and it's pretty simply! i would check the fuel pump relay on the left hand side of the engine compartment and maybe even put power to the pump at the relay position "b" on the fuel pump relay harness and there should be a one pin connector to put power to also connected to the same position on the relay "b" the wire should be tan and white! good luck

Change your fuel filter, it may have gone it's life time and is getting to dirty to let fuel flow properly. Your fuel pump to may be getting weak, if the fuel filter is dirty the pump works harder and heats up and could be over heating the fuel pump relay too. The fuel pump relay i believe is in the glove box behind a panel that say relay, there should be (3) in there and the middle one is the fuel pump's. switch then around after you change the fuel filter and if you get a chance, check your fuel pressure at the shredder valve. Good luck and hope this help's if there is a Auto Zone around you, you can ask to use the fuel pressure gauge to see what fuel pressure you have and they'll have the step by step instructions on how to do it and takes about 5 min to do and will have the fuel filter and step by step to replace that too. Keep me posted, be glad to help.
