Two times now within 15 minutes of putting my trooper in 4wd and climbing a small hill -- then taking it out of 4wd -- the fuel pump stops working. The first time I replaced the fuel pump, it just did it again with a new fuel pump in it. The pump is not get electric to it. I have to think that the 4wd does something electrical. In 2wd it rides like a dream. The Fuel Pump is wired to the alternator, does that make a difference? Was going to wire the fuel pump straight to the ignition switch? HELP
In the V6 engine the pump is switched on/off by a relay controled by the PCM - (seperate to the ECU) powertrain control module which 'sees' the 58X signal from the crank position sensor to switch on ,if the engine stops the pcm in 2 seconds switches ... 1999 Isuzu Trooper

Cars Hello, 2500 chevy diesel truck seems to randomly shut off, seems starved for fuel, always cranks back up so far but sometimes quickly and sometimes it takes a while. Fuel pump is working, we recently replaced alternator. Suspecting fuel injection pump or is there another fuel pump in fuel tank that could make it do this? Replaced fuel filter, added fuel cleaner.

Hi i have a '95 lincoln mark 8, and recently i have had problems starting my car, it tries to start but wont crank over, but i only have this problem some times, the past couple of days i have'nt had any problem so i'am thinking it might be a cloged fuel filter instead of a bad fuel pump, besides doesn't the fuel pump totally stop working once its defective? what is your advice because i dont wont to replace a costly fuel pump if it is not the problem and the fuel filter could be the problem.
Two things to check, when was the late time you had a tune-up done ??? next, get a fuel pressure tester. hook up to the fuel rail. key on, engine off, pressure could be at least 35 - 45 PSI. get a hanes manual #59010. it will help you troubleshoot. f ... 1995 Lincoln Mark VIII
Hi, My daughter has a 2000 GLi Lancer, which just stopped. I have checked and it has spark to plugs, it turns over but wont start. Fuel is in the line to the injectors. Could it be fuel pump, or is there fues to the fuel pump, I can't hear the fuel pump working when you try and start. Your assistance would be appreciated. Thank You John

I have a 78 VW Rabbit FI. I have recently put a newer fuse box in the car and changed the fuel pump in it. My issue is that I was going through to make sure everything is working right and it is not. None of my blinkers are working and when I turn my hazard lights on when the key is turned to the off position it kicks the fuel pump on, but does not do this when the key is turned to the on position. I am wondering if it is possible that the fuse box could be install incorrectly?
Yes, it sounds like the fusebox is not wired right. Most of it is large harness plugs, but there are also many individual wires as well, and they must not all be correct.One slow but sure way to figure it out is to disconnect the battery ... 1995 BMW 5 Series
I have a 1987 chevy silverado the fuel pump just stopped working yesterday but I finally got it to work again.

I have an 03 saturn vue, 2wd with auto trans. When driving, usually at less than 2 miles the engine shuts down at about 500 rpm like when stopping for a red light. Have to disconnect battery to reset computer, have found that turning key on to let fuel pump start before restarting seems to work. According to Saturn handbook it is equipped with a "passlock" system which shuts off the fuel pump if "it doesn't recognize the key being used?! Yesterday the car stopped while driving, but restarted
Sounds like a throttle sensor fault do to the fact that the saturn vue doesnt idle at 500 normally its uaually between 600-800. i suggest getting it hooked to a diagnostic machine to find wat the codes are cause im sure it will be several. ... 2003 Saturn VUE
2001 Mazda Protege started making a weird rata-tat noise and became hard to steer as I was going down hill. It stopped running. Was told to replace fuel pump, but I can hear the fuel pump run when turning the ignition. There is no spark. I sprayed into the air filter and nothing happened. Could it be something other than fuel pump?

I have changed the fuel pump on my 1997 chevy blazer 3 times in three months. I have changed to relay (found in the glove box), and the fuel filter. The car wont crank unless I pour gas directly into the butterfly on the top. The last two times I changed the fuel pump, the pump gradually stopped working, making a loud Whine before it quit. This time, we got it started, and running just fine for a few days, then it got where it would not crank without pouring gas in. Now, you can't here the fue

How can i fix a clogged fuel pump on a 2001 chevy malibu. the fuel pump is working ( you can hear it hum when you turn the key) I removed my back set to make sure and the car will turn over but wont start. it would start if you used starter fluid but once you stop the car dies. I changed the fuel pump relay no change.

I have bought 4 fuel pumps(not including orginal) for my 2001 Mits. Mirage. after the fourth one, we put the third one on a battery and it worked because mechanic said they should not be buring out that fast. We put the old one back in and it worked. It has been a year and it has stopped working again. Could there be a fuse or relay that is causing this or a short somewhere in the wires to the pump.
Check the contacts in the connector to the fuel pump for dirt or corrosion. There probably is a fuel pump relay in the circuit, but if it were the problem, changing the fuel pump would not provide a (temporary) fix. Another possibility is a broken wi ... 2001 Mitsubishi Mirage
