It won't start it seems like its not getting fuel it cranks over fine everything looks fine and it just won't start


Have someone listen back by the fuel tank. Turn the key to the ON position. Does the person hear a humming noise by the fuel tank. You can try more than once. Wait 1 min. in between trys. If no 5 second hum then the fuel pump is out.

My 2001 chevy malibu had been working fine up until this afternoon it turns but wont start,itmakes ahumming noise even when i turnoff key.


That humming noise may be your fuel pump burning out. Try turning the key to the on position while someone else listens near the gas tank. The humming should only hum for a few seconds so you won't have time to listen yourself unless you can hear it from inside. If the hum continues and doesnt shut off, it is likely a bad fuel pump. It is normal to hear a small hum for a couple of seconds , but when it starts getting weak, it will hum louder, longer, or not at all

Car cranks but wont start


turn key to run position, do you hear a hum that stops after a few seconds? if not check fuel pump relay then the pump. have it scanned to see if you have crank sensor signal it tells your car to fire and add fuel.

I have recently purchased a second hand isuzu trooper model 1999 with manual transmission..everything goes on smoothly until one day it suddenly stopped as if it has gone out of fuel and wont start no...


No its not full with diesel fuel this is a common shut off on the isuzu. Plus the valve are always noisy . The crank sensor on those go out easy.This may not be the problem.Go to the back have someone crank it ,or if your hearing is great as you crank it do you hear a hummin noise that will be the fuel pump if you dont then the fuel pump will most likely be your problem.If you hear a humming noise as you turn the key on the fuel pump will not be the problem.Now let check spark. do you have a tach on it (the RPM) if you do crank it if it bounces just a tinytiny bit you have spark and the fuel pump will be the problem. Most common Isuzu trooper failure the ignition module

NOT GETTING FUEL . ALREADY CHANGED FUEL FILTER


This truck uses an electric fuel pump, it is located inside the fuel tank, if it is working you can hear it hum for about 1 second when the key is turned to run (not cranking engine), if you have trouble hearing it take off the gas cap and listen for the fuel pump hum, if you don't hear it you most likely need to have it replaced.

It takes a few tries to start the car. the car cranks, I turn off and then on again, may crank again before finally firing.


Sounds like a fuel problem, turn the key on and listen for the fuel pump to run, you should hear a humming noise for a few seconds then it should stop. The pressure regulator could be weak/check valve or injectors may be leaking by and causing fuel pressure to bleed down. Any other drivability issues/problems.

2003 Dodge Durango makes a funny noise when the ignition is turned both off and on. Sounds kind of like an annoying hum. Stops after a couple of seconds.


Usually the humming or buzzing noise you hear at start and turning off is the fuel pump being activated or shut down.

MOST LIKELY THE FUEL PUMP HAS FAILED, WHEN U TURN THE KEY TO RUN POSITION DO U HEAR A HUMMING NOISE FROM THE FUEL TANK? THIS NOISE WILL STOP IN ABOUT 5 SECONDS, U CAN HEAR IT BETTER BY TAKING OFF THE GAS CAP AND LISTENING THERE, IF U HEAR NOTHING THEN THE PUMP WILL HAVE TO BE REPLACED.
