Gas gauge not working property

Gas gauge not working properly. Told by repair man that the fuel pump modulator (I think that's what it was called) is gone. Is this anything that might have been under a recall? I was told it will cost about $800 to fix.

    THANKS, "emissionwiz!! I have an appt for a diagnostic test of the "service engine soon" light and also the fuel pump module with another garage for a second opinion. The first guy told me that the faulty gauge is making my engine light stay on (it never goes off). But when I called to make the appt for the second opinion about the gas gauge, they quoted me about $450 for part & labor....BUT said that there might be something else wrong as they didn't see why the pump module would make my engine light stay on!!

Pontiac has a problem with the sender for the fuel guage. A quart of transmission fluid in a full tank of gas usually fixes it. The "engine" light, won't be on because of that. Quite often that is the air filter or fuel cap.

No recalls, the fuel guage sending unit is sold as part of he fuel pump module, they cost about $300.00, that is what causes the guage not to work, labor to put the part in is around 2 hours.

I had my 04 Dakota towed to get repairs done an d when I got it back the gas gauge showed empty. I filled it up but could only put in 30 litres.

When you had your vehicle towed to shop for repairs, was the fuel pump the reason for failure. If so the Dodge Trucks have Fuel Pump Module in fuel tank and this assembly consists of Pump, Fuel Level sensor, Filter, reg. etc. If you were not having a problem with the gauge, this sounds like the Fuel pump module was either installed improperly or damaged during installation, My advice would be call the shop who performed the repairs or take it back to them to resolve it. Good Luck Hope this helps.

The module is in your fuel tank hooked onto your fuel pump. Its a common GM problem.

Why is gas gauge not working correctly since fuelpump was replaced.

Is this a flex fuel vehicle. If so, call the dealership and ask the parts dept. if there is a gauge module (perhaps behind the instrument cluster). This may be the culprit and needs to be replaced.

2001 jimmy fuel sending unit

if you take the time to drop the fuel tank you might as well replace the fuel pump module. this will come with a new fuel pump and level sending unit. DO NOT USE AN AIRTEX brand. they will leave you with more problems! Get an a/c delco or delphi pump. make sure to replace the fuel filter at the same time.

I have a 98 oldsmobile bravada and my fuel gauge stopped working. it has a new fuel pump in it but i cant get in touch with the man i bought it from to get the warranty information. i just need to know...

One common problem on older fuel pumps is that the contacts for the fuel gauge get corroded over time. This can be repaired rather than replacing the fuel pump. Of course you have to remove the pump to do it. On my car there is an access panel to the pump, so this is only about a 20 minute repair and $25.00.
The gauge problem could be external to the pump and be a connector or wiring problem also.

My 96 dodge neon randomly died on my while i was going down a 55 mph road. I replaced the fuel pump on it because i was told that was what was wrong with it. I located the fuel pressure gauge under the...

What you've found is the fuel pressure test port, not a gauge. It is the point to which you would attach a gauge to determine cranking fuel pump pressure.

About all I can say at this point is that you probably don't have enough fuel pressure, since it "dripped" out. Proper pressurization would have caused a brief burst or spray until the pressure fell off.

Have you tried a fuel filter?

I have a Saturn 93, 4DR, SL1, the fuel gauge does not work properly, is it the sensor or the pump or what, please help!

Hello, The fuel level sensor is mounted on the fuel pump module assembly. To replace you have to remove the gas tank and take the fuel pump module out of the tank to replace the fuel level sensor.

yes the fuel pump is inside the tank and checkout the fuel pump relay and the fuse for the sending unit first and try these websites to get more information on your car its and and if all fails stop by your local library and get your hands on a Haynes auto repair manual for your car also try so STP gas treatment in the gas tank if the car run better replace the fuel filter and i wish you the best of luck Michigan Man.
