Question about 1999 Oldsmobile Cutlass

2 Answers

My gas needle is dropping to empty even though I have gas. I took it to Autozone because the check engine light has been coming on and it is reading " fuel tank pressure sensor" code. Could this be the problem or could it be something else?

    Hi, it may be that some wires are cut back there. Both the level and pressure sensors are at the fuel tank, but in different locations. Inspect the wiring harness from the fuel tank to the front of the car. Repair any damaged wires. If this is not the problem, you may need to replace both sensors.

    The level sensor is integrated into the pump assembly inside the tank. The pressure sensor is mounted on the top of the tank and has green, orange and gray wires. Please let us know if you have more questions, and thanks for using FixYa.

Hmm. Yes, not the sensor usually. Could be the fuel sender. The computer sees an issue. Have you ever changed the fuel pump module? Do you ever run your gas tank very low? May be time for a new fuel pump module.

Try replacing your gas cap.
A leaking gas cap will not allow proper pressure to build in the tank

Why does my Jeep odometer needle go to zero and gas peddle not work while I am driving down the road?

I don't have a solution for you yet. If I may ask for additional information please? Does the "Check Engine" light ever come on? Either way why not take it to an auto parts store like AutoPalace / Autozone / or PepBoys etc. where they offer a free computer analysis of you automobile's on board computer & engine control unit. Perhaps there is a message there that could help you diagnost the problem. Good luck.

Thanks for choosing FixYa and welcome to the site. Since your check engine light is on, you need to take it to Autozone and have it scanned. It is on because the computer in your car has detected a problem with your van. The staff there will check it for free and tell you exactly why it is on. This is the best way to solve your issue because there are over a hundred different things that can cause this check engine light to come on. Thanks for using FixYa.

You can take out the part of the dash where the guages are and change the little sensor/fuse behind the fuel guage, they should have a replacement part at orileys or autozone

I own a 2005 GMC Envoy with 70k. Today when i gased up the truck, the fuel guage stays stuck at empty along with the yellow light and bell!!! first time this ever happens to me? What can this be?

there is a float that floats on top of the gas inside the gas tank. this is connected to the sensor which goes to the fuel gauge. this float may have come off or got saturated with fuel so the sensor arm is stuck at the bottom of the tank. you can take the car up to autozone for a OBD reading but it will most likely have to have to have a new assembly. its inside the gas tank. the gas tank has to come out and it takes a weekend to do this. if you have a handyman in the family tell him you need a new sending unit in your gas tank. it may be integrated with the fuel pump as a whole assembly. you can go to for the instructions. I will send along a link. the procedure isnt too bad usually if you take your time. run it all the way down on gas and keep a spare gas can if you run out. get it home on empty and drop the tank. good luck and be careful.

It could be a bad fuel gauge in the dash unit, but....
Usually it's "The bad".
The fuel level sending wipe arm and windings on the fuel sender wear and send erratic readings.The only cure is a replacement fuel gauge sender.
The check engine light should not be related to the erratic fuel readings.
"The good".
If you have over 200,000kms or 120,000 miles on your van you need a new fuel pump anyway,so have a complete assembly put in which will have a new fuel sender on it.

you dont have a misfire, you have deeper problem with the electrical or fuel sender. Even so someone will need to get the code that is stored from the check engine light,,, to proceed.

It would be nice to know why the service engine light came on and is still on. An auto mechanic can read the code for you, or a dealer, or some parts stores will sell a device to read the code that caused the light to come on.

Take the truck to an Autozone parts store, they might do it other parts stores too, they can read the codes in the computer and let you know what's going on. There sholud be a code stored even though the light is off. I don't know why the fuel level would cause the light to come on.
