98 tahoe fuel gage

Sometimes it will read full, and then when you are sitting at a traffic light, the gage will drop down to empty, would this be a ground problem or do i need to replace the pump and sending unit?

Could be just a ground problem or a sending unit problem but not a pump problem.

check and make sure that the gas tank is grounded. check also the signal wire from the sending unit that it is not loose or cut. if all the wires are ok, then it is the sending unit which is faulty.

Tank empty, gauge reads 1/4, tank full, gauge reads full, tank 1/4 full, gauge reads 1/2. Engine off, gauge reads below empty. Any ideas will be welcome.


The values differ in all types of cars. Older cars peg out at 90 ohms. Newer cars range between 0 and about 400 ohms. Dis-connect the connector at the sender. Ground the sender wire and the gage should read empty. un ground and it should read full. They use a ceramic resistor in the tank that usually go bad.

MY FUEL GAGE DONT WORK


Very first thing is to check all fuses, then go directly to checking the ground connections. I actually have to pull the bed off my pickup to get to the top of the tank to fix my ground connection, I gotta replace the bed anyway. But I know for a fact it's the ground on the tank because sometimes it reads empty, sometimes way above full. And I know it isn't full.

Fuel gage does not work. The gage will read full but after driving for about 30 miles it will read empty & the light chimes on.


sounds like a bad float / sensor or just a bad ground.
Check the connections where the fuel pump goes into the gas tank. Make sure the ground is good and solid and not rusty. If wiring is good the float is probably bad

I just bought a 98' Tahoe and the gas/fuel gauge does not work. Checked the fuses and tried a new one for the gauges fuse and the gauge worked but then went back to empty. When I removed the fuse the...


The computer does a sweep test everytime it senses power. Check it next time you turn the key to run the gages do a little self test. However the fuse and gage won't be your problem. They are very bad for the fuel level sensor in the tank getting corrupted or dirty and doesn't read properly. You can try to add port fuel injector cleaner to the tank, but problem will usually reoccur. You will need the fuel tank dropped and the level sensor replaced.

My fuel gage says that im at a quarter tank but im actually on empty is there a sensor in the gas tank or do i need a new fuel gage


95% of the time it is your fuel level sensor in the tank.You will need to drop the tank to remove the sender to access.If you go to gm they make just the sensor for the sending unit.
