I had to disable the leveling pump on my son's 86 Olds 98 because it would turn on by itself everytime you would get in or out of the car or even if it was just sitting there. The 98 has adjustable air shock to level the car, but our 98's shocks were wore old and worn out. I disconnected the air pump underneath the hood on the driver's side. It looks like a small black air compressor near the headlights with a clear thin plastic tube coming out the back of it. Just disconnect the the wiring harness from the pump and it will stop working.
It has a float leveling sensor inside of the fuel tank, It is probley bad. The suffler in todays fuel coats the sensor and messes it up.
Replace the fuel leveling sensor that is on the fuel sending unit that's inside of the fuel tank.
The problem is : Today's gas is trash and the sulfur that is in it is taking a toll on the fuel leveling sensors and sending units that are inside of the fuel tank. Replace the fuel sending unit unless you can buy the fuel leveling sensor by itself.
You must have a 1998 or newer truck. There is no FUSE for the fuel level gauge. Now there is a fuel leveling sensor on the sending unit that is inside of the fuel tank and that is what controls your fuel gauge. It is common for the sensor to get coated with suffler that is in today's fuels / Gas. You will have to remove the FUEL LEVELING SENSOR That's in the fuel tank and REPLACE it with a new one from the Chevy dealer.
On my 05 Prius the problem was the axle height sensor located near the left rear wheel.
It senses the level of your car's rear. If it senses that the rear is too low due to weight, it sends a signal to actuate the leveling mechanism(ususally air suspension system)
Your float more than likely has a hole in it. Or it's faulty wiring. But sounds like hole in leveling sensor float.
I'm NOT 100% sure on this answer but do this and we will find out. If you are having a fuel gauge problem then CALL a Chevy parts house and ask them if they sell a FUEL LEVELING SENSOR by itself. If they do then buy it and install it on the fuel sending unit that is inside of the fuel tank and that will fix your gauge for awhile. Overtime the sulfur in the gas COATS the fuel leveling sensor and the gauge goes crazy. You may have to buy the WHOLE fuel pump sending unit just to fix your gauge. That will be A costly repair. Like I said, Don't know if they sell it by itself or not.
Defected fuel pump sending unit. The #1 cause is that the sulfur in todays gas coats the fuel leveling sensor and causes the fuel gauge to act up. It is a common problem that is starting to take place.
No, the image sensor is not a MEMS flow sensor as many think.
No map sensor is manifold absolute pressure sensor and tps throttle position sensor
