You will need to install a new Instrument Panel Cluster. And GM just changed the programming of these IPC's to where you will need to take it to a GM dealership and let them program it.

My 2000 Chevy s15 Rpm and Gas Gauge is not working


I didn't see an s15 in that model year, in my database?
If the speedometer works but the tach doesn't, I think something is wrong with instrument cluster?
GM has had a problem with fuel gage sending units. The sending units are not hard wired to instrument cluster, they send signal to pcm, the pcm sends serial data to instrument cluster, telling the cluster the gage settings.
It may be possible to use different size resistors in place of the fuel level sending unit, to see if fuel gage reacts properly to different resistors, if the gage reacts properly, then I think the problem is the fuel gage sending unit.

your fuel sending unit has went bad you can either replace it which is in the fuel tank (attached to the fuel pump) or wait for the fuel pump to go out

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.

I have a 99 Ford F150 with a 5.4. It will start and run fine, no codes. After 2 minutes of running the oil pressure goes to zero. Shut off the engine and restart the oil pressure will go up to normal for...


Start by verifying the oil pressure sending unit. It is quite common for a bad sensor to act erratically, such as you have described. Acquire an oil pressure gauge and install it in an appropriate location, perhaps in place of the oil sending unit if a more convenient location is not available, and run the engine. Observe the pressure on the test gauge at various RPM and over a period of several minutes as the engine warms. If pressure on the gauge is good, then you have a problem either with the oil pressure sending unit, in the circuitry, or instrument panel gauge. However, the problem is most likely the sending unit. Note: the sending unit often requires a special socket, which may be obtained at any auto parts store. Also, if you don't own a test gauge or unwilling to purchase, many auto parts stores now rent tools, others even loan tools provided an adequate security deposit is made.

Gas guage not working


Voltage from the battery goes through the ignition switch, through a device in the instrument cluster called a voltage regulator (though it is really misnamed), through the gauge, through the wiring to the gas tank, through the sending unit in the gas tank to ground.

The sending unit is an electrical wiper that slides across a peice of resistance wire. the movement of the float moves the wiper. If the sending unit no longer makes electrical continuity, the gauge will read zero. If the sending unit wiper is shorted out, the gauge will read full.

Try grounding the wire at the tank to see if the gauge maxes out, then disconnect it to see if the gauge zeros out. If all that happens, your problem is the sending unit in the tank. If none of that happens, your problem lies closer to the front of the car. While you are under there, you should measure the resistance from the terminal on the tank to ground, just to verify that the sending unit makes some electrical contact.

If the other gauges work OK (temp, oil pressure) then the "voltage regulator" is probably working fine, and the problem is the gauge itself.

If you have no other gauges (excluding speedometer, tachometer and battery voltage meter -- they work differently), then try this:

Put a voltmeter on the part of the fuel level gauge that is supplied by the "voltage regulator." The voltage there should regularly cycle between near zero to 10 or 12, back to near zero, etc. If you get that cycling, then it is most likely the gauge.

I'm resorring my first car 87' camaro none of the gauge work ex. the speed. No gas, no temp or oil replaced sending units they work now but they not cheap. I got tried of running uot of gas I'm a bad guesser.
