there is a sort of gas sensor located usually on the side of the fuel pump, or in a separate location in the fuel tank itself. there's a little float, similar to the inside of a toilet, the senses fuel levels and relays that information to the fuel gauge. mechanical experience needed to perform this on your own, but i recomend taking it to a shop. it should be reletively inexpensive.
The fuel gauge fuse on 1998 Chevy blazer is located in the front of the blazer. It is on the driver side next to the hook latch.
We replaced the temperature gauge in my 1991 Chevy blazer what is the normal operating temp?
The fuse box for the fuel gauge on 1998 Chevy blazer is located on the driver side. It is near the hook latch.
temp sensor - sends signals to the computer for driveability temp sender - measures temp and sends to gauge in dash
The fuel gauge sensor is located in the fuel tank. The fuel gauge sensor and fuel pump are one assembly. To my knowledge they are sold as one unit and is fairly expensive. The fuel tank must be dropped to R&R the assembly.
check ground first
change your ECT sensor. It tells your vehicle if it is too hot to operate.
210 to 220 is a safe range.
because you suck it until it hurts
The voltage gauge on the Blazer is not the most accurate (cheap) When using the signals the voltage draw on the system is enough to make the gauge move slightly.
There is a temp sensor on the water inlet for the PCM, and sending units for the gauge on the side of the heads. Normally part stores don't carry the sending units.
Bad sending unit in the fuel tank.
