Question about 1999 Chevrolet Silverado 1500

1 Answer

I hav a 99 silverado z71 and the check engine light, low fuel light, and air bag light are on most of the time, but will turn off occasionally, but i am sure that theres nothing wrong with those parts. i filled it up with gas, and the gauge usually says its completely empty, but will show half way full or completely full sometimes. i checked the fuses, and dont know what else to do

WEll, I think that you cannot be sure there is nothing wrong with the parts.
sounds like three issues, to me.

You MUST pull the codes and address what the codes indicate.

Your car uses a crash sensor in the front, center, under radiator.... This suffers from water penitration in the connector. Replacement comes with new harness, also. Easy change.

The check engine light, many things are possible here, again, it is the codes that direct you as to what to do. Throttle position sensor, essentially like a volume control, wears out and the system cannot calculate correctly and has to fatten up or go into limp mode...

The low fuel deal sounds like a sending unit, in the tank. It is so hard to get at, it is just replaced, but it is pricey....

Fuses have nothing to do with your issues.
