How do i reset the service engine soon light on my 99 gmc sonoma?
Answer Hi Service engine soon light on OBDII vehicles HAVE to be reset by a scan tool. Fuel gauge is PROBABALLY the fuel sender unit, inside the tank. This also could be checked with a scan tool to see if the data matches. (Some GM vehicles you can check, some you cannot. I just don’t remember for your particular application.) Hope this helps. Just advise from experience.
