Question about 2002 Chevrolet Malibu
I filled up my tank almost a week ago and have done a lot of driving since, but my tank still reads full. Right after I filled it up and was driving home the needle went from full down to empty and the "almost empty" light lite up. It then jumped to half tank and then started creeping up to full. It said full by the time I got home. Ever since then it hasn't been reading properly. I noticed today that when I turned it on it appeared to show the real gas tank level, but then within a matter of moments it crept back up to full.
Not sure if this is relevent, but over a month ago my gas line froze and neither the level of the gas tank or the temperature of the engine would read. We managed to fix it and get it running again, reading the gas level and seeing the temperature, but I'm wondering if something may have broken then. It only stopped reading it properly last week and I've filled up between the gas line freezing and last week more than once and hadn't had a problem. Please help!
Unfortunately this is most likely the fuel pump module, which includes the fuel level sensor also. This should be diagnosed more thoroughly with a scanner, a good scanner will be able to check instrument cluster separately to confirm the gage is working right,and check for trouble codes that may not light any warning lamps. Hope this helps. Rate me please.P.S. Dont use that fuel station any more.
