Filling up from almost empty. After the fill up I paid looked down gauge was on e and the light was on. Checked the cap and everything. So I drove away the light went off n went back to full. Then it kept going back and fourth. Now just check engine light. I'll check with the dashhawk when I get home, any advice?

Thanks

Its a sensor in the fuel tank its from a build up on the senor u can try using some fuel cleaner a couple of times it may help. I have the same issue and have been doing the fuel cleaner and it hasn't helped yet.

Yep. When you fill it back up it will do it again. It will also give you a false reading for miles till empty. Mine said I had 28 miles till empty and it ran out of gas less than a mile later.
