Our fuel sensor is messed up. We got a surge it felt like a mile before we got off the interstate. When we got to the stop sign at the bottom of the ramp our check engine light came on. We found a spot to park and turned the truck off and was started dropping our trailer to make sure we had a spot for the night. We started the truck and it wouldn't turn on. We dumped 10 gallons in the drivers side tank. It started up and we went to fill up the truck. We hooked back up to the trailer and we got one active code that said 1 action 1. Then a few minutes later it said the code was 80. I have looked online and can't find the code. What does it mean?
