Hey guys. Looking to see if anyone else had this problem before. I’ll just keep it simple and not a whole story lol Filled up my tank and drove the truck for a few days. Half tank comes and I start to punch it and my afr gauge goes to 10 and the ucon fuel cut kicks on and I get a check engine light. No codes to be read. So I top off the tank and I punch it again and it drives perfect afr is at 12 at wot. Could this be a fuel pump problem? Thanks ahead of time guys.
