So we changed the fuel filter thats in the frame rail yesterday, hoping that would fix the water in fuel problem. I got in my truck to head to work, and drove a good 15min. Then I get on the gas to pass a car up and the RPMs shot up and the MPH went no where. My speed started dropping and id try to give it gas and all that would move is the RPM. I pulled into a field and came to a stop and the truck sputtered and sounded rough before turning off. I tried restarting it and all it would do is crank, but not turn over. I had the truck towed home thinking it could be the fuel pump. My dad checked the fuel pump today and its working. So what could be the problem now? I want to try all possibilities before towing it to Ford.
