Thought it was the FICM...now she won't start!
So for the last week or so my 05 F250 has been acting up. Losing power, rough starts, and general poor performance. It gradually got worse until yesterday morning when I couldn't get it to run without stalling. I just bought the truck three weeks ago so my first inclination was to do the normal maintenance stuff (i.e. oil/filter change with Rotella T5) and fuel filter change. From all of the things I read it seemed like the FICM was the culprit but it tests at 48+ volts both with the ignition on and the engine cranking. Since I changed the fuel filter the engine started right up and ran for about two minutes and stalled and I haven't gotten it to start since. I checked the fuel caps and they are tight. I also loosened the cap and cranked the engine to purge air and it filled the bowl but it still wont start! It's driving me nuts! Anybody have any ideas?
