Fuel gelled what a pain, just got mine started, I have popped the P0087 twice in two days and last night the truck would not even start. It was -16 last night. I put some 911 in the tank, pulled the new filter I put on trying to fix it poured 50/50 911/ diesel in it cranked a bit, removed the filter did it again, cranked a bit and it started up. Its warming up right now but getting ready to take it for a drive. Are you in a cold climate, if not disregard what is said about your fuel gelling.
