I rescued a 1985 F250 4x4 Single Cab 6.9 idi 4 speed Manual 79K miles and named him Sebastian. I should have held off on the name a few months. He's high maintenance and demanding so I may have misgendered him. I finally got him starting and running consistently and I believe we have his little addiction problem in check (starter fluid). Current project is the dash wiring. OMG I'm about ready to pull my hair out. I've removed the inside panels and I'm sealing up the cab. He came from Paradise 6 month before the fire so I figure he owes me for saving his dirty diesel butt. He was used as a "lake truck". He is straight piped to a single stack and he is the most obnoxious vehicle in town. No smog test in CA but registration at $325 a year is robbery. I've found so much information on this site that has helped me do the work myself. I'm no mechanic but I find the 6.9 easy to work on, no computers to deal with and my experience while in the Air Force as a crew chief on the KC135 helps. Here is a run down of what I've done so far. Injector pump, Injectors, Glow Plugs, Return fuel lines, fuel pump (mechanical), Alternator (3g swap) 2 new batteries and cable. I will be re-doing his under hood electrical mess after completing the cab and several months of therapy.
