99 f250 crew cab 2 wheel drive 7.3 140k
Western diesel chip/stainless exhaust.
Aux gas tank.
Light use tow road vehicle that has similar issue described in this thread.
This occurred yesterday on my Xmas eve road trip. Currently broke down in Columbus, Indiana.
Anyhoo.. Upon warm engine start up after a pitstop, the engine performance was uncharacterically sluggish. Once upon freeway I could not get speed above 45 mph. The engine exhibited rough idling when restarted , bogged down i
response to acceleration, and then eventually slowing down to stalling and currently unable to start. Normally this truck starts up like a champ!
Now the vehicle cranks fires and sputters when attempting start.
No check engine lights currently or recently . Fuel filter checked clean and found normal wear.This sputter to stall cycle progressed over 10 miles.
Presently the vehicle cranks, fires, and sputters when attempting start.
..It fires & gags but currently will not start and run.
Found a mechanic locally on xmas eve who came out with a reader.
*Codes were 1280 & 1247. Possibly stored from past events?
2 techs have said they believe the codes may not represent the current problem at hand.
CPS replaced by recall last summer tested good yesterday as well.
Fuel in tanks were from previous fills a week or so ago. I had 400 or so miles running the fuel with no problem. No fuel add/top off on trip. In addition..switching fuel tanks did not exacerbate nor relive the condition. Oil is clean and topped always.
Made calls to my A-list diesel heads.. One suggested injector wire harness failure possibility. Will follow up Monday after we troubleshoot further.
