Here Comes Chaos.....
Hey guys.
My father borrowed my truck one day to haul a load of firewood. He put fuel in it beforehand.
What are the symptoms of bad fuel or gelled fuel?
Right now i've got a P0251 and P0370, which Bill Heath says when those together pop up it indicates a bad LP. The LP was warrantied out not 2-3 weeks before all this started and it has great flow and pressure. The warrantied one had great fuel flow and pressure afterwards i found out, and my fuel psi gauge was bad and maxing out at only 4 psi. I thought it was bad because i had gotten a P0251 and P0370 on the ride back from a large parts run two states over to Massachusetts a few months ago. Swapping the LP made the codes go away and stay away.
along with the two above codes i get extended cranking to start the truck, outside and engine temperature doesn't matter. Once the engine is running the idle will lope from 900 to 400 all on it's own, all the while puking black smoke from the exhaust. Sometimes it'll lope once or twice and clear up and run fine, other times it'll lope for what seems like eternity, but it'll always clear up and run fine afterwards. Other symptoms include Coughing, sputtering, misfiring all during the time the engine is loping, and it's even died altogether a few times on me.
Strange thing is this comes and goes. When it runs fine it runs perfect. I tested to see if it was a fuel supply issue by heading to the mile and 1/2 long 6% or so grade by my place. I started at the bottom of the hill and kept the go pedal pinned the entire time. Pushing 15 psi boost and running with full power up the hill. It ran perfect, no coughing, nothing. Then about a mile later, the symptoms showed back up again, along with the check engine light and a change in the diesel rattle. I promptly shut the engine off and restarted it, and the extended cranking and loping idle were back as well. The loping idle and coughing/etc is only when starting the truck. Once running it's fine. It passed the hold at 2K RPM test as well. All the symptoms come and go at the same time.
Could this be bad fuel? New fuel filter was installed the first day this started. No change. No WIF light. Added 1/2 a bottle of Power Service white bottle and 2-stroke oil, cleaned up battery connections and grounds and nothing seems to have helped.
Could my IP be dying? The truck has 188K on it with evidence that the IP was changed before by a dealer but i've no idea what mileage it was changed at.
I'll get a video once the freezing cold winds and snow dies down a tad.
Thanks guys,
