Update on the wierdness-
Turns out it's not so wierd after all--got back home and was able to troubleshoot by wiring directly to the injector pump fuel shutoff solenoid and it still dies. Noticed that the main factor appears to be getting above 1500 RPM and then rapidly letting the RPM decay, it evidently undershoots the low idle speed stop and dies. Starts right back up and runs fine, but if you allow the RPM to drop quickly from 1500 it dies.
The guys at the IP overhaul shop say metering valve in IP problem, probably due to water or corrosion. The pump is fairly fresh but I do have to admit I haven't been as vigilant on draining the water. Anyone have any experience with this? Can it be replaced on the truck or should you pull the pump? I would like to turn up the wick too as it seems to be a bit weak.
I'm wondering if this has something to do with this new ultra low sulfur fuel (and the fact that my wife absolutely refuses to put the Howe's treatment in when she fuels the truck)?
Interesting insight into the price of diesel fuel--Believe it or not, I was at an aviation conference a month ago where jet fuel was discussed and the guy from a pretty reputable source was talking about how much diesel fuel is EXPORTED! Kinda flies in the face of the drill here and now mantra. Seems the US exports a lot of diesel, which impacts the domestic supply and hence the price. Not that I begrudge the refiners making an extra buck, but if they're getting tax breaks and incentives to pick my pocket now that may be a scandal. The exports also impact domestic jet fuel supplies as the portion of the oil barrel that could go toward increased production of Jet A kerosene gets "poached" for more export diesel fuel and voila--artificially low supply and high prices! But I digress--
It got cold here in SW Mo, not by Manitoba standards but 4F is still pretty cold.
Hope everyone has a Merry Christmas!
