what is it doing, problem?
my current truck got from GL and fuel system was all gummed up from non-usage by the air force reserve unit it was in, fuel turned to brown goo. It would either; not start, or if if did would go to full throttle. I did what a diesel mechanice advised me and it worked. Get the fuel tank to only have full, add in a couple gallons of automatic transmission fluid, I used Dexron II, let the intank pump circulate that thru the system for a couple hours. That cleaned it up and runs perfect Changed all three fuel filters too. just putting that out there in case it helps.
