1990 crew with 1993 ats turbo. New glowplugs,new return line kit, new electric napa, new mechanical pump. New fuel lines, new filter fresh fuel ultra low sulfur.Drained veggie oil out and refilled with diesel. Starts without any problems.Will cruise to the mechanics shop at 1200 rpm max. When you give it any fuel it will jump ahead and eventually stall from either lack of fuel or air in line. Everthing has been checked????? Last thing is to drop the tanks and see if there is anything plugging lines. Any suggestions would be appreciated. First postl
