I have a 89 model 5.9 dodge cummins that has been swapped into an 86 gmc. Had to swap pumps because the orginal one was pouring fuel from the head unit. Got it running with another 89 non ic ve pump. I have installed a 94 and up ic,2003 turbo and manifold with exhaust brake. The exhaust from the brake out is a 4 inch to the rear axle. When the truck is fired the exhaust is grayish in color seems to smell like unburnt diesel. Could I have the timing on the pump off or has this new to me pump been fooled with? Engine has set about 8 months before firing it in its new home. Starts right off with no hesitation takes fuel good. thanks for the help.
