Running rough!
I just picked up a new toy. 92 chevy k2500 with 8' western plow, 136k on the clock. Truck was not running when i bought it for $1400. Kid i got it from said he had installed new HO injectors 10,000 miles ago and had just installed a reman mechanical injection pump. When he did the pump it never ran since then.
Valley was filled with diesel and two injectors were leaking down on exhaust manifold.
I pulled intake and found 4 lines finger tight to pump were leaky. Tightened the lines, reinstalled intake and tightened leaky injectors. I bled lines at each injector and the truck fired up.
Runs extremely rough and smokes black something fierce.
Timing marks are dead on on the ip to cover.
Ive never done a mechanical ip on one of these trucks before and my guess is the guy i got it from had not either.
Can someone tell me where to start. I feel like its a few teeth off. Are there reference marks on gears? Do i set cyl 1 at tdc on compression and go from there?
Any pointers would be appreciated.
