My brother changed the injectors on our 5000. He says it started right up and ran fine, but he saw leaks on the injector bodies. He took the lines off and tightened the injector bodies. (aftermarket parts) Then it was only running on a few cylinders. Then he asked for my help. I determined which cylinder wasn't firing--nothing but foam at the injector and then it started running on 2 cylinders, the adjacent injector was foaming too. There's no air in the filter or pump when you open the bleeder screws. A few days later, I try again--this time I use the crank at full throttle with stop pulled and lines cracked bleeding method (forgot about that before). I got back the first cylinder but the second is still foaming even after lots of cranking and running open time.
I think it's the injector pump at this point. There's still no air at the bleeders so there has to be a check valve or plunger problem.
am I on the right track?
thanks
