Well, The problem continues, we replaced all the injectors. Had a tech come out, said it wasnt throwing any codes. continued to cycle on and off untill it would run normally and finished the season. We now have it in the shop and ran the diagnostic test manually without laptop and came up with a Code 71 - Pump Control Valve Closure to Long. After wiggling wires and checking connections I guess the inevitable has happened. We will be replacing the injection Pump. I was able to obtain the Flywheel pin, Pump pin and gear puller. I did have a couple questions I was hoping to gain some knowledge on.
1. Finding TDC #1 - I was planning on taking valve cover off, following injection line #1 to cylinder and cranking slowly till the rocker is tight, indicating compression stroke and I can insert dowel pin into flywheel. Is this how everyone does it or is there a better way?
2. After the pump is installed and bled to pump, what is the best way to get it from pump to injectors. I would like to crank it with ignition off but am unsure how to do this besides the ol screw driver in starter trick. Was looking for a better way.
Thanks for the insight!
