So I was trying to adjust the load adjusting screw and air got in the system. My friend and I tried purging it and we even used a vacuum pump. I also noticed the glow plug light wasn't coming on either.
We loosened all the unions, cranked it, and nothing came out of the injector hard lines.
Then we took the plunger screw out, cranked it, and diesel shot out. Same story with the return line screw on top of the pump.
I searched and searched and nothing was any help. I wonder if the glow plug relay went bad, but as for the purging and not having and diesel come out of the injector hard lines, I'm stumped.
Any help will be appreciated.
