Hello, Just wanted to get back to you. I had someone take the IP apart. Internally, there were a few bent rods on the governor system and one of the rods fell off due to being bent. How this happened, I have no idea? Did not get the pump back on yet. Thanks again.

Thank you. I have tried that but I am willing to put the pump back on and try again. Bud

davidb56 Thank you for your reply! Fuel is flowing heavy into the fuel injection pump. It is also coming out just as strong from the return side. It just isn't coming up through the top. We have tried several different tests. I pressurized the tank in order to gain fuel flow. I also...

Greetings! STILL working on this problem. I pulled the injection pump off and cleaned it as much as I could without disassembling it. Put it back on but NO luck. Nothing coming out of the top! Any suggestions on a place to get a new pump OR send mine for a rebuild? Thank you in advance!

Some additional observations: with the plug in the return line, pressure builds and very small amount weeps out of the banjo while turning it over; with the plug out, a little fuel flows out of the return hose when the turning over ceases. Do you think that heat would help at all?

I finally got a day to work on the beast. I pulled the return line off and plugged it temporarily. Still no luck!

It is definitely getting fuel up to the IP but still no luck.

Thank you very much for the input. I have four (4) new batteries and keep them on trickle charge. I had a friend watch the solenoid for me while I tried but I will wire the valve open. I work another twelve (12) hour shift tomorrow but will try your suggestion later in the week.

Yes, it does pull back/up.
