Hmmwv Fuel Issue after IP replacement

[RayGunSlayer]

Well guys I have some good news! The injection pump timing was definitely off, talking about with the mark on top of the pump. I adjusted it to try to match what my old pump looked like as far as how it was lined up with the timing mark. It worked perfectly after that! I haven’t turned the fuel back down just yet but I plan on doing that here soon just because I don’t want to have to worry about my EGT’s. Thank you all for your suggestions. I appreciate the help

Late question, but.... on the original pump were the lines on the IP and harmonic balancer lined up even?
With the new IP pump mounted would you say that the IP mark was towards the drivers side or passengers side of the mark on the harmonic balancer.
I'm curious because the mark on my IP is about 3/16" towards the passenger side of mark on the harmonic balancer, which is retarded. I was thinking of moving the IP so that both marks line up and see how it drives. thanks, Mark
