1998.5 Cummins Loping and skipping
 

So I have a 1998.5 cummins. Installed an edge comp. drive it up the road and back. Ran fine. Then installed a fass 150 with a sumo pump. After installed bleed filters and lines. Cranked it up and it was loping and skiping. I just assumed it was air in line. So I blead all fuel lines. When I crack and injector line I can see it squirt fuel then it will stop. And then squirt etc. I should add when I first ran pump it blew fues. I didn't have a spare so I wrapped wire around to test it.
