so i got everything hooked up and working properlly, finally, except for the engine itself. this is driving me crazy - particularly since i have to drive 1 hour each way to go work on my rig (read: expensive). so here's the thing - i'm getting fuel to the injectors, but when i pull the fuel return line which goes back to the injectors, it doesn't have any fuel in it. i re-timed my fuel pump today, as i know it was wrong. i lined up the punch-type mark on the pump gear with the "0" on the outter cam gear. that's correct, right? if that's correct, that's the last thing i should be having a problem with. i cranked the starter for, over a number of trials, close to a minute, maybe a bit more, and still didn't have any fuel in the return line. I would have kept cranking, but over the last 3 days of attempted starts I've killed my brand new batteries, so I gotta get them charged. do you think i just need to keep cranking the engine, or is there something else causing a problem?
