95 GMC 3/4 6.5 turbo 5spd. In the last year I have been chasing basically the same problem. Wouldn't start a year ago, replaced the lift pump. Dies or jerks while driving, replaced the PMD twice last was the new and inproved? Won't start in N.M. replaced the pressure sensor. Six months later Dies while driving again but starts right up, replaced the pressure sensor again. Bypassed the fuel relay box in the main fuse box under hood, same problem, dies while driving. Last code error was fuel shut off so I replaced it. Same problem! Replace fuel filter to no avail. Used a known good ECM ran fine, hooked mine backup and it ran fine. Drove it 60 miles or so then out of the blue the same problem again..This beast may run fine for several hundred miles and then start acting up again....THIS IS THE MOST UNRELIABLE UNPREDICTABLE VEHICLE I HAVE EVER OWNED AND I'VE HAD SOME SHIT BOXES! If anyone has a good idea other than crush it please let me know...thanks in advance..mocksnix
