92 379 Pete, 12.7 60...
92 379 Pete, 12.7 60 series ddec2, stop and check engine light as been coming on and off for a while, the other day went to start it, it wouldn't start so I sprayed it with starting fluid, fired up and stayed running but the tips sensor was acting up, changed the tps, srs, and trs sensors and still no start, got computer from junk yard, put on started every time, ordered new computer from Detroit put it on and no start, put junkyard computer back on still no start. Checked ecm fuse good but replaced anyway, it was behind Guages in dash, checked ign breaker it's good, don't see any wires rubbed or broken and whole wire harness was replaced 2 years ago. I'm all out of ideas I need some help now, thanks in advance!

Also has plenty of fuel, no bleed back, I'm sure it's not a fuel issue

Pretty sure it's not fuel related
Customer reply replied 4 months ago
Filters are full, has fuel pressure and volume

it sounds fuel related, you will need to check the filter, fuel pump pressure and that return check valve.

common issue with the 60 series engine

how much fuel pressure from the pump???

did you replace the return check valve??? common issue for loosing prime
