replaced bad ficm still no start

03 f350 began to die intermittantly. No injector chatter on KOEO. Ficm volts were way down. Had ficm rebuilt. Truck started great ran about 100 yards then died. No injector chatter. I have completely removed and inspected the fuel injector harness (repaired a bad short on two injector wires). After reinstalling harness I get injector chatter and good start, truck runs for about 3 minutes then dies and we are back to no injector chatter. FICM voltage is 48 and I replaced the ficm relay. Any ideas? I'm quickly getting to my wits end. Thanks

I will check it today, will low fuel pressure cause a loss of injector chatter at KOEO?

Just Ficm voltage at 48 alone, does not mean your ficm is ok.

that is what I'm leaning towards, the ficm is still bad. I ordered a new injector harness (to eliminate that as a possiblity, I did find and repair rub spots in a couple of places.) The Batteries have been load tested, alternator is good, HPOP is less than a year old. Is there anything else that would cause the chatter to stop (if it chatters it will start, no chatter no start)

Found really bad short between two injector wires, ficm was fooked, I'm assuming from the short. The main harness has had an end spliced on to it (x3) I checked all of the wire colors and their corresponding pins, they match. Is there a way to ensure that the 5 ground wires (black/pink) and switched power (dark green/light green) are attached to their correct wire? Or does it even matter as it appears they are fed by a common ground or switched common bus? I just want to make sure I don't blow another ficm

Sounds like you may need a harness.
