Okay, so here's my problem:
I have an 01 F550. PSD, 4X4, Manual Trans. This truck used to be a service truck with an IMT
body. I bought it as a cab chassis truck with the box removed.
The guy I bought it from had stripped the harness out of it for the crane controls. The crane had the ability to switch from high and low idle, start and stop the motor.
My issue is that it won't start. It cranks over fine but just won't start. It will hit on eether. I know it ran good before the harness was yanked.
I would like to jump the ECM and fuel pump and get it to fire and be able to work backward and find what the issue is. What are your thoughts? Would it be worth it to just get a different harness and swap it over? Anyone have any bright ideas?
