Tried to start the C350 today after many months of changes, donor engine, rebuilt IP to 110cc, stage 1 injectors, new fuel lines from tank to injectors, new holly pump, among several other modifications.
I have a mechanical fuel gauge just in front of the ip and it's showing 5psi.
The lines are primed to the ip.
I loosened all the lines at the injectors, stuffed towels around each one, and did four "starts" about three to five seconds each.
All new battery cables, 2/0 positive, 1/0 negative, new batteries, fully charged.
The glow plug controller cycles and does it's happy clicking.
After four cycles the towels at the injectors are still dry.
Nothing at any of them.
The engine turns easily, the oil pressure gauge reads in the middle of the range after about 2 seconds.
After the four attempts to bleed the lines I turned the ignition to on and waited for the glow plugs to cycle, then with the key on grabbed a meter and checked the two connectors at the ip.
Neither one was hot, both showed 12v when I put the negative lead on each connector and the positive lead on the battery, which tells me whatever enables the ip solenoid isn't sending the signal.
FYI, this is my first ever diesel project, and I'm still pretty much a newb.
Any suggestions are appreciated.
Thanks
