The alt and fuel solenoid fuses are reading 0.55 volts on the multi-meter.

I don't know squat about John Deere but I know that Diesels with a HPFP can be very sensitive when it comes to filters and filter housings. I'd check there, Thoroughly, and work from there. Diesels require three things to run - Fuel, Air and Compression. The HPFP (HighPressureFuelPump) is a wonderful invention but it brings certain headaches with it. It's why they go for $2,700 new. On your tractor

Make absolutely certain you're running an OEM fiter and check the housing for cracks or leaks. I've seen more problems with aftermarket filters on diesels than almost anything else. Except for maybe the emissions garbage, which you shouldn't have much of anyway. If at all.

Good luck.

Thanks, I think that I have narrowed it down to not getting voltage to my fuel shut off solenoid. Possibly a bad ground or connection. I’m just having a hard time finding the culprit.
