Archived 1st gen died while driving. Won’t start

[DMcLeod]

92 w250 driving along lost power over a few seconds then died. Only cranks, no start now. I have suspect air leak in fuel line as it will not start after sitting more than a day without bleeding air. Related? Can anyone help with other quick checks, electrical, fuse, etc. that will cause no start.

Suspect the fuel shut off solenoid on the back of the IP. Check and make sure you have power to it with key on and you can hear it work. Also check and make sure you have fuel to the IP thru the filter, filters can plug, LP's go bad.
