CM871 Not Starting
Ok so I have a 2011 Prostar with a ISX CM871. I picked it up in Indy and ran fine until I hit Texas. Was a little hard to start in Texas but started on its own so got it to Vegas. In Vegas it wouldn’t start on its own had to use some ether.

Now its not starting at all. It will run on ether only. I pulled both filters and replaced them they’re getting fuel.

Somewhere from the filter to engine is the problem. Primer pump is working since my filters are full.

Where can I start looking for the issue at? Could it be the fuel shutoff solenoid? Im not thinking its the fuel pump since I drove it 1900 miles and when it started it ran fine.

Also does anyone have the part number for the 2 pressure valves in the fuel pump housing? International wouldn’t give me the part number. Its #25 and #37 in the diagram fp107ga
