M915-M920 Cummins PT Pump No Throttle Response

[Thomas_G]

Anyone ever have an issue with their PT pump not responding?

I put a brand new pump on, new tanks, lines and fresh fuel and now 5 months later truck will start, only idle and shut off normally.

replaced filters (inside pump and on back) which looked good, throttle shaft moves but no response.

also who knows of a good Cummins Fuel Pump Repair Shop?

Aneroid valve is stuck.

Member @royalflush55 has some pumps in the box

Rebuilding a pump isn't pricey by shops. Easy pump. Have them put an aneroid block off in. You don't really need it. It just limits smoke on take off.

Circled in the picture is the line that runs to it.
