Default Fuel Pump ECCENTRIC...need inputs

Hi. What I thought was a case of fouled plugs ended up being a zero fuel pressure situation. Pulled the Carter mechanical fuel pump and inspected it but didn't see anything obvious (i.e. torn diaphragm, etc.). Motor is a stroked 392 from RDI with just under 11K miles.

Decided to poke a thin steel rod into the fuel pump cavity and noticed that I can rotate the eccentric slightly (maybe 10 degrees). Given all the friction associated with the valve train, timing chain, etc. I figured I shouldn't get any movement from the eccentric, correct?

I was always under the assumption that fuel pumps either work or they don't. I just don't want to have to tear into the front of the block if I don't need to. And if I do, appreciate any advice for doing same.

Regards,

-Dean
