1966 327 AMC Fireball oil pressure

[chefs1953]

Hello,
Just started my 66 327 amc fireball.
Rebuilt 7 years ago with solid lifters, less than 25 hours.
I had great oil pressure before winterizing 3 years ago, now zero
Checked gauge, changed, checked at engine, none, blew air down line, crankes and no oil came up.
Do I need to pull engine for a new pump? Pull distributor to check if gear spins free.
I am lost, any idea will help before I pull engine.
Thank you
Dave

I'd be inclined to use a known good mechanical gauge before doing anything else...also worth checking to see if the rotor inside the distributor is rotating, the oil pump should be spinning...if not, its likely something broke internally...
