I parked the 310G gas back in October, and everything was fine. I started it up Monday, and no oil pressure. I took the line off at the block, and nothing is coming out. I tried pumping oil down that fitting thinking maybe the pump needed to be primed, but still can't get any oil pressure. When I used it before, sometimes the oil pressure would be slow at coming up, like it had to fill the filter back up. I checked the oil, and it is almost full. Does anybody have any idea why this would happen? I thought about dropping the oil pan to see what I could find, if anything. Thought maybe somebody here might have a clue to what has happened. Thnak you in advance!!

I had the key that fits between the drive gear, and the pump shaft wear off once. Sounds like you had better drop the pan and do some hunting. DK

The oil pump has a floating oil strainer. It is possible that it has separated at the pivot point or the float is stuck (cocked) above the oil level. I don't think the above is very likely but is possible.

The link is a VA manual for the 124 cid engine but has the same type oil pump pickup. Click on page G2 J2.

I already did that. I took the oil filter off, and nothing there either.
