When a jeep (or any vehicle for that matter) sits for any length of time, the little check valves can either dry out or some of the particulate may keep them from sealing. The jeep has 6 of those little check valves in the pump if I recall, and the failre of even one will cause the pump not to pump. I found that by wetting the pump with some fuel (or priming the pump would be the better term) the pumps would normally work again.
When they were selling the M38A1s at auction in the mid 80s, I got one jeep with an almost brand new engine for only $1100 because they could not get it to run during the auction. A bit of gas from a squirt can into the pump quickly cured that and it was a beatiful running jeep. Replacing the stale gas made it run even better.
