HELP - 1991 Jeep Cherokee Laredo 4 X 4 Engine won't start

If I remove the Air Filter into the throttle body and pour a bit of Gasoline, the engine starts and STAYS running...but the momentr I turn it off, If I leave it OFF for more than a minute, the Engine will not start.

It's almost as if I gotta prime the throttle body with fuel to get it going.



When I pour the fuel directly into the butterfly valve, after I crank the valve open a bit by hand...If I then crank it, it starts and stays running.

Does sound like a fuel delivery issue rather than the crankshaft position sensor since it does start and run if primed
