The pump shaft is not going in to the dist this can be a real ***** some times. With to much pressure the pump shaft will rotate when turning the engine. The best way I found is lift dist and lightly bouce till it seats. Or pull dist reach down and move the pump shaft till it lines up. Don't start the engine with the shaft not seated will burr one of them then you are dropping the pan good luck feel free to hit me up if you have any questions. The FE engine is one of fords under rated engines
