I would guess you have the small drive gear installed incorrectly on the crank. Slide the gear out a bit, set the pistons to TDC, and turn the oil pump gear wheel so the alignment pin for the ignition is at 12 'o clock (straight up). Now have a look at the drive gear and re-adjust the drive gear as needed. Usually, but not always, there is an "O" stamped on one side of this gear and it should align to another "O" stamped on the crank itself.
