When you goofed with the oil pump did you fill the gear cavity with Vaseline so the pump would prime? Did you pull a v/c and spin the oil pump with a drill and see oil at the rockers? If not I would pull the pump back apart, pack it with Vaseline and put it together, and spin it to see if you can get oil up in the rockers.
Then we can move forward and find someone local to you who has the cam sensor tool or use a meter to set the cam sensor.
Get the oil pressure right first, it ain't going anywhere with out oil pressure.
