Q: Car won't start - replaced torque converter. 2005 Ford Expedition

Okay so I replaced my tq and when I went to start it to get the fluid through the system it wouldn't start. I found that the drivetrain was locked up (wouldn't turn by hand) so I read some forums and foud that the tq was not seated all the way and that I probably cracked the pump housing. I ordered a new pump and installed it and made sure the tq was fully seated (went back aprox 3/4 of an inch past where I had it the first time. Now the motor turns over freely by hand but it still won't start (starter engauges but doent crank). I replaced the starter figuring I might have birnt something out in the solenoid but still does the same thing. I checked the fuse and it has continuity, I checked all 3 wires from the starter as far up as my multimeter could reach and they all have continuity but I couldnt get right up to the battery terminals. The starter I bought was a reman, should I swap it out for a new one, try replacing the relay, or try replacing the starter harness?

My car has 120000 miles.
