Check engine light flashes(No reverse)

[Bilko]

Check engine light flashes (one time) after putting the sled back together(New motor). I have adjusted the TPS with a tool and still no reverse. This is driving me crazy. Any suggestions (Harness or bad ground) Thanks

TPS pigtail? Pull gently but firmly on the wires going into the connector....

Also look at the prongs on the plug of the harness that plug into the TPS sensor they're known for bending or cracking and I think there's an old post about soldering them to fix them.
