So I recently dropped my motor to do the f23 swap. I have the entire harness hooked back up and when I go to jump it to start it because to battery is dead it keeps popping the crank shaft position sensor relay. (Side note, I did not unhook the crankshaft position sensor when I removed the motor) with that being said, I'm grounding it to a different nut instead of the shock nuts/bolts. I didn't see any other relays go off at all. What could I have hooked up incorrectly and what else could be the issue?

 

Where are you now grounding the cable you are saying you moved to a different mount location? Any possibility it isn't making good contact? People on here have access to electrical diagrams that may help in diagnosis so hopefully one of them chimes in.

 

The harness is grounded to a different spot on the transmission now, ground seems fairly tight. When I go to jump it I'm grounding to a nut on the body. Could be likely it's not grounding properly in either place. An electrical diagram would help tremendously that way o can double check all my connection
