motor swap car won't crank p0600 code
 

Ok I had an alroad 2.7t 02 I was rear ended car was totaled so I pulled the motor and bought a sedan 02 2.7t a6 with a blown motor did a full motor and trans swap still auto just didn't want to pull the trans off the motor can't get the car to crank at all I get clicking in the engine bay like stuff turning on but no crank getting 3 codes p0600 p0113 p0118 is this just an ecu problem that is not communicating with the motor and needs to be reprogrammed or what else could it be grounds look good unless I'm missing one ecu and wire harness stayed with the sedan
