I just got done putting a new cylinder head on and it cranks but won’t start, it has no spark and the scantool will not communicate with the car. It won’t scan the engine but immobilizer has code a0b3 (starter motor terminal 50)

check wiring around battery and fuse box area and the small wire to the starter solenoid
