I have a 2014 CTSV sport with a blown head gasket. I purchased a another engine from a 2019 V Sport and made the swap. Everything looks normal when turning on the ignition but engine will not turn over or make any sound not even a click. Hitting the start button a second time turns the instrument cluster off but with no Cadillac shutdown logo. I used the harness that was on the donor engine. Should I have used my old harness? Donor engine has 8k on it. I'm 10 days into this and kinda frustrated. Any suggestions, thoughts?
