Like it says I swapped an 05 S/C engine into an 04 n/a car. I left The engine harness on the S/C engine and unplugged the harness from the relay box under the hood. I checked the relay boxes and they were identical according to the fuse/relay charts. Swapped the entire cradle, engine, trans, harness and PCM from the 05 S/C car. From everything I could find to read up on, I thought it was a plug and play. Evidently I was WRONG. Everything plugged up fine but when I turn the key on I can't hear the fuel pump turn on. Turn the engine to start entire dash goes out (can't remember if that's normal) but nothing happens. Can't hear any relays. Nothing. SO... HELP!!!!
