We just completed our second 2.7 to 3.2/3.5 swap. This swap was to a 3.2 in a 2000 Concorde. We went to start it today and we have nothing. When you turn the key, the check engine light icon doesn't light up in the dash, so I don't think the pcm is getting power for some reason. The pcm isn't telling th starter relay to engage the starter. I have power going to the starter and the distribution box for the fuses and relays from the battery. I even checked for power at the box and it is present there. When I turn the key I do have some lights in the dash, seatbelt light and some others that aren't pcm related I guess. I'm wondering if there ispcm ground or something. I have very generic wiring diagrams that are not very detailed. Which wires or pins does the pcm receive power? Do you have any ideas? I did the swap the same way we did thefirst swap which was a 3.5 into a 2002 Intrepid and didn't have any problems with that.Thanks for any help!

If the new engine is from like a 2002 or newer, it's not directly compatible.

 

The motor isfrom a 2000 Concorde also.
