Fwiw,
anybody that
asks if they can swap engines in a computer controlled car,
should not even think if it!!!!
Get a 3.8 from the junkyard.
Imho, it's a ZILLION times better than the flaming POS short-star 3.5 engine with it's typical CR*P GM head/bolt design problems.
The 2001 has an AIR system.
You also don't have the correct ABS for a 2001 ECM. Yes, they ARE MARRIED!
And, so many other problems.
The ECM/BCM must talk to each other. They both control EVERYTHING!!!!!!!!!
As I said, *anyone* that asks if they can go an engine swap, should not even think of it.
Go get a pre '78 GM/Ford car. Swap all you want.
