There is at least one ECM fuse in the fuse box. That would be a good place to check. The fuse box is under the left end of the dash. It will swing down if you release the tabs. (Not a requirement, to get to the fuses, but it helps.)
The ECM itself is behind the console, mounted on the rear firewall, between the seats.
I wouldn't be surprised if something got in there (or somewhere in the car) and chewed through some wires.
To remove the console, first remove the clip from the front of the shifter handle. It looks like a big staple. Comes out from the front.
Once that comes off, you can pull the T handle straight up, off of the shifter.
Then remove the two ashtray inserts, and remove the four 7mm hex screws. Lift the shift console up, and off of the shifter. As you are lifting the shift console, there should be two tiny ashtray lamps, plugged into the bottom of the console, as well as a gear indicator lamp. Twist and unplug those sockets from the shift console.
Once that is out, you will see two 7mm hex screws holding the front edge of the rear console section. Remove those screws.
Open the storage compartment between the seats. There will be two more 7mm hex screws in the back of the open compartment. Remove those.
Also remove the two screws that hold the cigarette lighter bracket to the console.
Once those are all removed, you should be able to lift the rear section of the console up and out. Let the lighter assembly fall through the hole as you lift the console out.
