I can finally put this one to bed!
Got the pressure tester. Hooked it up and turned the key to "ON." Jumped right to 49 PSI and after the pump cut out it stayed right at 40 PSI. I was upset because I thought I finally figured it out. But fuel pressure is perfect. Checked the regulator and it was working, too.
So I started giggling wires under the hood. After unhooking and reconnected the wire from the ICM that goes through the firewall, it started right up.
I drove home and started disconnecting and cleaning all my connectors the next day.
Hooked everything up after drying.
Checked for vacuum leaks--finally--but found none.
Started right up and drives like new now. Idle is butter and it revs up completely.
Let this thread be a lesson to everybody with a 22 year old car: start with the easy stuff. Don't shotgun parts like I did. You'll feel like a broke idiot.
I appreciate the help, guys.
