My roommates' 97 TJ threw a couple check engine lights, then stopped running entirely. The hint was that the CEL **wasn't** coming on when I turned the key. Capacitors had leaked and dissolved the flex PCB, the 5v regulator circuit was straight up gone! I tried repairing it with new capacitors but there just wasn't enough left. As a hail mary before spending hundreds on a used ECU that probably has the same issues, I tried two $0.50 5v regulators from Amazon and it worked! The check engine light even stopped tripping and the engine runs better lol. Not a bad fix for $1. Screw Chrysler for using shitty capacitors, and why is this this even a flex PCB?? Anyway I smothered it in 3M Quadrack hot glue and resealed it with RTV before bolting it back on and sending it around the back 40.
