Welcome to the forums.

I am not sure if your saying that the jeep wont start until the check engine light comes on or goes out? Does the check engine light stay on after you start it?

Get an OBDII code reader, and get the code(s) out of the PCM, and then come back.

with OBD 1 you can get blink codes, I would start there. Has ANY electrical work been done lately? Did you have an aftermarket radio installed? Something electrical has shorted out.
