My jeep died and when I went to restart it I had no power. Battery is good, starter is good. I replaced the ignition switch and module but still no power. Some lights stay on in the stereo when key is off but when u turn on the lights go off
Do you

If it's an automatic, test the neutral safety switch, if it's a manual, test the clutch switch.

Just probe the wire where they connect then follow it down to where they connect on wire and if you have power at both ends then they are good. What engine do you have cause I looked up your year and that is what is supposed tobe there unless you have the solenoid on the starter. Or has been changed. If the test light is bright at both ends or if volt meter shows same reading at both ends then links are good and yes it could cause no power to coil. If you look at diagram you shold have power to coil form relay on red t wire when cranking it can be a module problem as well though but you need to check this out and return with engine size if not able to get coil power.
