So far we have these issues:
- Starter will not operate
- Gauges inop when ignition switched on, cluster lamps do work
- OBD port inop/cannot communicate with PCM via scanner
Battery and ignition switch have been replaced.
When you switch the ignition on before taking it to start, can you hear the fuel pump kick on for about two seconds?
Have you checked all your fuses to make sure they are good, no corrosion is present on their terminals, and there is power getting through them?
Does jump starting the Jeep from a running vehicle make any difference?
Try swapping the horn and starter relays to see if the starter will then operate.
If you have aftermarket bolt on battery cable terminal ends, they're garbage. Factory style cables with sealed terminal ends should be used.
Ensure the gang ground point at the right rear side of the engine block and all the cables going to it is thoroughly cleaned and tightened.
