Take apart the cluster panel and clean everything, most likely have a LOT of dust in the connectors in there, might have a look at your ignition while you are at it anyway, make sure the connectors there aren't dirty or loose.
Actually use dielectric grease, which is non conductive. You do not want any type of contuctive grease (never seize, or any grease with metals in it) in connectors as it will short from one pin to the other in the connector.use conductive grease on connectors
@06softtop Neither type of grease is the answer to this problem. Using a dielectric grease just prevents corrosion and helps protects electrical connectors, it's never a cure for an existing electrical problem.Thanks i'll do that tonight, then see what happens
Note the above edit to my post, I added some thoughts after the earlier comment about the dielectric grease.Where would the dash ground wire or strap be is it under dash somewhere

Edit: You have replaced my first two guesses, the ignition switch actuator pin and the ignition switch. At this point it is starting to sound like the problem is inside the Power Distribution Center or at the connector leading to the ignition switch. The fact the starter only works when the Voltmeter indicates 12 volts leads makes something in the PDC or the ignition switch connector seem to be strong suspects. Especially that you don't see power to the starter solenoid's small gauge wire which comes from the starter relay inside the PDC.
If it were me I'd be looking closely at the wiring inside the PDC under all the relays inside the PDC. The wiring leading from the ignition switch would be of particular interest since that wiring also provides power to the PCM that turns the voltmeter on in the instrument cluster. There's some commonality there for sure.
When you replaced the ignition switch and actuator pin did you closely look at the wiring leading to the ignition switch connector? And at the ignition switch connector itself?
still having no crank issue lastest changed camshaft sensor, now when in the on position hear the IAC clicking and still fuel and battery gauge don't move, so looking for where to look that control those gauges causing a no crank issue
My 2018 jeep Sahara no crank no start and everything came on. Replaced battery and TIPM and didn't work. After a year of dealing with it we found it was the TIPM, replaced it and haven't had a problem since.still having no crank issue lastest changed camshaft sensor, now when in the on position hear the IAC clicking and still fuel and battery gauge don't move, so looking for where to look that control those gauges causing a no crank issue
