No Crank. Ignition? Wiring? 🤷🏻♂️
2013 JK auto RHD
No crank
Crank but no start when jumping starter with key in the start position.
No power on purple wire with key in start position. Not sure if this is correct or not. Is this correct or is this my problem.
My Jeep has been sitting in my carport dead for a month. I have vigorously combed this forum as well as others and more YouTube vids than I can count. Any and all help appreciated. I also have access to service manuals they are just huge and some what overwhelming. So again thanx in advance for all help.

Any codes being thrown? I believe with the 3.6 JKs, maybe all of them the key just tells the computer to crank, it will make it difficult to diagnose. Get the codes read, try disconnecting the battery to reset the computer. If the battery is old try a new one chrysler computers do weird shit if the battery is poor.

I changed the spark plugs which I think will take care of some of those as well as reconnected the coil pack plug that was loose. But Jeep has not cranked and ran since I did those things. Not sure if that’s relevant to the codes.
Also replaced bad battery with new battery.

Also found today that k3 relay is good. But only has power at pin 30. Can use a jumper to go from pins 30 to 87, and get a crank, but not start situation.
