I don't not have the actual part number but the description of the part its correct...park/ neutral sensor switch or whatever the official name of it is, but more then likely if bumping the shifter worked then its most likely the problem.
even when the switch is functioning properly it will only start in neutral or park...nothing else. I'm trying to find a write up for the switch replacement...will edit with a link if I can find it

 

Thanks for your help, anyway...

 

It is a neutral safety switch. It should be on the column. I wired a chevy truck straight when I had problems with it.

 

Can you explain this better??

 

Just bought the sensor... After the change I will write what happened...

 

Safety sensor changed on friday...
Problem solved!! It worked every single time I turned the key!!

Thanks!!

 

My not so old problem is back...
Few times, when I tey to start my JK, it just do not start. It is everything normal, but the engine do not start... Then I try sometimes and it just work...

Batery is ok,
Start engine is ok,
Safety sensor is ok
Ground is cleaned...

What else??

I'm starting to think about exploding my JK...

If anyone want more details, just ask...

 

Nobody have a nice idea? And a bad one?

 

I was getting the Click-no-start problem about every 20 starts. Took it by mechanic and he said the battery checked out but It was most likely not enough battery. I bought the mack daddy he had for about 130. Got home, same problem.

I called the dealership and he said he could fix it for about 160, run a new ground wire and some other thing I cant remember. He said he didnt know what was causing it, but after these two fixes nobody ever came back. So it seems there is 2 small issues that cause it.

Kinda sucks because you always have that thought in the back of your head, "am I gonna get stranded out here?"

 

Super70, my problem is a little different... But I will try your solution, and I get very worried about my jeep no starting...
I dont have a click-no start... I have no click!! I turn the keynand nothing happens...
