2007 rubicon won't start everytime

I have a 07 Rubicon 78000 mi with starting issues , I've changed the batt and the starter also swapped around the starter relay. Almost everyday it does it turn the key and you hear a click one time it turned over a did not start. Any ideals ??

It's happened to my wife's 2007 Rubicon 2-3 times over the past couple of years. Typically she tells me her Jeep won't start, I get in and it turns right over and I look at her like she's got 3 heads. Maybe there's more to it.

Or if it's a manual, put it in neutral and try that. Could be that the safety switch is going bad.

I am beginning to think this should be stickied!!!
2010 Sahara- 0 issues till last week when starter would not engage!!
Took it to dealer yesterday and they looked at it and were also stumped!
They wanted me to leave it there and I said NO WAY!
So then hauled it back home and fixed it myself!!!

The starter works every time now!!!

Fused hot wire goes to button-- then wire goes from button to small terminal on solenoid!
Turn key to "START" -- then press button and starter works!!

It's a auto , I have wiggled the shifter and it works sometimes but one time it turned over and tried to start then shut off. I would think if it's the neutral switch it would do nothing at all.

I put a grounding cable from the batt to the alternator and it seemed to work. Wish me luck.

Remove your ground and clean all the factory grounds. Shine em up on both ends. Then try to start.

There is a write up some where with someone that had the problem. They advised like someone above to run a cable from the negative battery terminal to a ground bolt near the alternator. I think they ran 4 gauge wire and said no problems since. I personally have not had the issue.

2007 No Intermittent Start

Had same problem with my 2007 JK. Trouble was with the (WCM) Wireless Control Module ( Keyless Entry) When this is changed the keys need to be reprogrammed. Has been good since.
Good Luck

I had mine to dealer last week and the tech found a broken wire between relay and starter solonoid. He replaced said wire and starter works every time now!!!

I have a 2007 Rubicon as well. I've been dealing with the issue for the past 3 months. So far the dealer replaced the magnetic box behind the key switch, the battery and starter--still having the same problem. However, when the no-starting issue reappears, I put it in neutral and it starts every time. Today they're replacing the range sensor. Hopefully this will cure the problem. I do a lot of hunting in the deeps woods and if this doesn't work, I may be forced to purchase a different hunting vehicle. Already invested a lot of money in factory lift kit, warn winch, HID light etc, etc. We'll see what happens. Have a good day

Should have put a floor plunger in instead and you could have had a setup like the old Willis Jeeps with the floor starter.

Easy fix== see post no 5 above. Only thing is with this system; there is NO safety lock out of any kind..... I.E. one has to think before engaging starter.

On my jeep I have replaced to following with factory parts to no avail at fixing the issue
-Starter
-WCM Module
-TIPM Module
-Battery (Optima Red Top)
-Injector Harness and #4 Injector
-Hood Pin Switch
-Ignition Switch
-Crank Sensor
-Ran Secondary Ground form Starter to frame rail with battery cable

And it has been towed to the dealer 4 times and they mysteriously cant get a duplicate of the problem but yet refer parts that could fix it

Thank the good Lord--I think we got it licked. Replaced the Range Sensor last week before my Moose hunt. Drove and started every time. Prior to that, whenever the jeep acted up (almost daily) and wouldn't start I would put it in neutral and it would start every time without fail. Now that the range sensor was replaced, the vehicle has started ever time. I think I'll keep it afterall. By the way, came out with a 850 lb bull moose, rack spread of 4 feet.

You need to open an account on a photo hosting site( I use photobucket).
Then upload your photos to there. When you mouse over the thumbnail; a dropdown menu will show-- click on the link that says copied-- then go back to the wf page and paste!! Maybe some one better with words can also chime in here and help out. There should also be a sticky here in the forum on how to post pics that might be more help!!
