Question 2006 Jeep starting problems

I'm new to this, so please be gentle. I have a 2006 Wrangler with 18,000 miles on it. I LOVE my jeep. Recently my baby has developed problems with starting. First start of the day is okay, but after that she won't turn over on the first try. As I speak she is in the shop, and of course they can't find a problem. Has anyone else had a similar issue? If so what did they find was wrong? Any help would be greatly appreciated.
Sandy

Hard to believe starting issues with milage, but anything can happen with the cold & moisture lately depending on your area.

Does it crank over... or does it seem slow to crank....

Would check the following:
Battery Cables secure to battery

Check fuses behind glove box

Check cables to the Starter then to make sure secure. I had an issue where the Neg. connector on starter would wiggle loose after sometime and cause issues. In my case I had power to everything, but would not crank. I end up having ro rub/clean the Neg contact on the starter solenoid.

Check plug wires to spark plugs & Dist. Cap.
If needed pull plug wires to see if getting spark, by pulling wire and holding next to spark plug, with 2nd person in Jeep cranking it over. You should see a spark and should be fairly bright.

Snwchris suggests all good things... I just want to confirm what you mean by it won't "turn over" after it starts fine in the morning. Do you mean the engine spins and the starter spins the engine normally but the engine just won't start? Or do you mean the starter just clicks when you turn the ignition key to the Start position?

When you put the keys in the ignition or open the door, do any lights come on the dash or does the dome light come one? If not check to see if the battery is dead or has a loose connection on the terminals.

I had this problem that the leads from the jeep were not tight enough on the terminal posts on the battery. This caused it not to start completely.

The starter does not just click. Every thing spins okay it just wont fire to the run phase.

Every thing powers up okay, dome lights, radio etc. I checked the battery and the pos cable was crusty. I cleaned and re-attached both. The dealer has had it for 2 days and says everything checks out okay on the diagnostics including the battery. Since I bought the Jeep on Friday the 13th I think I will go get a new Battery today. Idaho winters can be brutal and they do put in a brand X when they build them.
Thanks for the input

Thanks for the info I will check these things out. But sinse I bought my jeep on Friday the 13th, I think I will go get a new battery today. A good one not just the brand x they put in them when they are built.

There was a similar post the other day about trouble starting when it rains. I had the same issue.it was Ok when it was dry but a real tough start when it was humid or wet. I change the coil (plus normal tune up) and I haven't had any issues so far.

Since you say the starter motor spins the engine normally but the engine just doesn't start, I don't believe a new battery is going to help.

Sounds like the Starter spur gear is stuck or not engaging. If you have another person to help, have one try starting it and the ther person try tapping the starter solenoid to see if that helps release and engage.

Otherwise probably good chance that it might be the starter, NOT the battery.

Mines an 03 and still have original battery.

2006 start problems

Men same thing with my 06 TJ.

This is my 5th jeep and never had problems. This one has some issues. Less than 50,000 miles.

1. Issue número UNO

Starts when ever he wants. Terminals are new, battery is new. Key inserted and power is good. Turn key and nothing no cranking or nothing. Then I just press on the clutch and press on the brakes and nada. I do this a few times and then it just starts. So I go to work and park at the commuter lot. Sometimes I come back and it starts right away with no issues. But again this morning more of the same. Keys in the ignition press clutch and nothing, press the brake hard and nothing, move the gears to neutral and nothing. Release the emergency brake and do the drill a few times and then it starts. I have no idea were to begging.

2. This is really weird. When I bought the jeep it had a check engine light on. The system said cilinder # 3 misfires. Well the dealer replaced the battery and other components then the jeep ran great and so I drove it from Georgia to virginia with no issues. No engine light on but sometimes when I take off on first gear the jeep seems to be fuel starve and it takes a bit to take off. Same thing when I shift into second gear. Bad fuel? I don't know.

Your clutch pedal position switch is probably bad. If non-Rubicon, put the fuse in the off road slot in the fuse box. If Rubicon, it will start in 4LO, or you can jumper the switch.

There is not a neutral or brake safety switch with the manual trans.

Only other way to fix it is to replace the clutch master cylinder of which the switch is a part.

I was so happy with my new project.... Just go to the auto store and by a fuse to plug into the off road slot #20 for a bypass. well i did it and nothing. I read the diagram for the fuse box and it saids that #20 was just for spare. There was one in there already. I also tried to start the jeep on 4L and also nothing. I had to press on the cluth several times and all of the way down and after a couple of tries it finnally started. Back to square #1 and maybe just unpluging the circuit and jumping it may do the trick. Any other suggestions????

From the owner's manual:

Clutch Interlocking Ignition System (Non —
Rubicon Models Only)
Manual transmission vehicles are equipped with a clutch
interlock safety feature. With this feature engaged, you
must depress the clutch pedal to allow cranking of the
engine. To temporarily bypass this safety feature while
off-road driving (4L range only), which will allow cranking
the engine without depressing the clutch, follow
these steps:
1. Locate the Power Distribution Center (PDC) in the
engine compartment. Refer to “Fuse Panel” in Section 7
of this manual. (See page 305 for more information.)
2. Put a 10 Amp fuse in the PDC cavity (#28) marked as
Clutch Override.
NOTE: A fuse is provided in fuseblock cavity (f19 or
f20) marked as Spare.
STARTING AND OPERATING 187

You can download the owner's manual from Jeep.com

Jkp,

It worked right away, however, the display shows that the vehicle is in 4H. Is it?

Layrider- sorry I jumped all over your post. Your post was very helpful. Hope your jeep is running good. I followed the steps and mine now starts without pressing the clutch or brakes. However, as I just mentioned, the 4H light is on the display.

You're only in 4H if the lever is pulled back to 4H, that is strictly a mechanical linkage.

I can't imagine that the light would come on due to overiding the clutch switch. Mine is a Rubicon, so it does not have the fuse bypass option, so I can't check this.

Move the 4WD lever back and forth and be sure it is completely in the 2H position.

My Jeep did the same thing today.. although mine is an automatic unlimited. It was running fine all day and I came home from work and when I went to leave again it turned over started, idled rough and cut off. After it did that it would not start at all. The starter will turn over but the engine will not start. Anyone know what it may be?
