Intermittent starting issues

[Warrior II]

I have a 2006 H3, It won't start and keeps cranking.After 10 minutes it starts. It happens from once a month to twice a day.When it does run,its fine no stalling or anything.I have been to dealer with this problem four times. They tell me since there is no service engine light on they are un able to fix problem.
Can someone Please give me direction to solve this matter?

Had a similar problem with my old H3 and the fuel pump was the culprit. I had to crank it for two or three minutes to get it to start. It was putting out pressure, but not enough. It didn't happen all the time and every now and then would start normally. The fuel pump was replaced under warranty and I never had that problem again.

Do you have a remote starter installed?

[Warrior II]

Thanx for responding. I do not have remote start. Also, I'll tell the the dealer about fuel pump but it won't be covered under warranty if pump still works.
The only other thing additional is that the security icon light came(pad lock with key) on for a few hours then went off twice.

It could be your battery...

Be certain to remove your key whenever you park even in your own garage.

Thanx for the responses, Im going for a new fuel pump and let ya know the outcome.By the way, battery is new. Fuel pump relay is new.
Can any one recommend headlight bulbs?(H13) I want to go a lot whiter but not HID. Thanx

I just had what sounds like the same problem with my 2006 H3.It would start and then just shut off.Would turn the key and nothing.Waited 5mins it would start,run fine, then stop.Then when it started it would run fine for days then it would do it again.Took it to the dealer they ran test and it was the computer which is covered under emissions for 8 years 80000 miles.They replaced for free now everything is fine.Hope this helps.

I'm having the same problem on my 2007 with only 31,000 miles. It cranks but won't turn over. I wait about 5-10 minutes and it starts. I brought it to my mechanic and when he hooks it up to the computer it doesn't show any codes. I'm bringing it to the dealer saturday as I have a few more weeks left on my warrenty. I love my h3. Its a great truck, but if I can't get this problem solved soon I'm going to seriously consider trading it in.

I had this same problem. Finally took it in to dealer and they replaced the ignition switch/assembly. Said it had to do with the alarm system and the engine shutting down the fuel. After around 10 minutes it would start again.

At first I thought it was my gas cap not sealing properly.
