Broken Engine Ground
I was under the jeep today and noticed a ground strap just hanging. I have had a few no crank issues lately and I think this may be the reason. It looks like its coming from the pass. side firewall. Where is it supposed to be attached to? I tried searching, any one have a pic or diagram of the engine grounds.
TIA

I am interested too. I have been having no start issues over the last month. Starter just clicks but doesn't turn over the engine. On the second through fourth try it starts normally, not a slow crank either. All lights stay on so I doubted it was the battery.
I took it into the dealer and they replaced the starter but I still have the issue occasionally. Sounds like a loose cable to me so I tried to trace the ground and lost it when it goes behind the motor. I replaced the battery yesterday to see if maybe the battery may be developing a short.

I bought my 07 a few months ago. Same problem. Took it to the dealership and they put new starter and battery in but problem was still there. Put the jeep up on the lift in shop and found no grounding strap at all. There is suppose to be a ground from fire wall to drive train, then also engine to frame.
All's I did was run a ground wire from my battery to the drive train (lower bellhousing) and have had no problems since.
It's been 3 months now, Jeep starts everytime. So far so good.

There is a ground strap, flat bare woven wire, that goes from the passenger side engine block (behind catalytic converter down tube) to the hood, I believe this is what is loose on yours. It comes up along the firewall behind the battery tray toward the center of the vehicle side and to a bolt on the hood directly above it. This has nothing to do with starting as it is just a ground strap, not a cable. It is there from my understanding to prevent static electricity from building up from hood vibrations that could cause electronic(radio) interference.
The ground cable goes from the battery negative terminal to behind the engine grounding on the bellhousing. There is a second cable from the same terminal that goes to front passenger fender(body ground).
