So today I was out and about and my dash lit up like a Christmas tree and my 2007 JK shut off and wouldn't restart. I checked every fuse and went through all my grounds and still no start. It is not even cranking but I do hear the starter relay clicking. Did a ton of searches here. it is not the sentry issue. My power door locks still work and the sentry light goes off after a few seconds of key on. I have a stick so I did tried to start in 4Low to bypass the clutch switch. I also tried my spare key. I pulled battery and got it checked, it is only a few months old, it tested perfect. I have no power to the diagnostic port which concerns me.

Thursday I had all the O2 sensors replaced, nothing else has changed. I was talking on the CB when this happened. Jeep has 140,000 miles but well maintained. Any thoughts on this? Unfortunately it will have to sit awhile before having it towed to the dealership to allow me to save us the funds.

 

07 here as well, Only times my jeep has never started it was a battery issue.

Two times in ten years, no matter what I thought it worked for me. Some where you're losing the flow, which is crazy. You've checked all that seems possible as well. I did my starter for no reason couple years back.

Did you get a solid test on your other components?

 

Ya Battery was perfect, all fuses good. I am about ready to pull my aftermarket radio and the interface adapter. I am putting everything back to stock. then it will go to the dealer.

 

I've seen something similar before and it turned out to be a bad TIPM. Not saying run out and buy one because they are expensive, but won't be surprised if that's what it turns out to be.

 

I really started looking at this and after 10 years of weird stuff happening, I'm thinking it is related. Had dash light up when driving, door lock work when they want. random codes that show up and disappear to never be seen again, radio coming on when opening up the door, windshield wipers just coming on, horn going off. All this has happened over the years and I really never thought anything about it as it has been intermittent. Last night when i went out to my jeep, I noticed my dome light led bulbs were glowing, pulled them and will get stock replacements. I also have a aftermarket radio installed with the PAC interface adapter. Will be pulling that as well and putting the factory radio back in place. If I can get this running, might be time for a spod to route my electronics through the jeep safely. I found a mopar TPIM at moparpartsonline.com for $200. I may give it a try. If all fails it has to go to the dealership anyways.

I had a TIPM issue with my 2011 Chrysler T&C and Jason at VV was able to walk me through the issue. I explained to him what I was seeing and he was able to confirm similar issues being caused by the TIPM. I bought one of his test / bypass harnesses which worked great until it started getting cold. Ended up sending the TIPM to them for repair. They turned it around the same day. I was without the TIPM for one week, but all of that was shipping time so that could be expedited for $$.

Good luck!

 

I went through the fuses again with a meter and I found that m28 was bad. This feeds the PCM. Replaced and it fired up. Plugged in my trail dash and it blew. HopeING the superchip is bad. I will be taking the jeep in for a couple of recalls. I guess I will find out if the obd is blowing the fuse due to a short in the pcm or wiring. I'm sure they will need it to scan the system.

 

I know this is really old but did you ever figure out the problem. Same fuse is blowing for me as soon as I plug in trail dash.
