Ok, so I have an odd problem I’m dealing with. Need some different opinions/input.
I have a 2009 JKU with LS swap + 6L80e tranny. Been running perfect for over a year now. I decided to install a Genesis dual battery tray and hit a snag during install. Once everything was installed, go to start and get ACC power (lights, radio, etc.) and no start or starter “click”. I’ve installed 2 brand new Odysee batteries and Here are the symptoms:
- no starter click whatsoever.
- turn key off, turn back on and no ACC power this time. Totally dead...
- disconnect battery and get ACC power again with no starter crank
- oddly key fob no longer works (lock, unlock, or auto-start)
- put meter on starter with no power to starter at all.
Here is what I’ve done so far with no joy...
- tested batteries and both are good
- re-installed old battery as it was and same result
- replaced key fob battery
- cleaned terminals and reconnected
- checked all fuses as well as pulled all fuses related to starting sequence to reset ECM, etc. (many threads on the security system resetting with pulling fuses to reset the system)
- put a scanner on Jeep side, no communication. Put it on GM side, no errors... shows normal.
- tried starting in N to rule out neutral switch on trans.
My thoughts...
- I may an have a ECM failure.
- The key has lost its programming to the Jeep. I’m thinking this because the lock/unlock/auto-start function stopped working completely. However, if the key has lost its programming, I am curious as to how the ACC power still comes on?
What’s my problem? Any ideas?
Thanks!
