Damn it feels good to be back running again! :up: After extensive troubleshooting with everything pointing to the EHC I gave in and went for the WirePlus replacement. Jake swapped it out today in his shop and once everything was buttoned up, I turned the key on, hit the run button, mashed the start button and she fired right up. :2thumbs: When I first started the process of running down the problem I hoped that I could find some kind of connection or shorted wire problem but there was nothing wrong with the wiring. I want to thank those who chimed in to help with troubleshooting ideas.
I started a thread a few weeks ago to track the troubleshooting progress but in summary my '08K9 began having intermittent problems starting and eventually wouldn't start at all. Also, the left front blinker wouldn't work. When I checked all wiring and controls and found no problems and couldn't locate a good EHC to validate my suspicion I decided to replace the EHC. Now, everything functions properly again.
Kudos to Jake - BDMRIDGEBACK.
