having huge problems, for the last 6 months I have been without a truck. Unfortunately it was a the mechanics in working condition but sat in the yard the batteries died. my problem now is the flashing security light on the dash not allowing the truck to start. it cranks over keyless entry worked all electronics work but just won't start. whole truck has been re-earthed and checked over. I also can't connect to the truck through the obd port there is power there but no tools are able to connect have had many different tools including dealer tools try. I'm really stuck at this stage and don't know weather Its the immobiliser or shot ecu or even a tipm, any input is greatly appreciated.

 

You have any luck with this? Have you checked every fuse in the box?

 

Never run into it with a dodge but I know with chevys when I try to hook in my scanner and says it can’t communicate it is always the cigarette lighter fuse every time which is often at my shop
