Well I know its been awhile and didn't get any help from anyone on here, due to it being such a weird problem. Figured i would post the results. found the CEM was taking out the CAN bus. not sure why it started after i had the turbo out. but anyway. replaced with a junk yard module and it fired right up. After doing a search for CEM's on google i found a few post, q/a about how they can be a common problem. Anyway hope this helps anyone out in the future. Thanks
