Issue: No Crank or Start, more below...
Year: 2007.5
Engine: 6.7
Trans: 68RFE automatic
Mods: Full delete, RaceMe tuner running mild +40hp standard tune, Edge Insight CTS2 with EGT probe, Lots of suspension mods from Thuren probably not relevant other than there has been a lot of welding and plasma cutting done on the truck (possible electronics issues??). Some accessory lights but they are wired directly to the battery with relays except for the rocker switch lights which are tapped into power under the dash.
Owned the truck for 3 years now and it's been amazing until I took it in for an alignment last week and the mechanic could not start it after the work, dead on the rack. No history with the shop but they have good reviews although they did seem to struggle with what should have been really simple and then claimed a cam bolt was stripped and wanted to keep the truck overnight to order a new bolt. I agreed and late the next day is when the problem was discovered. Truck supposedly had the key on for a long time while they messed with the alignment and battery voltage probably dropped somewhat since I hadn't been driving the truck in a while before this and the Edge was plugged in. Still haven't figured out if they did anything malicious or it was just bad timing and from leaving the key on.
Active codes: U0100, U0141, C2202, C2206
Stored codes: B210D U0184, U0164, U01019 and repeats of the above active ones
The above codes are from their scanner. I plugged in a cheapo code reader and it didn't show anything. Plugged in my RaceMe and got CAN error#121 with no communication. Tried the Edge and it wouldn't communicate either. I have an x431 coming tomorrow to help with the diagnosis.
Any ideas on where to start? I did find a 2 year old thread on here of almost the exact problem and messaged the OP, hopefully he is still on here as the thread did not come to a resolution.
Is the battery voltage getting low with the Edge plugged in possibly a cause for this or some other random thing or does this strongly point to the shop trying some shady things with my baby that I need to really look into?
Thanks!
