Intermittent Starting Issue

Hello!

Thank you for checking out this thread, it's quite a wild one.


I am having an odd issue with my car that I am hoping to get some help with.



My car was in an accident, after it was repaired this issue arose.


Here is the issue.


The car will start and then die imediatly after....then it will just crank until i cycle the key then it will start and die again, its a very viscious cycle.

I took it to a local shop and they told me my DME was bad so I went ahead and bought a new one, while sitting bored at home I went ahead and swapped DMEs (no clue why, just bored - it had not been programmed) and noticed that it sounded healthy when cranking and that the immobilizer was kicking in, I went ahead and swapped the DME with my old one and BAM! the car started with no codes!

I was excited but also confused since this doesnt make any sense.

After the shop messed with it they gave it back to me saying they made no progress.


As of today I have done some troubleshooting with no luck, The car will only start after unplugging and plugging in the DME. It will start fine with no codes for the rest of the day, in the morning it will not start and throw out a ton of codes


P2095 - B Camshaft Position Bank 2
P2093 - A Camshaft Position Bank 2
P2091 - B Camshaft Position Bank 1
P2089 - A Camshaft Position Bank 1
U011E - Lost Communication with Throttle Actuator B
U0107 - Lost Communication with Throttle Actuator Control Module
U1136 - Lost Communication with Idle Speed Control Valve



Once I reset the DME and clear the codes they will not come back.

Help, I am running out of ideas
