I had a similar problem but manage to jump start the car and it started by itself several times until now all electronics work but the screen shows the AMT as being in 1 no matter how I have the speed stick.
I also read about a pink cable and ground connection but nobody has been able to pinpoint where these cables are ...
Starting Problems
The most common starting problem is when it goes through all the preliminary starting sequence but then the starter motor fails to engage.
This is usually caused by a poor connection at the thin PINK signal wire which connects via a spade terminal on the starter solenoid.
Try sliding the spade up and down a few times to improve the connection. Long term you need a new spade connector fitting or tighten the existing spade but this is a bit more tricky as not much space to work. There are other comments about this elsewhere in these blogs.
