So my 08 malibu will not start or even crank. I have checked basic stuff.
battery and terminals is good.
Starter has been tested all good.
Odb trouble code comes up u0100 lost connection with ecm pcm.
I'm thinking it's a common issue with fuse box copper wiring shorting out in heat as car was sitting direct sunlight at q03 degrees.
message on dash is power steering, service esc, service traction.
thinking about replacing fuse box as its common issue.
any ideas or suggestions would be great. The only other thing I can think of is ignition switch issue. Any ideas would be helpful
