Sounds like something is disconnected or maybe the battery died? Can't think of why the HUD would prevent the car starting, double check your wiring if that's correct. Disconnect the HUD and see if car will start. Not much help I know, when I installed the HUD in my 08 the wiring was simple, I would suspect a connect has come loose.

I triple check. everything about 5 times now. The only thing that will cause the car to fire up is the HUD Class 2 Serial Data to be disconnected. The six loose end coming from the Blue connector (HUD switch) and the brown connector (HUD projector) that is tapped into the gray and black IPC connectors are...
  1. battery
  2. ground
  3. vehicle speed
  4. engine speed
  5. IP lamp supply voltage -2
  6. HUD Class 2 Serial Data
everytime I discount only the HUD Class 2 Serial Data, the car will start.

Well that would make me think it's the HUD unit. Do you know it is a good working unit?

I don't know if it was working or not. I got it at a buddy shop it came out of a wreck vette. I'm hoping theres something I'm missing.

Sounds like you soldered the connections. cut soldered joints and wire with the red taps that were provided...
