First heck the A6 socket. A6 is ignition.

Second, I had no start situation. Had spark, fuel and compression. Everything you need but still no start. A6 had 314 - bad cam sensor & 214 - speed sensor. Both codes just product of no start. (If you have spark then cam sensor good)

Basically the solution (from my volvo indy mechanic) was to grind the starter until something happens. Took about 1 minute before it sounded & felt like anything was happening - like maybe 1 cylinder catching and another 1/2 minute (1.5 total grind time) before it was running on all 5 cylinders and I could let off the starter. Goes against what we've been taught, but worked!

Make sure you have well charged battery and 'dry' the plugs. I put in new but mechanic said he uses propane torch to burn off any fuel/oil residue.

Good luck!
