S70 Starts for 3 seconds, then stalls (green lambda light)
 

Hey all,

The other morning the car wouldn't start. I figured it was because of the cold, and tried when it was warmer. It still didn't start, and I ended up draining the battery trying to start it. I charged the battery to full - and I changed all the 5 sparkplugs it sounds better, and it starts but after about 2 seconds it stalls.

There is also a green Lambda light on the dash, from what I have read this could be a variety of things. I checked the front 02 sensor and it looks very new like its been recently replaced.

I have no idea how to fix it - I was wondering if maybe an immobilizer was kicking in because I had the battery out for so long and stopping the engine?

Has anyone else experienced the green lambda of death?
