I have a 2000 S80 T6 and would like some help. It started about month ago it would stall (driving or stopped) it did this about 5 times about two weeks ago the STC Service Required light came on. On Monday I went to start and it would just turn over (not hitting or anything). Here's what I done (as far as test)

Checked fuel to fuel bar (OK)
Pulled two plugs (both dry as a bone)
Tested coils with spark plug (no fire)
Checked all fuses (3 Panels)
So it seems that i'm getting fuel to the bar but the injectors are not pulsing and no fire on coils.

Can anyone tell me what to check next?

 

Crank sensor and/or cam sensor.

 

Does anyone have a schematic of a 2000 S80 T6 or know if there’s one posted on the forum?

 

I tested the crank sensor and at 2K it reads .122, does anybody have the scale it should be or know the reading.
