My Volvo 850 GLS 20V went out suddenly during the ride. No more gasoline, no more sparks. The pump relay is no longer controlled. On the 15 there are 12V, the pump runs when bridged. So the 31 and 31b are gone. I think the mass is missing from the ignition coil. The fault memory did not show any results on the 6. Has one of you ever had this shit?
