1979 930 electrical question
Trying to learn how my 1979 930 works (or doesn't) compared to a '88 930 I recently sold. I have never owned this early a model so wonder what preceded later 1988 ECU/DME controls. I am having a stalling problem and trying to find the gremlin. Have changed Fuel pump relays. Also: Is it common for 1979 930s to have fuel pumps operating with key in ON position before activating starter? Any input sincerely appreciated.
