Hello everybody, my Saab makes Mucken and the factory saddle doesn’t get any further. Every few days the car doesn’t jump on. Battery is full, starter goes off normally. After 10-12 hours or sometimes even a few days it starts as if nothing had happened. Every time in the workshop the Saab loads normally. According to the workshop, the alarm system only goes on the starter and not the pump. They already checked that. Today it doesn’t run again. The fuse is ok. But the test lamp shows that ss there is no voltage on the fuse terminal when starting. I have now just placed the 12 volts on the fuse terminal of the pump from another fuse. And look, I could hear the pump and the car has then started without any problems! My question is now from where does the cable come from to the fuse? Because there must be the error!? Must be the fuse with running motor duration plus or only if there is not enough pressure in the system? Is there a Schematic for pump control? Thank you from the now slightly unnerved Saab driver.
