Well here is the story, My saab shop said I was missing a ground between the ABS relay and the ECU. I tested the ground's and there is no break's. But I found a break in the in the wires coming off the pump relay. The Pin 35 (Blue) get's spliced to 2-yellow's (pump power) and a black that goes back to the ECU pin 1. The black to pin 1 passes through a diode? not sure, but it was broke at the diode to wire connection. So i spliced it back together and now the ABS pump is not running, thus no power brakes! I tested the relay and it work's. I could manualy trigger the relay and the pump will run so we have no fuse,power, or pump issues. And there is power to the relay (Pin 86), but Pin 85 is not getting grounded. Pin 85 run's to the ECU pin 50 and the connection is fine. Does this mean that my ECU is shot? and were does the other wire coming off of Pin 85 of the Pump relay go? to the pump? I want to thank anders for helping me in my last post.
