No OBD ignition readout - What does this mean? 850 1995

The last 3 times I have tried to pull codes off of the A-6 ignition port I get no response. Push the button and the red light comes on but no blinks. Could this mean the ignition ECU is bad or perhaps something else? Any way to diagnose what's going on? FYI - the A-1 and A-2 ports work fine with no codes.

I am about to install a new cam position sensor but I want to make sure I'm on the right track before I throw any more parts at it. I also have a new fuel pump relay ready to go.

My car still won't start and unfortunately work etc. has been too busy for me to spend lots of time diagnosing this problem...

As always, thanks for any help!
Jim

    Throw your fuel pump relay in first, quick and easier to get at than the cam sensor.

    It means you do not have the LH3.2-Jetronic ECU. The LH3.2 Jetronic engine management sysytem used a seperate ECU to control the EZ-129 K ignition thus using socket 6 of mudule A to read codes.

    I have a 1994 850 Turbo and my A6 port doesn't work either. It didn't work in my previous 1994. A1, A2, A3, A7, B1, B2, B5 and B6 are the only ones that have responded on both of my 1994 cars.
