S80 T2 2001 will not start

[trol-53]

I recently had to rebuild my engine because the #6 piston wrist pin retainer left it's assigned area and scared the cylinder wall on the way out. After hours of labor I had the engine back under the hood when the moment of truth came. I turned the key and nothing happened.
Silence! There is power to the main fuse terminal -B- under the hood.
I am not getting a signal to the stater relay or the ECM relay also the OBD hook-up is without signals but also has power!
The battery was unplugged for over 3 months while the machine shop
was doing the work, I also broke my arm, thus the delay. So does the car have a time-out switch out some secret code? I'm at my wits end!
Am I going to have to have the car towed to Volvo and be at their mercy?
Help me OB1 KYNOBY your my only hope!
