She took the car to find out why it wouldnt pass smog. According to her car was running ok, and started normally that morning. But when she returned car wont even turn over. Additionally, the tech was rude and demanded car be removed from the shop. "A piece of junk" is what he reportedly called it.
I just need some idea of what to tell her. Where to begin to look for the problem.
If the battery and starter are good where else would we look to find origins of no crank condition. She reports that nothing happens when key is turned.

Does this car have a starter relay? Does it need activation by computer?
could the problem be the immobilization system.
I maintained my 240 and 740 for over 20 years at this site, but I no longer own them. But as you know , those cars were a bit different than the S70.
I just need a little push in the right direction. A wiring diagram would be a good start. But I just need to know where to look.

Any help would be much appreciated.
