google "S40 battery cable fuse" for some posts on people with similar issues

 

Could possibly be a neutral starting switch (pnp) issue but not familiar with the newer models. I had a bad pnp switch (mounted on top of tranny) and had a similar no start/crank issue.

 

true the PNP switch (park-neutral position) switch can cause a no start as the ECU will think the car is in gear. One thing to try is the "shifter row" - engine off key in position 2 to unlock the sifter, foot on brake, shift from Park to Lo to Park 10-20 times fast. put car back in park and see if it fires up. What this does is scuffs up the contacts in the switch, which may be enough to send a correct signal. To determine if you have a bad starter cable fuse, you need to measure resistance from top side to the starter terminal.
