1998 200sx 1.6 won't start
 

My daughter was driving and her call cut out and wouldn't start. Timing chain,fuel pump,distributor all check out. I did a complete tuneup and checked voltages to the sensors. Crank sensor isn't getting any voltage. I checked codes, P0105 MAP/BARO circuit malfunction and P0505 Idle control system malfunction. Does anybody think the computer is bad? Any other leads?
