what does it mean when my car won't crank and says engine power is reduced?

That lamp is a indicator of problems with Electronic Thottle Control. That does not usally cause a no start issue. You will need to have fault codes retrived to get better anwser to your problem. I suspect it could have a theft control system that could prevent car from starting. Check battery charge condition and retry after a 30min sit and it may start. Otherwise you may need to haved it towed to a shop for diagnosis.
