car cranked died error light said check air bag then cranked later

Hello, did the vehicle ever run? You state "cranked died...then cranked later". I'm not sure I understand fully. If the engine is cranking over quickly and strong, but not starting - there is an engine performance problem that must be investigated. If the engine starts but then stalls and then you have to wait 30 minutes, that's another issue altogether. Either way, hands on technical support at a shop near you is the best option: www.repairpal.com/repair-shops
