Plus looking at the instrument cluster for warning light's , SECURITY system - anti-theft etc....Because these will keep the vehicle from starting . Hook up a professional type scanner to see if all the control modules on the vehicle will communicate with the tool . A shorted data bus wire , module etc... will also keep the vehicle from starting . Plus you don't discribe the problem correctly .Turning the key to start an nothing happening is a no-crank - no start condition , turning the key to start an the starter engages an spins the engine over - is a crank - no start .
