2003 350 z 6 speed wont start after accident I changed the airbag crash sensor and still no start

Does it have gas?

Welcome, but that's a helluva way to start a first post! First, a few more details on how the crash occurred and what damage was inflicted might help. Second, did you scan the diagnostic system for any codes? Third, a few more details would help: does the car crank, but not start? Does it not turn over at all?
