1996 Windstar won't start after airbag deployed

My 1996 Ford Windstar was recentlly in a front end collision involving airbag deployment. I am away from home and I am told that although the vehicle will turn over, it will not start. Is there a sensor connected to the airbag system that will prevent starting or is this more likely caused by other damage?

Also - is there a certification process for the replacement of airbags or is this a doable home mechanic repair?

I am told damage is minor other than bumper damage and airbag deployment.

Thanks in advance for the help!
