when you say it wont start will the engine turn over?
if it wont turn over i think you should check your battery connections
if the engine turns over then you need to check your fuel pressure and spark and let me lknow

not all scanners a created equal. You need to check for trouble codes...............but it must be fixec by now.

It could be a bad blower motor - tap on the blower motor with the end of a hammer when you have the switch in the on position - if it comes on then it is a bad blower motor. If it doesn't come on I would check to make sure you are getting power and ground to the HVAC control head.
