Hi! I'm new here and don't know too much about cars. All I know is that I turn the key and everything comes on - except the engine. Dash lights come on, a/c, radio, etc. But, the engine won't turn over at all, and the anti-theft dash indicator remains on. Any ideas? I already tried disconnecting the negative battery cable and reconnecting, but did not work. Please help!!!

Well, just thought I would let you know that I had to get the van towed to the dealer, they told me that my Power Control Module had failed and that I would need a new one....$750 later....
Anyone heard of this happening? My car is a 2003 and it seems a little crazy!
I'd appreciate your input!
