Will it run in park? What about neutral? Is it fuel injected? Have you changed the fuel filter?

my 2001 ford windstar wont shift out of first gear.
my hood on my 1990 chev 1500 will not lock? I just replaced the grill and hood as a blazer jumped out of gear and backed into my front end!

You can also start a car in Neutral. Also remember to put your foot on the brake too.
