i bought a 07 pacifica with a 4.0 eng. that has been hit in the front . the damage is not real bad. hood, grill, radiator, ac cond., fan. my problem is. the engine won't turn over. i put a bar on the end of the crank and can't get it to move. is there something that locks everything down when there is damage that has to be reset? the car had to be running when it was hit so i'm having a hard time believing the eng. is locked up. any suggestions. thanks rod
