started car up..quit after 10 seconds..went to restart..was cranking but wouldnt catch...now wont even crank...but the car has power...starter???..???

if it wont even crank then its likly the starter.. wehn you trun the key do you hear a click? (the sylinoid engaging?) ive seen the bearings on cranks fail like that-hope that didnt happen to ya..

Check the starter gear to make sure it's not sheered or frozen up....then go for it.

try hitting it with a hammer a few times, not kidding. if that works then u need to replace it ASAP cause that will only work a few times.
