what could be wrong with my car if I am turning the key and the engine would turn all the way over?

Check battery cables and try again, If no response may need a new battery hope this helps.

dont understand the question the engine is suppose to turn over when you turn the key

You're probably in some deep water, call the coast guard before it's too late!! Perhaps if you wrote the question correctly, you'd get a better response than you are getting.

Nobody understands what you are asking. Pardon me, if the first response was a little tongue in cheek ,as they say, it was merely written to jog you into composing a sensible question that CAN be answered.

nothing...turn the key and it should turn all the way over

dude what the f$ck are you thinking, don't turn the key!!!

Maybe your motor mounts are broken? I'm not sure, but if they aren't, then you've got a heck of a powerful starter motor!! Good luck!! (Thanks for the two points!)

Huh?

flat battery........faulty starter......knackered engine(seized)
