When starting she wants to turn over but won't. on 1998 Buick LeSabre

Wondering if this could be the key and sensor problem. Have tried several other things and problem persists. Noticed that the ignition lock cylinder wires can break, but would it still crank and almost turn over?

Yes it would or start for a couple of seconds. Is your security light staying on or flashing. If so it is the passlock system. Check YouTube videos, search passlock for some good information. Logging off, be back tomorrow.
