Car will not crank and the timing chain is fine

Well, that's good, but even if the chain was broke, the starter would still be tryiing to start the car. Since your starter wont crank the engine over, your start circuit has a malfunction. Possibly the starter went out, so you need to have that tested for a malfunction. A simple test of part of the circuit is to turn the key to on.. Now your dash warnimg lights (oil, alternator, and check engine light) should be on. Are they on, and your gauges working? If not you have lost power to the ignition switch, so check your battery connections. If the key switch turns the dash on, then turn key to start. Do you hear a click from the engine area? If not, have the starter checked. If you do hear a click, or several clicks, then power from the switch is causing that click, probably at the starter. Turn the headlights on and observe them. Are they bright? If not, charge the battery up. If they are bright, watch them while a helper turns the key to start. If the lights go dim in start, probably a bad starter. If the lights don't dim, it could be a bad connection somewhere, like the battery or starter. Good luck
