engine wont start!

[BigTerry]

08 ram 5.7 with 166000 miles .engine will spin and hit once and then keep spinning till I turn off the key..
could a weak battery cause this or bad crank sensor?

Look at my no start thread, it could be a bad coolant temperature sensor, when bad it tells the pcm that temperature is 40 below and floods the **** out of the engine to warm up faster.
