15) No vehicle speed sensor signal detected during road load conditions.
That in itself will not stop the engine from running.
By "Won't crank over" Do you mean the engine will not turn over as in the starter will not turn the engine? If so then it's probably your battery or battery cable.
If it "won't start" but does "crank" then it could be quite a few things from coil/wires/plugs, fuel pressure, bad relay, or most likely the Crankshaft Position Sensor.
To go any further, what engine (I6, V8) do you have?
On the I6 there is a connector just by the oil dipstick that goes around back of the engine. That's the CPS sensor connector. Disconnect it, reconnect it, and try again.
