Ok, based upon your description of events, symptoms including the fault code, this does indeed sound like the timing belt has either broken or jumped teeth. The timing belt on yours is due to be replaced every 60K to 90K miles, so you are definitely in the range when it could break. It is also 7yrs old, which it the max time limit on replacing it as it does dry out and crack and can either break or stretch and jump timing

I can understand that.....let me throw some more information at you:
I dont hear the fuel pump, even if in the tank, on a car this small, I would think I would hear it, I should test fuel pressure, but havent done so.......
I have tested for voltage at cam sensor connection:
Ignition on, not cranked over: blk/white: 14.5 volts
ignition on AND cranking over engine: blk/blue: 0.0 volts
I have come to understand (maybe in error) that if the crank sensor was bad then the ecu would not supply proper signal to cam sensor and fuel pump. Please correct me if I am wrong?
I read ALOT online of timing issues on the 1.6 Accent, but I would expect with a rubber belt there would be some symptoms prior or early warning such as bad idling or rough start. This was not the case.
I normally would expect to follow the circuit back to the ECU if there is no signal to cam sensor to check there for voltage but seems like nothing is "normal" on this car (remember car has a new cam sensor and still no start) .....Thoughts? Next steps? Please provide detials, thank you
