So does the engine still crank though? And how about some details, did you just buy/get the car, had it been sitting for a while or did this problem just occur randomly?

Code 12 - No "NE" or "G" signal to ECU within 2 seconds after engine has been cranked. - Trouble Area: Distributor circuit, Distributor, Stater Signal circuit, ECU.

Sounds like the cam sensor is busted or the circuit is cut. It is in the distributor. The only cam/crank sensor is in the distributor, so a busted sensor means not start.
