my kids 1997 sunfire has spark and good fuel pressure at the fuel rail, but the injectors are not working. Would it be the crank position sensor or the pcm?

Check the oil pressure switch, on some older gm's the switch controls the injector circuit, won't let the car start if oil pressure is low or oil level is low, good luck.

rent a noid light set from a local parts store chain and remove the injector wires and check to see if there i a pulse going to the injectors. if ur getting fuel and spark there is only one other main component that you need aside from air and thats compression
