I have a 1997 Malibu and there is no spark at the spark plugs. I have replaced one of the crankshaft sensors, the coils, ignition module the plugs and the wires and the other crankshaft sensor is showing .6 volts when the car is cranked. I am out of ideas any suggestions?

Hmm, are you sure that you dont have the passlock problem? Is the theft light blinking in the dash as the engine just cranks and cranks? The passlock problem might look like a no spark situation.
