Car will not start

Driving down the road minding my own business, and the engine shuts off on me. No sputtering, no surging, no stalling, it just shuts off. The check engine light did not come on. It still turns over but will not start. Not getting any spark. There is a connector with two wires that connects to the coil pack. I have been told that this supplies the voltage to the coil pack. One wire looks red and the other is black with a white stripe. I say it looks red because it is not a bright red. It is a faded red. It could be another color because it is faded a lot. I thought the ECM may have bet its maker, but I am not sure. A friend suggested it could be the crankshaft position sensor (I have read where this vehicle has two of them.) And/or the camshaft position sensor. Also, I have looked for the crankshaft position sensor, and it looks like you have to take the harmonic balancer/pulley off to get to the bolt that holds the crankshaft position sensor in place. I would like help testing the crankshaft and camshaft position sensors before taking them out. I do have a volt ohm meter, and I know how to use it. (I have built a Heathkit TV with my dad when I was in high school and other Heathkit items.) Also, I would like advice on taking the sensors out if needed. Advice such as do I have to take the harmonic balance/pulley off to remove the crankshaft position sensor behind it, and where are the other two sensors. Also, I want to make sure that the ECM is getting voltage to it. Which wire(s) should I test when the ignition is in the on position. I have checked all the fuses and they are okay. I am a decent backyard mechanic. I have replaced head gaskets twice (Once on this car. It did start right up.), Clutches twice, water pumps, alternators, power steering pumps, radiators, brakes, A/C compressor, and other small items. Thanks for your help. I do appreciate it. Also, any other things you can think of to check would be appreciated. One last thing, if the crankshaft and/or camshaft position sensors are bad, would that stop the ECM from supply voltage to the coil pack and prevent spark from occurring. Thank you so much. Jim Cohn
