Default Camshaft Position Sensor Issue (Car won't start)

Hi, I have a '93 Legacy 2.2L NA. The other morning I went out to start it and it wouldn't start. It had run fine the night before. The engine turns over and the spark plugs are getting spark and the fuel pump is delivering fuel. I then decided to check the car's computer and see if it was of any help. I connected the little diagnostic connectors under the dash and flashed the CEL. The trouble codes it gave me were for the #3 fuel injector and the camshaft position sensor. I don't think having one fuel injector out would prevent the car from starting, it would just make it run rough, right? After thinking about this I looked in my manual to see how to test the camshaft position sensor. It said to disconnect the harness from the sensor, hook a multimeter up to it and turn the engine over. The output from the sensor should be around 0.1 volts, varying in time with the engine turning. I did this and I got a reading of 0.2 and 0.3 volts varying back and forth as the engine turns. Occasionally the voltage would drop down to 0.1 for a moment but it stayed mostly at 0.2 and 0.3. My first thought was that the sensor must be okay because the reading was only one to two tenths of a volt off of what the specifications are. But then I got to thinking about it more and I realized that although thats only one to two tenths off normal, it is also two to three times what it should be. I guess what I'm getting at is is this a very sensitive sensor? Can a small difference in voltage cause trouble? I searched in old threads trying to find something out about this but was unsuccessful. Also, even though I'm getting spark does anybody think that there could be a problem with the coilpack/ignitor? For example, maybe it's giving spark, but not at the right time? If the car had died while running I would suspect the timing belt but since it just won't start I don't know what to think. Thanks for any help you folks can give me.
