is your crank pos sensor a reluctor or hall effect? You can verify a signal on either by using a LED, wired to test leads. A reluctor would have a weaker light, as it is depending on the strength of the magnetic field to get its signal from. The hall effect would have power ( +8v to 14v) supplied to it, so it would be easier to see.

Is the sensor face, centered over the tops of the teeth on the trigger wheel? ( not too much left or right) What is the air gap you are running between the sensor face and the trigger wheel? What is the specification on your particular sensor in reference to air gap?

Here is a write-up on using the LED to test, instead of an O-scope
