Found this. Posting it so I will know where it is later.
If you disconnect the battery the fault codes are erased so you need to hook it back up and try to start it again. If it won't start then check for new fault codes without disconnecting the battery. Fuse N in the power distribution center (30A) is what supplies power to the ASD actuation coil and switch points (red/white wire) on pins A and B ( pins toward the front of the car and the outside of the box, respectively). If when you crank the engine there are signals from the cam and crank sensor indicating that the engine is turning then the powertrain controller gets those signal and grounds pin C (toward the rear of the car) and that actuates the coil and allows the points to close which sends power out pin D to the plugs, fuel pump, oxygen sensor, etc. If you aren't getting that power, then probably the points aren't closing because probably either the cam or crank sensor isn't working. But note I said probably, you can't be sure why until you either check the sensor signal wires or get a fault code for one or the other sensor being bad. You can check the ASD function because the powertrain controller will close the points for 1 second when you turn the ignition switch to 'run'. So see if you see that at the ignition coil 12 volt wire (dark green/orange) for 1 second. If you do, then you know the ASD and its circuit are OK. And the question is what doesn't the PCM like about the situation (which sensor signal is missing)? You can remove the relay and jump from pin B to D (sideways across the box, not lengthwise) which will power the fuel pump and spark coil, and you can try and start it (but it still may not start without the signals). Just don't drive around with it that way because it is dangerous in the event of an accident to have the fuel pump still running.
So let me know what you learn.

A bad cam sensor shut my '99 Chevy down.
