No start issue after charging problem.

Here's the background: 2003 Chevy Astro 2WD. Driving the van to Tucson about a month ago the battery light came on and the voltmeter dropped to 12v. Turned around and got the van home though it completely drained the battery in the process. With a charged battery the van would start but would run rough with a flashing SES light and the voltmeter remained on 12v. It started a few times that way and now will turn over but refuses to start. I can hear the fuel pump prime and can smell fuel, so I do not believe its a fuel problem.
I work out of the country most of the time and have spent the last month in Canada. I've just had a chance to get to the van this week.
I know that a flashing SES light indicates a gross misfire and 12v when running indicates a charging problem. My code reader would not read any codes. For some reason when I plugged the code reader in it would cause all the warning lights on the dash to illuminate at once.
- Took the alternator to be tested and it tested bad. Replaced alternator with a brand new (not reman) alternator. Still nogo.
At this point the code reader started reading codes OK. Showed P0351 "Primary Ignition Coil" code.
- Replaced ignition coil with new coil. Still nogo.
- Had ignition control module tested and tested bad. replaced with new module. Still nogo.
- Replaced Cap/Rotor and plugs/wires. Still nogo.
- replaced crank position sensor - nogo.
Still showing P0351 code. Still will turn over but will not start. Unfortunately I have to return to Canada tomorrow so I'm out of time. I was really hoping to have this fixed for Anya before I left, but its looking grim. About the only things left that I can think of would be the ECM but I'm hoping for other suggestions before I go that route.
