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 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 plugs and wires. Still 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 my wife before I left, but its looking grim. About the only things left that I can think of would be the crank senor or ECM. ------------------

What part of "SHALL NOT BE INFRINGED" is so hard to understand?!

Do you have spark at the plugs?

I believe so. I'm still in Canada and will be for at least another week but I will check as soon as I get home and let you know.

The van is fixed!!!! Woohoo!!
SO what turned out to be the problem? I don't know how but the distributor was effed up! Somehow a few teeth got stripped off the shaft and the trigger wheel for the cam sensor was broken as well!

That would do it. Glad you figured it out.

Me too! Thanks for the suggestion on checking for spark. I checked, and I wasn't, so I decided to check the cam sensor (since that was the last of the spark-controlling sensors), and it was bumping the engine to get the trigger wheel in a position that I could remove the cam sensor that allowed me to notice that the distributor wasn't spinning.[This message has been edited by OKflyboy (edited 09-09-2013).]
