I was referencing the "cranks but no start" section ofhttp://www.moparaction.com/Tech/archive/roadside.html when they said you should be getting at least 8 volts to the + side of the coil and i am getting a steady 6, is this too little or should it still work?

It isn't that complicated. You're making it way harder than it needs to be. You tested the coil and it didn't work. Replace it and go from there.

........okay its really getting hard to keep my calm now. I just tried it with a new coil and still no spark.. I am getting 12volts to every point i am supposed to and all wires/pieces are showing good continuity but still i have zero spark.

Are you getting voltage during cranking or just when the key is on?

Allen Here's a novel idea, let's not throw a bunch of parts at the car hoping it will fix the problem and instead spend a little time diagnosing it first. Life was a little easier when I was just a wrench.

I get voltage both times which is why i kept thinking it was the ecu or coil and not some wires, but now i am just stumped on what else it could be.

12V to coil primary terminal(for several seconds only).jumper from coil primary negative terminal to ground(make/break like morse code) with the orig wire from this terminal to the ECU disconnected. Coil secondary wire plugged solidly into coil center & other end held 1/4" from ground. Not being patronizing but keeping it simple in this time of need.

Sorry if you were here it, I'd isolate the system, jumper the nec. wires and go from there to get it started, then back track whatever is nec.

What is simple for me is not nec. so for you.

So basically try what Robert said again? And that is the method that you cant leave the car running for too long or else it can damage the ignition right?

Doing what Robert says will diagnose what is the problem if it is in the ignition system. You do want to make sure if the ignition system is working.

I'm just wondering if you are disconnecting any wires when you are 'bench testing' the system.

I am gonna jump in here a lil late but need to ask, I am having overheated wiring probs as well and when I disconnect the main bat feed from the alt the sparks and melting stop.
Does this mean my alt is the short?
I hope so because they are a lot easier to swap out.

You need to start a separate thread with your question

You need a helper. I can see not wanting to leave it on when you are by yourself.

I would say you could just leave the battery dummy hooked and run out there yourself in a pinch. Do the key through the window and be quick about it.

I had a bad VR that made a sound like a clicking one time. It would work and then click off and then click on again, even with a good ground.
