Chi-town
I just went back and reread this entire thread.
What I would do is stick to the simplest things first method.
So the first thing I would want to know without a doubt is what the overall problem is.
Is it a fuel delivery problem? or a spark delivery problem?. Or both.?
I would test the fuel and ignition systems using starting fluid and a spark tester.
Easy to do, reliable and inexpensive.
If I chase the fuel system when I have an ignition issue I am chasing my tail.
If I chase the ignition system when I have a fuel issue I am chasing my tail.
If I have an issue that affects both systems I don't know what I am chasing
So if I was going to DIY this issue.
I would want to know With out a doubt,is it a fuel issue? an ignition issue ?or both???? (I am beginning to think you have both)
Once I know the answer then I have a solid foundation to my diagnosis and proper direction to procced.
Hope this helps
