Up until I actually saw the grayish-blue smoke ride from either side of my motor, I had come to the following conclusions draw from the way she was driving/running.

Failing leading ignitor, intermittantly shorting fuel injector wiring harness, and bad coils.

The problem worsens each drive, even with new coils and a new GM igniter for leading.

Now i know the problem isn't electrical as smoke comes from the engine bay on attempted (always failed) startup.

Intake mani. gasket? Leaky injectors? Im fresh out of ideas, anybody have any suggestions?

 

so you may have an exhaust leak.

 

Verify that you have spark where you need it...
