Got my Trailblazer in a trade not running. Went through it and replaced CDI,starter, ignition, etc... got it running finally. Then one day it just died on me. Wouldn't start back up. Hot busy at work&it was pushed to back burner for a bit. Bit the bullet (so to speak) and ordered top end. Finally got around to doing it. Long story short, it brought it back to life yet again FINALLY.
