[QUOTE="RJones, post: 434755, member: 20152"] Update: In another forum, had a member suggest I do this..... Try unplugging your coolant temp sensor and see if it starts. On these older vehicles when they go the computer reads -40 and it flood the engine when trying to cold start. I unplugged the coolant temp sensor and it started. Might not be the reason it died, but could be the reason it's hasn't been starting. Could also be a coincidence, but it did start. Took about 4 tries and it kept acting like it was going to start. Gave it a little gas as a boost and it started. Let it run for a bit, and idled a bit rough at first. Turned it back off and it started again. Waited a little while and it started again. I still think I might have something going on with the timing and maybe the distributor isn't set just right, but I wanted to post this update for now. [/QUOTE]
