    Your theory seems pretty accurate. However, what made you think the plugs were bad?

    I pulled one to check it. Figured it was best to keep it simple; fuel, spark, air. Pulling the plug was the easiest thing to check... Figuring out why they had failed might be a better mystery to solve.

    Is it possible for a fuel pump relay to prime the pumps but not run after the fact?

    I had the same issue I had before this morning, car almost started (running off the cold start valve I assume) but would not idle. I don't know what made me try it but I swapped out the fuel pump relay for a new one and my car immediately started.

    fuel pump relays can do all sorts of wierd shit. I once saw a relay that shorted the ignition system and caused a no spark situation

    Replaced the O2 sensor yesterday. That, along with the new fuel pump relay seems to have made for a pretty happy car. She runs great but her head ticks like mad so that's next on the list.
