Use a fuel pressure gauge to monitor the fuel pressure while you are trying to start it. If the pressure doesn't stay over 55PSI at all times, you likely have a fuel pump issue. This engine is very pressure sensitive.

If you want to talk about a different subject, start a new question in the proper category.

Where did you find your spell check program? Plowing thru that last post it doesn't start in the rain but does after a few tries or what?
Stuff like that you check for what dropped out WHILE it does that. Moisture is more likely to mess with electrical things, connections and more likely the high voltage items but not limited to them.
BTW a catalytic converter is spelled that way!
