Starting a fresh rebuild

[vex]

well, worked a little on it today. Checked a lot of things out.

First up vac leaks:
I've checked everything, new gaskets, new intake caps, etc. No way is it leaking in enough to keep it from starting.

Fuel:
I've done everything to check to ensure that I'm getting fuel in the engine except pulling the primary and putting voltage to it to see the spray pattern. Checked resistance, checked major components along the path, checked main relay. They all check in spec. While cranking I heard the high pitched tap of the injector firing as well. By all means, I should be getting fuel dumped into the engine.

Spark:
When I pulled the leading plugs I noticed they were wet, not a super flood, but enough to ensure that the spark plugs are getting fuel to ignite--at least I think they are. I didn't really focus on the spark to ensure that I have good blue spark or not, I'll check that next time I head out.

ECU:
I hooked up a stock ECU and still had the same trouble. No desire to start up.

When I came into the garage today, it actually started right up without issue, and attempted to stay started for a few seconds before puttering out.

I'm still scratching my head on this one. I may attempt to turn down the fuel pressure to around 10psi and crank it. If it still doesn't attempt to crank over, i'm not too sure what's wrong.

The plugs themselves don't look fouled, infact they look almost brand new. Can't really figure it out. It's behaving like there's no fuel in the engine, but the plugs get wet.

I've dropped in two cap fulls of 20w50 oil into the combustion chamber, but still doesn't want to turn over. Should I move to a lighter fluid (10w, 5w, etc)?

any other suggestions or comments for me to check?
