Default Fuel puddle in my intake manifold...gsr

My motor has just been rebuilt, replaced just about every sensor in the thing, and anything along the way; i've spent more hours on this thing than anyone would believe, atleast 5 a night for the past 2 months trying to get it working. I've been unable to get it to run right, i fuel foul plugs like crazy and it has gotten worse. I just noticed a loud whining noise tonight, which i believe sounded like a vacuum leak. I decided to remove the TB thinking it may have been that gasket and found 2 fuel puddles in my IM, and by puddles i mean about a half tablespoon a piece...lots of gas.... what the hell is going on? I fear bent valves...

up.. checked valve clearance and i could fit a .010 under a few intake valves, and under over half of the exhaust valves...not sure how much of an effect that could be having, anyone have ideas?

Fuel Injectors. That is where fuel comes from..... But really you might have an injector that is not closing and dripping into the manifold. That would also explain the fouled plugs.

^^^^ I'm with this guy.
That's the only reason I've seen gas in a manifold on a Honda

Going to be looking at it throughout this week. I'm guessing its my injectors so im going after those first.

get a test light and backprobe each one of the injectors. the test light should pulse.

Honda injectors work on constant power, with a computer suppled ground. Once the computer applies ground, the injector is closed. If the computer does not ground the injector, it will just continously pour fuel into the cylinder. This is bad, because it can wash the oil off the cylinder wall and cause damage.

If the test light does not pulse, check the wiring for that injector. If the wiring seems fine, back probe the proper pin out on the computer. If the computer doesnt send out a pulsing signal, replace the computer.
