#3 injector dumping fuel

[speed-s13]

I have a 92 coupe 5 spd. KA24de with 235,000 miles and cyl. #3 is getting loaded up with fuel, alot of fuel. Ive ohmed the injector and replaced with a known good one,new injector o-rings, checked the signal wire from the ecu for a short to ground and performed the diagnostic tests on the ecu,of course i get code 55. Compressions were 155 psi across the head and no coolant in the oil or vise versa. I checked for spark and replaced the #3 plug wire with a known good one. With the injector plugged in the engine smokes(white with a raw fuel smell) a hell of alot, unplugged no more smoke. also while the cranking engine with plugs out and coil dissconnected fuel pours out the spark plug hole,with the the injector unplugged no fuel comes out, this leads me to belive either I am missing the most basic problem or my ecu is junk.And it only seems to happen when its wet out side.

anyone have any insight on my problem? encountered this before? any help is greatly appreciated

thanks,john

hey maybe u can also help me... my ka24e.. my third injector is funny too i think... whenver i would push on it it would make the engine rock back and forth and sound all funny, but when i push on all the other injectors the engine doesn't do anything... what could be up when my injector 3 only does that when i push on it?
