i have a 93 accord with the F22. my problem is the number one piston has no power. cap an button are good. wires and plugs are brand new and i put a new injector in it. has 150psi in compression test. but when you pull the plug wire off there is no drop in idle and the car runs the same.

 

What color is the center electrode of the suspect cylinder's spark plug?
Does the center electrode look shiny/glazed? Any metallic specks noted?

While you're at it; with the plug out of the head, (and you've already looked at it) lay it on top of the valve cover with the wire attached, start the engine and confirm VISUALLY that you have spark.
*You MAY want to install a spare plug in it's place while you do this.

nope spark plugs look good it has spark already took off spark plug and put it on the valve cover

 

the plug has a good spark. an i re-gapped them while they where out. still has the same problem.
another thought. the fuel return vavle is right in front of that injector, could the fuel possibly be returning to the the tank and not going to the injector?
