ECU Bad? I need some help...

Hey guys... I'm new. I guess you can tell, but this one has me confused...

Heres the problem, over-fueling. To an extreme amount. Second cylinder on pass side is filling with straight fuel. I swapped injectors with the First cylinder on the same side, expecting #1 to start spewing the fuel. But it's not! Again it's #2. IF the injectors remains unplugged the cylinder will clean itself of fuel. But the moment it's plugged in it will start to pour the gas in.

It poured enough gas in the cylinder it hydrolocked when the compression gauge was attached to that cylinder only.

Any help would be greatly appreciated!

Re: ECU Bad? I need some help...

What is it in? I know the ECU's in the 96 to 97 Mustang GT's tended to Crystallize and cause problems with fuel issues. I know, I have a 96 GT it happened to and had to swap in a 98 computer. It cured my fuel issues. My car used to pop out the exhaust cause so much raw fuel was leaking down the cylinder walls. It definitely was the computer.
