Last cylinder flooded with gas on rear drivers side, compression good, new cylinder heads installed, plugs, wires, while running strong smell of gas from exhaust pipe I tested with anold light on injector wire flashes. So listen for ticking while running no ticking all other injectors working fine just the one. I hooked up a outside injecter started engine seems like injector is sticking open and gets hot fast. No ticking sound ececpt when first turn on engine just one click and then gets hot like full power to injector

You have an injector driver inside the computer that is stuck, you need to replace the ECM
