tried new ECU... checked what you're talking about 1civic. All B20's are OBD2..

Purged the fuel line. I'm getting fuel to the rail. you can hear it running through. Again. I checked the line. It's making it all the way to the fuel rail. Gone through 2 different main relays. 2 different ecus. All ground are connected.

Tomorrow, I'm gonna change the fuel pump again. Change the injectors, the main relay again, and maybe even go as far as changing the fuel rail.
