Well this is what puzzles me and the electrician. However, we've just tried to start it and it doesn't fire up! BUT, when you stop trying you can hear it buzzing as though it's retracting any fuel and dropping it in the tank. He thinks the plugs been wired wrong, so tomorrow we're going to go black>blue then red > black. He thinks the plugs wired opposite from factory hence why it won't start.. Yet still.. It whines after you stop cranking which would indicate it's getting power. Seriously fucked off with this tuning developments pump. (Which is actually a walbro anyway)
