OK got the engine in and everything buttoned up, turns over but wont fire. I have a fass 150 so I know the filter head in the engine bay has fuel, the plunger is hard. I cracked the bleeder screw to make sure there is no air. I tried putting compressed air to the fuel return line, I guess it needs 80psi to help the injectors work. I have a small fuel leak in the valley, not sure if its coming from the CP3 or a fuel line. I noticed fuel dripping down the back of the engine. I'll look at that today. I also reloaded the tune as well. Any suggestions?
