Just had a complete rebuild, went to fire it up and i had no high pressure oil. My buddy at ford gave me some blocked off stand tubes to try to find the leak. one of which has an ico sensor in it. My left side holds pressure fine, but my right side (passenger) doesnt. I replaced o rings today and tested, still no pressure building on that side. the injectors are all okay, no visible leaks and i cant hear a leak. The tops still have their retaining rings and arent blown out? anyone have any sugestions??
