Ok here goes, bought a 2000 7.3...had a blown engine. Rebuilt the engine, block bored .40 over, new heads, new UVCHs and quarter fix. Swamps 175/146 single shot injectors with tunes. Started ran truck, drove truck roughly 55 miles, ran like crap, no power and horrible shake. Checked temp on exhaust manifold, 300 at each port on passenger side, 170-200 on drivers side. No codes present and no check engine light. Ohm checked from IDM to injectors, all in spec. Does not smoke at idle. With engine running, unplugged the Drivers side harness truck still runs, idle drops slightly...plug back in and unplug passenger side, engine dies immediately. Cleared codes, restarted ran and no codes present. Any ideas would be great!
