the left bank, cyl 1,3,5,7, receive just enough fuel to slightly warm the exhaust manifold. No fuel getting to them. Noid check shows current impulse, fuel pressure OK. Cylinders 2,4,6,8, fire and run the engine. What has happened that one complete bank has quit receiving fuel? Is there a central orifice in the injector system that feeds each bank? It appears that there is a blockage in the fuel route and a central point for each bank being blocked would affect one bank and not the other.
