Glad to hear it is finally resolved. But in agreement with Jeff, really like to find out source of failure. 1 item that may give an answer. Did you flush the fuel line prior to connecting it to the rail ? Fuel comes in on that side of the engine and could possibly be source of contamination of the injectors. I had jumped the relay and flushed the line from tank to engine prior to initial startup. Is Ford standing behind the injectors ?
