robp823 Posted April 20, 2009 Share Posted April 20, 2009 Got an 01 f-250 runs rough all the time.Got p1316 continous and p1277.P1316 led me to ppt fj9.Which tells you to run self test and see if any other codes are stored. If yes tells you to go to appropiate ppt test for that dtc.So i went to ppt for p1277 which is NA11.Followed NA11 measuring high and low side resistances for that injector circuit which is 7 from the glow plug connector to the idm connector.Resistance was in spec. Could this be a possible Valve cover gasket issue? Quote Link to comment Share on other sites More sharing options...

dieseldoc Posted April 25, 2009 Share Posted April 25, 2009 The under valve cover harnesses are notorious for getting burned because the glow pug pins and wires are a little small for the amperage load they have to carry. Generally the lock breaks and the connector has a loose connection, on the newer ones. Usually it will cause and intermittent miss. However if the connecto has been loose for a while, it is possible the pins are burnt so bad they wont make a connection anymore. It is a cause worth checking out. Sorry it took so long for a response, my computer crashed making it difficult to log in. I am surprised nobody else has responded to your questions Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted April 25, 2009 Share Posted April 25, 2009 Yeah, how did we miss this? I read it but never got back to it. Anyhoo, dieseldoc's reply is pretty much the common scenario. You can also READ THIS. Quote Link to comment Share on other sites More sharing options...
