Ok....I know CSIPSD will likely move this to the 7.3 thread......but trucks don't have a GPCM...I am getting an intermittent #5 glow plug code with SES light.....I pulled the connectors at the valve cover and did dielectric grease on them.....what else to check?....Light is off now.....but this is 3weeks after the connector deal....switch GPCM connectors ??.....under valve cover harnesses? or glow plugs ?
