I'm experiencing an intermittent no start problem on a 2007 NC3V 3500. The pre-start dash display is normal but when I turn the key to the start position I get a single relay click and no crank. If I try again once or twice the engine will then start normally, and continue to do so. This seems to occur only on the first start after a long shutdown, otherwise normal. I do not believe it has anything to do with the battery or cabling as the battery and 'Y' cable are only about a year old, and the bus voltage is normal pre-start (battery is normally kept on a float charger.) Cranking is easy and the engine starts instantly once it decides to work. No codes are present, at least no OBDII codes. Of course this is nearly impossible to troubleshoot since the problem is so intermittent.
It seems like just a lazy switch or relay. Can anyone provide any guidance on where to start?
