Good Morning,
I've got a real toughy here. 2012 Focus 2.0 GDI intermittent No Crank/No Start. The starter relay will not click and the solenoid will not click. Battery ok, all TSB's and SSM's checked. Only fault code is in the BCM B10E5:15 PCM Wakeup signal open or short to battery. Any common issues anyone has ran into? The wiring diagram for this PCM Wakeup signal is very vague and the PCM connector is such a PITA to get to that by the time I've got access to the PCM connector the engine will start fine again. I wasn't even sure if this circuit was the issue or not so I depinned it from the BJB and the concern still occurs intermittently like I did nothing. I no longer have access to running a hotline request or the FMCdealer forums as I'm a Ford technical instructor now.
Any help would be appreciated!
