Swapped out the Flagship One PCM for the stock PCM and no change, still no Cam/Crank Synch, no FICM Synch, no start... Double checked the Cam sensor pigtail repair and made sure the wiring orientation from the connector was correct and it was... I have good IPR, oil level is correct, I have fuel, and 60 PSI of fuel pressure when cranking, it just won't fire... I cleared the Enhanced Powertrain and Generic Powertrain DTC's, cranked the engine over 5 - 6 times, re-ran the DTC's and none of them pop back up... My FICM appears to have the correct Voltages when cranking so I am not leaning towards a failed FICM nor PCM at this point... I get RPM on the Scangauge II when cranking so I'm pretty confident the Crank Sensor is fine... When I turn the key to start, I get the 30 second WTS light on the dash, so I'm fairly confident the GPCM is working, although I did have a code for a that.. I'm wondering if I got a bad Cam Sensor (new Motorcraft) as it tested at only 794 Ohms and the acceptable range is 800 - 1000 Ohms tested between the 2 pins... If my #1 Cylinder Injector is indeed shorted out, should I not be able to get the engine to fire if I simply disconnect the #1 Injector harness from the Injector and try to start it....? If a shorted #1 Injector coil is causing a no cam/crank synch, and I disconnect it, the PCM and FICM won't be able to know the Injector is at fault and I should then get cam/crank synch and it should fire in theory... I would expect to then see a DTC code for the #1 Injector, and that would go along way toward verifying that is the problem vs. tearing down the top of the engine again just to check it out...
Also, since no on has responded to any updates I've written here in the last week or so, I'm pretty sure I'm having a conversation with myself at this point...
