2005 Bmw 645ci cranks but wonít fire

I have a 2005 Bmw 645ci that drove 2 years ago and then sat for the time. I get the car back and did major oil gaskets. Car cranks strong but wonít fire. Cams are turning in front and back of the motor on both sides. Checked for spark and thereís no spark when grounding out the plug. Thereís pressure at the rail and air connections are tight.New spark plugs and good coils. Just changed main ecu wire harness and dme with key and cas from same part number. Synced dme and cas in inpa. Havenít programmed any modules yet. Still getting the same crank no start. Changed cam sensors and crankshaft sensor is testing good with voltmeter. Swapped ivm with 3 different good ones and same crank no start. Checked all grounds and cleaned and battery is new. Checked the whole car as she is on jack stands now with easy access to stuff. Registered to car with inpa. I have the electric fan and DMTL heater and ambient temp sensor unplugged. Someone with some sense guide me to get this back running. No games Attached are the only codes the cars throwing. I have bumper off and headlights unplugged and few other codes that are irrelevant for the time

I have no idea why your car will not start, but just wanted to let you know that this is really a 2012+ 6-series forum, and there is no forum for your car on this site. Don't ask me why. But there are forums for your car on other BMW forum sites.
