Why won't my sebring gtc start???
 

I own a 2004 Chrysler Sebring GTC. 6 cylinder 2.7 liter R rated engine. My Chrysler Sebring will still not start.
I have replace the ECM PCM and the battery. My car still will not start after extensive work being done to the engine. But the only code I keep getting is p1864. It will not give any other codes but my car still will not start. It will crank but it will not turn over. No signal post for the injectors, no signal pulse for the coils, no signal post for the crank or camshaft sensors. But good continuity on all wires & grounds. All grounds are good. All the fuses & modules have been checked and are good. The ASD relay is good.
What could possibly be the problem? If my car is not turning over, why am I not getting any more codes? Why is my car not turning over?
