No injector pulse or spark
 

I have a 06 BMW 325i that will not start. It cranks but does not start. I replaced the crank sensor with no luck. I did test the wiring for the injectors and COP's. I am missing the signal to the injectors and COP's. I need to know what do i need to check next. I also have another question. The cam sensor caps, when you redo the timing how are they exactly supposed to go back on the cams? I guess they could also be called the cam sensor pickups. Any help on these matters will be greatly appreciated.
