Bmw 2006 530xi Please Help!!!

[edwards095]

I have a BMW 2006 530xi (n52 engine). The car cranks heavy like it wants to start but does not start. I am getting fuel, spark & air. I changed the throttle body, cams and crankshaft sensors. Any sort of advice would be greatly appreciated!!! Basically, the serpentine belt got stuck into the engine and i took out all the pieces and reset the timing perfectly with the correct tool. Now i'm stuck with it still cranking.. Did a fuel pressure, compression, and spark test. They were all good, however, the spark was sort of on the low side.. But the car should start. (Bought the car not running.)
