Will the vehicle start and run? If it cranks good but won't start, have a helper crank it, while you visuall check for spark at the plugs. If you have spark everywhere, use a gage and check fuel pressure. Can you check applicable trouble codes? I hate to see you throw parts at it. Usually the computer has to see both the cam and crank sensor signal or it won't ground the asd relay. The asd relay supplies voltage to several circuits.
