Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.Can you tell me which fault codes are returning, is it just the P115D or are you dealing with all the codes you have listed? Post back when you can with the details and I will try and help you determine the cause.
I would suspect if you can get it running with the Cam sensor unplugged then that may very well be the case. I think your next step would be to check cam timing. Not much else makes sense with everything you have already done.
