Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hi, My name is*****'m happy to help you. During our conversation, I may be presenting you with different things to try, and ask you some Questions to get a better understand of the issue so I can answer your question properly. So stick with me to the end, and I am sure we should be able to get this issue resolved for you!
Did you change the timing chains along with the tensioners you replaced?
Oh, you did the primary tensioner. The one on the big chain. Correct?
Did you remove the primary chain? It sounds like it may have jumped a tooth or two.
Let me know..
Try this. Unplug Bank 2 Cam Sensor and see if it starts and idles. If it does, turn it off and return back and let me know. If it still doesn't start, plug it back in, and then unplug Bank 1 Cam Sensor and same thing. See if it starts and idles.
Thank you. That verifies that your mechanical timing is off a tooth. It most likely jump time when you started it and the tensioner did not prime yet. Normally when we do timing chain work, we pull the fuel pump fuse and when we are done, we turn the engine over a few times for the tensioners to build oil pressure. Then we put the fuse in and were good.
So at this point, your mechanical timing is off a tooth or 2 and will require the timing chain to be removed and re-positioned to the correct timing and then re-assembled. Which remember to pull the fuel pump fuse when you do this.

It maybe easier to speak with you on how to set that up.
Let me know if you would like to speak with me, or continue this way.
3 teeth could mean there is valve damage. The only way to know is to put the engine on TDC and do a cylinder leak down on all cylinders.
What I use is a Chain Vise Grip to grab the intake sprocket and I turn the Cam with that. Then I will take the timing chain and line up all the colored links to the proper timing marks.
That video should help you get the chain on right.
Please don't forget to Rate me. That is how I get credit for my work.
