All six ignition coils no spark

Hi,

When you say there is an open circuit to the crank, what do you mean? An open means no continuity in a wire, Please explain. Also, the ground to all coils is common. Are you certain it is tight, clean, and in good condition? See pic 1

I have one other question. Is the new engine from the same year, make, and model vehicle?

Hello,
To your first question, I said open current, I mean an ignition current output when you switch the ignition On, your second question, yes the ground are tight and clean, I added more ground from chassis to engine,
Your last question, the engine aren't of the same year model but their closely similar with little differences and the difference is the old is carrying 2 camshaft sensor while newer engine is infinity Qx4 and its having additional sensor of two wire at the front of the engine on the timing cover by the right if you are facing the car,I also learned that the throttle body is not clipping as it use to normally but the ETCC fuse is normal. please I need a guide on how to get a spark on the coils. .
Joe.

Hi,

I didn't realize the engine was different. Honestly, that's a tough one because now I don't know if I should focus on the pathfinder or the Qx4. As far as contacting you, it's the site's policy that we don't. I hope you understand.

I attached the entire wiring schematic for the power-train management for the Nissan. I overlapped them so you could follow them. Let me know if that helps.

As far as the sensors being different, see if the part from the old engine can be switched. Hopefully the design isn't much different.
