Hello to everyone! I have a huge problem which I hear is common with these VQ35DE engines. I replaced the valve covers both front and rear and now my baby will not start. I tested for fuel and compression and everything is great. Tested for spark and it doesnt seem to have spark at all on ANY of the ignition coils. Upon doing the valve covers, I only disconnected the battery and everything else I pleasantly moved to the side to give myself room. One of the wiring harnesses I moved to the side was the one above the timing cover on my 2004 maxima 6speed. I was careful not to pinch anything or yank on any wires but still no start. Is the wiring harness the culprit? And should I just pirchase an entire harness or find the short in the harness if it is the problem? Any advice would be helpful. Thanks in advance
Are you getting any codes, did you route the harness for the coils correctly? Could be just a bad connection I highly doubt you damaged the harness if you were careful.
The codes I have are for the crankshaft position sensor (the flywheel is missing teeth) which I had for about 6 months now and o2 sensor level high. But I also grabbed and tugged pretty hard on a 3 wire connector (brown in color) that runs in the same harness as the ignition coils and fuel injector connections. I will take a pic tomorrow. I dont know what it leads to, but its routed through the front engine mount.

yes! Unfortunately, it was the clutchplate / flywheel missing teeth and its warped. So there was no constant signal being sent to the computer. Getting the whole transmission revuilt as we speak!
