My 350z will turn on and idle around 200 rpm for about 6 seconds then it will turn off. If I give it any throttle while it’s on it will turn off. My flap in the throttle body isn’t even moving either .I put the car in my garage about two months ago and disconnected the battery while it was in there. Pulled it out the other day to this problem. Here’s what I tried so far.
throttle body from working z
maf sensor from working z
checked all lines and gaskets for vacuum
disconnected fuel regulator and I’m getting plenty of fuel
sprayed starting fluid in throttle body and nothing
new plugs
check coil packs all good
gas is good
relearned the throttle body and reset ecu
checked all fuses
my 02 sensors in the headers are running lean and the test pipe ones are running rich?? That’s a little confusing to me.
air filter is clean. I’m stuck at this point if someone can relate to my issue please give me your opinion thanks. Motor has 60k

 

I'm impressed with the troubleshooting. Are there any codes, or other recent changes to the car? It might help to post all the mods. The only troubleshooting I can think of are compression test, and fuel pressure test. And possibly inspecting the air filter.

 

Thank you I did a compression test also I forgot to add and all cylinders are fine between 150-160. I have K&n intake with filter that is clean, berks test pipes, Megan racing y pipe and catback. And the only code it’s throwing is letting me know about the o2 running rich and lean. I haven’t done a fuel pressure test yet

 

So now I unplugged my crankshaft sensor and the car idles perfect and revs up without any issue. But when it’s plugged it it won’t run? Please help

 

I would try and find a used sensor and harness to test. The sensors on this motor are a total pita.

 

Put in a new crankshaft sensor and I’m getting the same response. I’m going to check the current through that harness and see what the power is looking like. I’m praying it’s not my computer, I really don’t think it’s the computer though because this sensor is the only problem I’m having.

 

Hey did you ever figure out what the issue was I'm having the same problem?
