vq35hr wont start
im hoping somebody could help me here, ive tried everything and searched a lot.
what happened: i was taking a turn and got on it a little bit, kicked it out, pushed in the clutch, heard a niose and the motor stalled and i coasted home.
tried to start it and it wont start, turns fine and gets fuel im assuming no spark
what ive tried: checked the plugs, checked fuel pressure, swapped crank angle sensors, checked flywheel marks at tdc, the security light is not on when the key is in ignition, when starting the cluster lights do go off or dim, the check engine light is on with ignition, fuses are good, can smell fuel after cranking a lot.
i have the uprev tuner and was datalogging when this happened but nothing significant shows, no codes
i thought the noise i heard may ahve been the flywheel and the crank sensor got messed up but it looked fine and the marks line up at where the should be i believe
it wants to start, just doesnt. sometimes it will just crank, others it gets going a little maybe 200rpm and dies immediately.
im dumbfounded, ive checked everything that i can and tried everything that came up searching. i dont want to have to pull the motor and trans out or apart unless i have to
i have videos of essentially everything and can cipher anything if someone who can help needs it. i love this car but im sick of it, please help me fix it before i use it for metal

Since you have the uprev tune, did you accidently put your car into security mode and now you cant start your car? Try switching to a different map and see if you can start the car.

i doubt its bad gas, i had filled up with shell 93 the day before.
i appreciate all the ideas
i did just get done doing some pulls because i was checking my afrs on spray, i run a 75 shot, the afrs were down in the high 10s low 11s
but this happened after i wipped it a bit around a corner out of spray
here is the last part of the data log when it stalled

I didnt know you had nitrous hooked up. Check all wires for the nitrous connections. if you have a wire that is grounded out.... possibility that your car wont start. Keep looking....the answer is probably right in front of you, and you just cant see it yet.

Whats with the AFR values starting about halfway down?
very strange, wish I could offer more help at this point....have you tried testing the clutch switch? If its not working properly, you cannot start the car.
Side note*
unless you have already started an actual spin, as in its flipped ends on you, you NEVER want to come off the gas, or hit the brakes, when the tail steps out. I know it may have just been a panic reaction, but you need to steer into the direction of the slide, and feather the throttle, until it hooks up.

thank you, those are the deceleration afrs. the clutch switch is fine, it turns over plenty of times just wont actually start.
today i checked grounds and they are fine, tried a new rom and that didnt help, swapped plugs, coils, and plenum just to see. checked cam sensors, ive tried swapping the crank sensor, checked fuses.
im not sure im just thinking it may be something to do with the flywheel and the crank sensor markings but i heard it should start even without that sensor plugged in and it didnt. im waiting on a reply about getting a rom with the nats disabled to see if that helps if not idk i guess to the dealer or something
Side note: the information you are giving about sliding is wrong. i am not new to drifting and can well control my car, to tell someone to never use the breaks or come off the gas is not true. the info you are giving sounds a bit like a video game. also just to clerify it wasnt a spin out just a whip. and the clutch was depressed after i had regained traction. cant really remember at what point the noise was heard.

Information I gave you is correct, your situation read differently than what you just clarified.
You should never brake or lift off the throttle abruptly(Clutching in mid slide) when the back end is stepping out, it can cause a massive weight shift, and send you spinning.
My apologies if I misread your statement, but it seemed like you felt the backend get loose, and your reaction was to nail the clutch, which would unload the rear suspension, and possibly overload the front, resulting in a snap oversteer, or 4wheel slide.
