G35 Engine Dies on Startup! Please Help!!!
I will probably buy a OBDII scanner today, but I cleaned the throttle body as well as MAF sensor and it started and I got it to rev to 3k RPMs but it was short lived and then died again. Just the same rountine of crank, then start, then immediately die.

Sounds to me like you've got 1 or 2 camshaft position sensors and/or a crankshaft position sensor that's failing on you. Your symptoms are exactly what those sensors will create when they go bad. They will normally trigger a code but not always.
Alright my trouble codes are as follows,
P1168
P0102
P0113
P0223
P0123
P1051
None of them having to do with the camshaft and/or crankshaft sensors, but I do believe that is the problem like you have said, but most of these are with the IAT sensor, MAF sensor, as well as throttle position switch.

Either that or when I took them out to clean them I did something wrong
lol. I will go back and make sure all my connections are good, as well as clean the MAF one more time and let it sit overnight vs 30 minutes. Hopefully this as well as new camshaft sensors and crankshaft sensor will solve the problem. Thank you for all the help and when all of this is finished Ill report back if it works or not!

wow, I hope you are able to figure out the issue and fix it.
The $1 million dollar question is , why didn't you take it back to Walmart and have them figure out what they ****ed up?
I wouldn't let them fix it, but at least make sure they know they screwed up your car etc.

Camshaft and Crankshaft sensors did the trick! Fired right up no problem after that although it seems to have a high idle..does 1400 RPMs sound normal sitting in park? Then putting it in drive goes to 1k. Just a bit paranoid. Still getting codes from MAF, IAT, and Throttle Position Sensor. Would unhooking the battery, unplugging and then plugging the sensors in, then hooking the battery back up be a good way to get these codes to clear? Ive pretty much triple checked the sensor connections and everything back the way it should. Thank you so much for all the help I'm glad she works again.

Idle should be between 650 and 700 RPMs so it's too high, you need to do an idle air relearn (search the forum). Definitely unplug the battery overnight and wait to do the IAL until after you do.
If you still have codes after that there's still an issue somewhere in the system.
