Help, Car wont start and wont throw any codes!1

[oldschoolmech]

Ok to start, its a 2005 infiniti g35x. Its also my girlfriends car. Well a month ago it started idiling funky and lost some power. The lady said she hasnt had a tune up on the car in awhile. I've changed the spark plugs and it fixed thhat problem. A week or so later car started doing same thing, but now a new problem also came with it. the car would start fine but if you drove it anywhere it wouldn't start unless you waited a hour or so. I put the odb reader on it and got the bank 1 and bank 2 code, So i replaced the cam sensors and the crank sensor. Now the car wont start unless it sits for an entire day. when it does start it goes into limp mode. i double checked all plug and everything is connected. the car just wont start and isnt showing any codes. Also no problem lights illuminate on the dash, all problem lights went off when sensors were changed. some ppl say it could be the maf sensor or the tbp sensor. Any help would be awsome. I know it isnt the security system thing that these cars have. PLEASE PLEASE HELP!
Thank you

MAF or TPS... but normally you would see codes for those if they were the culprit. Unplug each one separately and try to start the car.

Ive tried all that bro. Im thinking maybe a fuel pump or something to do with it? I dont know much about newer cars and all the computer s***. Woulnt most stiff throw a code or a light on the dash though?

Did you reset ecu after camshaft sensor install?

Is that the test where u pump the gas and does the wait then hold it down then off again thing? I believe ive done the throttle reset. How do you reset the ecu?
