Help! Car Won't Start
 

Just went out to start the maxima 10 mins. after driving it and it would not start up I turn the key and I get power but I turn to 'start' and absolutely nothing happens. I don't know what to do. Here are my trouble codes:
0403(Throttle Position Sensor), 0304(Knock Sensor), 0305(EGRTS), 0401(IATS)

Dead battery? :gotme:

alternator?

its the ignition switch.. if u turn the key and absolutely nothing happens... jiggle it when you are trying to start it...
then check ur batter

I would think its alternator

Like f550 said, it is either the ignition switch (part inside the column cover) or possibly the throw-out solenoid on the starter motor.

It could be various different things. If you are getting nothing when you start up it could be:

-Dead battery
-Ignition switch
-starter

-Check the battery, try a jump
- try tapping the starter while cranking
- check the ignition switch.

A situation like this has happened to a friend, I tapped the starter while he was cranking fired up. The Gear is the starter could be stuck and thus not moving at all.

If auto try putting it in Neutral and starting.
