I recently purchased a 2003 350z and everything was great for a while, untill it didnt start. I have a new motor with little miles on it, the alternator is good, and a brand new battery. I had the starter tested at Advance Auto Parts and they said it was fine. Any ideas on what could be causing my car not to start?

 

when i turn the key it makes no noise and its 6 speed manual

 

Check any fuses? ANy lights show up on the dash?

 

yea the lights for the dash and radio and headlights come on i know nothing about a z either i came from a honda

 

i have not checked any fuses can that be the reason it doesnt even try to turn over

 

like what vic said, check for blown fuses. it must be an electrical issue since the motor doesn't crank and your battery and alternator are good.

 

Are you pushing in the clutch, have you tested the clutch switch, have you tested the starter, battery etc etc . Break out and multimeter and have some fun.

 

If you turn the key and there are no sounds whatsoever then:

1. Its the battery
2. Its the starter
3. Blown fuse

I would try getting a jump because a cold weather could kill the battery if its been sitting outside.
