My 2006 g35 (A/T) turns over but doesn’t start and I just recently replaced the battery and got the alternator and starter tested at autozone. The fuel pump is a brand new walbro 255 and idk what is causing it to not fire up! Any ideas on what’s going on?? Thanks in advance

 

Is the NATS indicator light to the left side of the dash SOLID RED when cranking?

Does it sound like it's trying to catch or is it just turning the engine?

Does your tach move when cranking?

 

No the light isn’t on. And the rpms does move and it sounds like it wants to start but just doesn’t

 

Pull and inspect the spark plugs. What's the history on the vehicle, did it used to run? When was the last time it did run and were there any other details you can give about why it stopped running?

 

Check engine light on? U can read the code if it is.
