So this morning the weather is really cold and I started my car normally nothing wrong, drove for about an 1hr turned off my car n now it won't start even with brand new battery, and if I leave the car alone for awhile I can start the car up for like 2 seconds and it'll shut off again, it's keep going on n off like that... or maybe fuel injector?

 

I would suspect TB issue. There is no idle air circuit on the Z33 it's all regulated by the throttle body so if it starts but fails to idle I would start at the throttle body. Might want to try the TB relearn.

 

try cam shaft sensors... they are cheap and easy. a friend with an 03 had this issue

 

Thanks for the answers guys! And forgot to mention that I turned off the car but left my headlights on so when I went back out to my car I noticed all the interior lights started to fade and then I was like f**k! But now even with new battery still won't work.

 

Thanks for your input!

 

Thanks! Will give this a try too!

 

If you wiped out the battery start with the TB relearn.

 

I've been doing research on how to do the TB relearn but I can't seem to find it here, is it pretty hard? How can I find the procedures to do it? Thanks again for your update?

So I checked fuel, sparks, fuses etc... everything good. Cleaned out the throttle body and now car will start and idle, but if I press on gas rpm won't change and if I put in gear the car will shut off. Any inputs?

 

you change anything recently?

 

Nope

 

does it crank but just not start?

 

It'll start but even if I give it gas rpm stay the same and if I put in gear the car will shut off

 

man that is a weird one

 

Mayb a bad throttle body or bad pedal sensor?

 

Is your car automatic or manual?

 

Manual

 

What happens if you start it in gear? Does it crank but not fire?

How does it die? Immediate shut off, or does it sound like it's bogging out?

 

no codes?
