Z32 N/A starts than turns off. - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hey guys. I have a 1990 300zx N/A and I just changed the spark plugs and now when I turn it on, it starts than dies right after. I made sure that everything is plugged in correctly and bolted down, but now I am stuck.

Sorry if this has been posted before.

Thank you.

It might be a bad vacuum leak.

How does it idle? is it jumpy?

Also could be a fuel problem but I would check vacuum first.

With things like this you need to see if your car is getting fuel (this means gasoline and air), compression and spark. We can eliminate compression because you said it starts.

(I posted this same comment in your Z chassis thread, but more people will see this here, just in case they are having similar problems)
