hood vents

A quick test to confirm Stephen's theory is to cycle the ignition on and off (do not start the car, simply let the pump energize for 2 seconds) a few times. Fuel pressure will build up in the line. On the 3rd or 4th time, start the car.

Yep. That's how I did warm starts in my 810 when the check valve was bad until I fixed it.

It starts fine when cold and starts fine if its warm and sits for longer than say 30 mins. Also if I just turn it off and back on when warm it starts fine.

I've tried the on and off ignition before and it didn't seem to help. But I will try it again next time I think i'm going to have startup issues.

I've asked a mechanic that works on a lot of Z's and says that its Vapor Lock and hood vents would help.

It sounds like he just wants you to spend some money at his shop. I've had a number of "tech" guys tell me to bring my 280Z to their shop and they'll tune up my engine, and even add an extra 50 HP by upgrading the chip in my engine computer!:mad::devious:

I still don't think you can get vapor lock in a fuel-injected engine, unless you do a number of bad things to it.

And after Googling 'air lock' all I get is stuff related to the engine's cooling system.

I wouldn't doubt it. But this guy was pretty cool and definately Z knowledgable. Hell he had about 30 Z's from 70-90s at his shop. He seemed like the kinda guy that was pretty much a come to me when you get desperate and not just after more work. I was just stopping by for parts. I had to get out of there before I went broke!!

I drove the Z for a while today and stopped at the post office for about 10 minutes and decided to try the ignition on and off to see if that would help with the stuttering problem and it didn't seem to help at all. I'm still thinking i'm getting "Vapor Lock" on my EFI system. But what the hell do I know!!

Which vents? 77-78? Note what year mine is. I know they're open. My question was about the various different ZX vents.
