1979.

The way I understood it, it cuts the advance in 4th (and 5th in the 5 speed) and allows the advance to work in the lower gears. Isn't that what your attachemnent says?

Keep in mind that he's looking for an EFI fuel pump.......

Ease of removal...next time.

Purchase some allen head screws to replace the original screws. Also, before you pull the injectors, make sure that #6 is getting a signal. It could just be a bad connector.

But that is a C10/230 intake setup.....strange. Thinking about it, I take back what I said about the engine 'never having fuel injection' as that would go with the manifold. I wonder how they got a hold of those non North America parts? And to go from a turbo to a 2 bbl carb? Talk about a downgrade!

I had a 78 280Z and a 79 810. They both had the 'simpler' check valve and neither one ever gave me any problems. 12 years and 6 years of use respectively. I have seen a few threads on this site about bad check valves. I've never seen the one that you initially linked to. I still have an original check valve (17014-N4225) that you can have for postage if you need it. It works fine and I doubt if I'll ever have a need for it. Let me know.

That's not "Mexican Engineering". That's a non USA version of the L engine. That would explain the E30 manifold, the Hitachi 2 bbl carb, and the valve cover. Look at the engine number on the block. That engine is likely out of a Cedric 230, HGC10 or one on the other non USA sedans. Looking at the head I can see that that engine never had fuel injection....

That's correct.

This link shows the check valve that I'm used to. The part noted as 17065. I've never seen the one you linked to.

The lower one in this picture is the "Chrome Z". (Thanks to kats for the picture)

I've done business with these guys a few times in the past. They appear to have one and it's pretty resonable: http://classicgarage.com/nid242628clh.html

Let me see; by 1971 I was on car #8 or #9 if you count one I had that never ran.

I always liked that color (510)

That would be a neat trick to adjust the MAF since a 1979 280zx doesn't have one. That, and the fact that a MAF sensor has no adjustment. I wouldn't suggest adjusting the AFM (which is really what you mean) without some way of reading the results of the adjustment.

You're not on my ignore list. I was just blowing off steam with that comment. I tried to help you earlier in this thread though my experience is not with 280ZX's. I wasn't trying to 'rain on your parade', I was just curious about the other things I asked about. That's all.

No need for you to be a smart a$$. I'm just saying that in all my years of dealing with these cars, and that's well over 40, I've never heard of Nissan having any interest in keeping records of their older vehicles. I'm done with this.......

I don't buy that but that's okay. It's not my car.

So you didn't 'do a carfax' as you said. Out of curiousity, what Nissan dealer would keeps records for a 31 year old car?

I've never heard of that. How often is (was) that actually done?

How would you have been able to run a Carfax on a 1980? Carfax requires a 17 digit VIN which didn't start until the 1981 model year.

I agree! Nice work.

Your car is a 280ZX so this may or may not exatcly apply in every detail but on a 280Z you open the hood, remove the wiper arms and blades, remove the four screws that hold the cowl, lift it up slightly and pull forward.

I'm not arguing. Everyone knows what they are comfortalbe with and what works for them. I'm just throwing it out there (like everone else). It becomes somewhat anecdotal especially when we start discussing what someone else recommends. Keep in mind that my vehicles don't have to survive freezing winters so what works here for me may or may not be as effective in Minnesota or Midwest, USA or in any climate different than where my experiences are based on.
