Zed Head

The white 240Z automatic didn't do so well. But a couple of Z's did very well. Strange. The 1977 280Z won the day. https://bringatrailer.com/listing/1971-datsun-240z-358/ https://bringatrailer.com/listing/1973-datsun-240z-310/ Big wheels... https://bringatrailer.com/listing/1977-datsun-280z-150/

Interesting article on that Z car web site. I've never seen them on a car shown on the web. Seems like they would have popped up somewhere. Something for which to keep an eye or two out. https://s30.world/articles/the-s30-240z-sports-option-competition-nismo-adjustable-suspension S30.worldS30.world - The S30 / 240Z sports option / competition /...The S30 / 240Z sports option / competition / NISMO height-adjustable suspension

Anybody else get this message when they logged in? Makes me wonder how Google knows my CZCC.com password. How does that work? Of course, big tech knows all.

Adding to CO's simplified test method, if you don't want to contaminate the injectors since you're planning to return them. Use the Nissan-verified human-powered pneumatic pressurization method.

What would you use to check for a pulsing signal?

You could also just reconnect the fuel system, leave the injectors out, pointed where you want the fuel to go, and turn the key to Start like you did with the noid light test. A couple of key turns should tell the story. Edit - don't forget that stuff can get sucked in to the open injector holes in the manifold if the engine is turning.

That would answer many questions. If you disconnect the small wire to the starter solenoid you can turn on the fuel pump by turning the key to Start. That will pressurize the rail and injectors. Then you can leave the key at On/Run and tap a ground wire to the coil's negative terminal. Every third tap the injectors should squirt. That will test the ECU and ignition system and the wiring, plus it will squirt a minimal amount of fuel. Watch out for sparks. Six empty soda bottles is a handy way to contain and collect the gasoline. Or you can disconnect the ECU, leave the key on after pressurizing the system and ground each injector's pin. That will open each injector. Each injector has a pin in the ECU.

If he has 6 noid lights I'd plug them all in, crank it, and see what the light show reveals.

When you say "wont fire" do you mean that you had fuel connected and they don't squirt, or the engine won't start? Or are you just going by feel in your hand? Injectors don't really "fire" so it's not clear what you're describing. But, if the original problem was the electrical connections you should be able to reinstall the old injectors. They might be better than the new ones anyway if they're Nissan originals.

A basic 1971 240Z. https://bringatrailer.com/listing/1971-datsun-240z-358/

Something different.

Tempting. https://maps.app.goo.gl/UT2jK545fAAYwcQB7

Word police here! It's not clear that everyone is talking about the same measurement. Also, not clear that any of the measurements are from the car body. The holes.

This might be interesting. Nissan calls that mount an engine mount. Looks like the auto mounts are different from the manual mounts. https://www.carpartsmanual.com/datsun/Z-1969-1978/engine-240z-260z/engine-mounting

Another modified 280Z. They seem to do well. It has the VG30E V6, edit - actually VG30DE, like my old Pathfinder, but the more fancy version. No driving video, I don't get how anyone could list on BaT and not have a driving video. Just weird. The seller has a long list of past listings too. Maybe it's a sales technique to get people to keep coming back. I feel manipulated. https://bringatrailer.com/listing/1976-datsun-280z-115/

So, is this a good "restoration" or is it more a revivation? Wrong brake line material and color, wrong head, wrong wheels. Did the Australia cars not come with the anti-resonator in the exhaust system? Doesn't have one here. Are right side drive cars valued differently than left side? Still curious about the buyers for these cars. What are they looking for?

It's still odd that this car does not have the usual 200 - 300 pictures, for what it is. 107 pictures. Seems like a candidate for an S30.world restoration.

Here's a clue.

Why? The seller did not describe it. You haven't verified that you've seen it. It had a 280Z engine in it, many of which came with five speeds. Who can say that the 280Z five speed wasn't installed? The head has been changed, so one aspect of originality has already been lost. Saw your comment on BaT. Feel free to verify that you are certain it's the FS5C71-A. It looks like you might be assuming. Of course, the seller should be doing this, unless you are representing him. It's what the Comments section is for.

My mistake, I must have confused it with a different car, the red 71, which does not have the original engine. Plus the fact that it was removed once, when the 280Z L28 was intalled. Still not clear which five speed it has. "where it was refurbished in the early 2000s and subsequently fitted with a 280Z-sourced engine. The factory 2.4-liter inline-six was later reinstalled with a high-compression E31 cylinder head," https://bringatrailer.com/listing/1971-datsun-240z-357/ I'll try to fix my error:

That 1970 #99 car seems like it's seen some use/abuse from a collector viewpoint. Engine not original, not clear which 5 speed it has, the seller apparently doesn't have spellcheck. Doubtful that it sells. https://bringatrailer.com/listing/1970-datsun-240z-147/#comments-anchor

It's a square shape by design. The small one is a seal, and there's a bigger one that is an insulator, probably meant for vibration and heat. You can probably get them at your local auto parts store. The small one is very important, since it's an intake system seal. p.s. amateur tip: it's tempting to try to assemble the rail and injectors as a unit then slip the whole thing in/on to the intake manifold. But it's actually easier to install the injectors first and slip the rail in to the hoses. https://www.oreillyauto.com/shop/b/fuel-delivery/fuel-injection/fuel-injector-seal-o-ring-kit/ee721b9bfdb5/v/a/6637/automotive-car-1978-nissan-280z

There are a couple more - https://bringatrailer.com/listing/1971-datsun-240z-357/ https://bringatrailer.com/listing/1972-datsun-240z-396/

I tried to post a midly critical comment about the 290 HP 2+2 but BaT moderated it away without posting it. I was actually giving the guy a chance to explain the weirdness of his car. It looks kind of like a con/scam at the moment. No way it makes 290 HP. But BaT filters out any comments that are even mildly critical. Cheers and happy talk only. It used to be a place where a potential buyer could get some good feedback about a car. Now it's all caveat emptor. Tending towards eBay level. Shame.
