1978 280z No Start, No fuel injector pulse
Also, your title says "no pulse" but you said that you can hear them click when you "ground them through the coil". I assume that means you're grounding the coil negative with the key on and every third spark makes the injectors click. But maybe it means something else. That would mean that the ECU is working as it should and Pin 1 is connected.

1975 280z rear coil springs
Measure from the rocker panels to the ground, front and back. There's nothing dramatic in your picture. Try lifting the back end up by hand also, I had a strut that would stick. And, if you find that you only need 1/2 inch try new struts first. The gas struts will raise the car by about 1/2 inch.

1978 280z No Start, No fuel injector pulse
Everything that you have done looks right. Very thorough. The one thing that is missing is an actual fuel pressure number. You can have squirting at 2 psi, which might not be enough to keep the engine running. It is also possible to connect the hoses to the rail backward. This will give pressure between the rail and the filter/pump but no fuel flow through the rail. I would confirm that the hoses are connected correctly and measure fuel pressure. If the rail is connected backward you'll get maximum pressure from the pump, about 90 psi. if it's aftermarket, but no fuel to the injectors. On the 78 model the easy way to get power to the pump is to disconnect the oil pump sensor and turn the key to Run. The pump will get power. It's a flaw in the system design but convenient for testing.

That was good. I posted a Twitter link to somebody mimicking Boris Johnson along the same lines, somewhere back there. Go to work, don't go to work... Can't find it now though. This seems relevant, below, overall. Something for everybody. "Per capita relative to what". So exposed... https://www.merriam-webster.com/news-trend-watch/trump-there8217s-many-per-capitas-20200521

1975 280z rear coil springs
Might consider that if the rears are sagged a lot, the fronts might be sagged a little. So there will still be a mismatch. There's always used springs too. @zKars

Nissan 400z Rumors
I'm confused. Is it a 400Z or a 480Z? 480 would actually be interesting. I can't think of any vehicles or vehicle parts with 480 in the name. 400 is common. Pontiac 400, Turbo 400, YZ400, etc. 480Z.

Nissan 400z Rumors
I was going to say earlier that "400" is just cooler looking than "370" and that's why they were developing a new model. Now it looks like they really did just pick 400 from thin air. What if the engine only makes 398 HP? I assume that that car is actually going to look more like this picture than the bottom picture.

It's a crap shoot out there, with loaded dice. Be careful what you think you believe. Leading the world in testing.

Onsted, Michigan
What will they be taking pictures of? How much will you be paying? I've found that putting the information out from the beginning gets a better response. Like "inquire inside" on a For Sale sign. You know they want too much money, so you never inquire. Just tell what you're looking for and what it's worth to you. With everything slowed down some people are looking for any good reason to go do something.. Good luck.

Would like to start a "One of these things is not like the other" forum group. Input?
I just added to the 1977 block. Looks like it could be interesting. Wikipedia has citations. Is theer any way to add citations? They could link to the Download area. For example, comments about carb heat soak or vapor lock could link to the 73-74 carb mod document.

Hydraulic vs. Solid Lifters
There's a procedure for testing them. They're called pivots. I've only read of a few problems with them, they can wear out. You can probably replace them without removing the head, engine in the car, if you have to.

'71 240Z in San Antonio, TX Area for $5,500.00
Somebody probably sent the guy a message saying "you're devaluing the market! That car is worth $20,000!". It'll probably pop back up somewhere.

This place is really just one guy. You could call him and see if he'll sell you just two. https://zcardepot.com/collections/suspension/products/coil-spring-set-stock-and-lowered-240z-260z-280z Edit - also, just thought of this, there are places that will wind you a spring. The spring data is in the FSM.

Exposed (unwrapped) fuel rails on my 240z?
Are you planning to drive the car? Download the document that shows why the heat shields were added.

Dieing issue
Sounds like the EFI harness connections got switched. Nissan made the connectors look and work exactly alike so not a surprise. Check the AFM switch. If you have a big vacuum leak it might not be staying contacted to run the fuel pump. Also, try opening up the idle adjustment screw just to keep it running. Sounds like a fuel problem, not a coil problem.

280z in-line fuse from battery cable
They're the green ones. Same as used on the headlight circuit. I've never found a good conversion tool or equation for converting slow blowing fusible links to fuses. Seems like it would be a thing but it's hard to find.

How about an Editorial Board, and a place to submit entries for review and acceptance. That would take the load off of just one person but still provide a filter for indiscriminate additions. I think that that is how the big wiki's work, kind of.
