You mentioned LED. They're the equivalent of a one-way valve and will only pass power in one direction. Any possibility it's a direction issue with the bulb? Can the connector wires be reversed?

Is this Ebay seller the "California Datsun" that I've seen warnings about on these forums? Since MSA no longer sells the rear speaker box for a 240Z I was thinking of buying this one. It looks like what MSA used to sell.

Didn't know the 260 was factory. My 73 electric pump was added by the dealer. I did my own on the 240.

The 240 and 260Z's came wired for electric fuel pump. If your car had the dealer installed electric pump they would have also added a couple of relays into the circuit that are documented in a separate tech bulletin that's somewhere on here. If your car never had the dealer installed pump the wires are there for an electric pump. I changed my 240 to electric pump and buil my own "tray" for the pump and then found the plug up in the console area that you jump across the 2 wires in the plug to activate the circuit, it is keyed to go live with the ignition switch in run. My current pump is pretty load when the car is off with the ignition switch in the run position and it kind of shifts down when it gets the loop pressurized so I wait for that sound shift before I crank. Probably 5 to 6 seconds max crank when cold with full choke and around freezing temps outside.

I have the 280ZX w/matchbox and have the same problem with the tach, mine seems to stall at about 3,400RPM but the engine runs great beyond there. Been that way for about 15 years so I pretty much just ignore it. I pretty much shift by sound anyway, more eye time on the road that way too.

I joined the "club Frontier" forum and for my intro I said "here's my oldest and newest Nissans" with this picture. The Z got almost all the attention.

A few weeks ago I traded in my 2015 Pathfinder for a Frontier Pro-4X Crew Cab. There was a poster on the wall and I said "doesn't that go with my new truck?". They took down the poster and gave it to me.

Sorry, made perfectly good sense to me after 38 years working in computers. 😁

All my CD's have been ripped and I use Logitech Media Server (Open source and it's free) on my PC with Raspberry Pi 3b+ receivers (PiCorePlayer software that's free) connected to the stereo. Music is streamed over wifi, bit perfect, to the Pi and decoded using a hifiberry HAT DAC on the Pi 3b+. With a single server I can have any number of receivers either synced or playing separate streams simultaneously.

If you need to drive it somewhere... Shut off the engine, put it in 1st gear and start the engine with it in gear. Shifting is fairly easy, let off the gas a little and it should be easy to pull out of gear and as the RPM's drop you should be able to slide it into the next gear without grinding. When you need to stop put it in neutral and stop. Shut of the engine and repeat above to go again.

Along with the pads there's rubber strips between the tank and the metal straps that secure the tank. I think these strips and the pads effectively isolates the tank electrically from the body. I think that's why there's 2 wires (240Z) or 3 wires (280Z) for the fuel level sending unit.

I had a Murano before the Pathfinder and quite liked the Murano CVT. I put up with the Pathfinder for 7 years and in the last year I could feel an occasional "hitch" in the transmission. I took it in a couple of times and always got the same answer... No trouble found. Nissan knew these trannies were probably not up to the task of the Pathfinder since they'd extended the warrantee out to 7 years or 80K miles whichever comes first. Since I hit the 7 years earlier this year I traded it for the truck which has a real 9 speed tranny. Nissan has gone to a 9 speed tranny for the Pathfinder for 2022.

Replaced the 2015 Pathfinder before the CVT failed. Picked up this new Frontier truck that's a better match up with the Datsun.

The E12-92 will work identically to the E12-80 if you only connect up the "C" and "B" connection on the top of the module. The other connector is what controls the retard, without that connection it functions the same as the E12-80. I've been running a E12-92 for about 20 years now on my 240Z and it runs great.

So starting in 1973 in the USA the model (series) year and calendar year were the same. There were USA changes to the car in '74 where the bumpers changed, but it stayed a 260Z for that year. In the USA the '75 through '78 were all 280Z's?? Wonder how many changes went into the 280Z's (and zx's for that matter) where the model year didn't change. It seems to me that as @HS30-H probably believes that it's these USA car nonsense/shenanigans that led to the "series" connotation. I'm also guessing that the whole "series" thing originated in the USA.

@Carl Beck @HS30-H You two seem to be most knowledgeable about these cars. Now back to my question. Were there USA 240Z's registered as 1973 cars that didn't have flat tops and the beefed-up front bumper?

I've been a 240Z owner since July 1973. My current car is a 12/70 build registered as a '71. I don't think I'd heard the series "n" until maybe sometime in the 1990's. I was aware from the time I bought my current 240Z in 1990 that the "series 2" changes were implemented later in 1971 beginning, I believe, with serial number HLS30-021001 but I'm not sure what the build date was for that car, looking at zhome.com my guess is February 1971. One thing I'd be curious to know is if there are any stock round top/non beefed-up front bumper cars that were registered as a 1973? Or were the emissions/safety standards tightened up to the point that all 1973 cars had the flat top carbs and beefed-up front bumper? EDIT: @Carl Beck It's kind of like having a IZCC member # 2831 showing a join date of 2017. My guess is this is really the last time I updated my IZCC membership but the join date is probably really in the early 1990's.

I'd say Dodge Ram would be at the top of that list.

At first I was thinking of doing the valve cover in red too but now I think maybe an anodized black with the raised lettering and ribs in the aluminum like they are. Then the hoses and plug wires would have a little more pop. I'm old and come from the hot rod era but when I saw the 240Z in '71, I thought "now there's a car!". Then in '73 at 22 I was able to get one, loved it and have had a 240Z ever since (probably close to 250,000 240Z lifetime miles so far). Edit: correction, probably more like 180,000 240Z miles, forgot I bought this one used in 1990, so of course it already had miles on the clock. Edit 2: I can see 9 changes between then and now but I can't tell how many changes there are between showroom and "then".

I posted in another thread on air cleaners and had a funny thought. I've not been a purist in my Z ownership which may have had an effect on my feelings of "originality". Here's a couple of shots of my engine bay, then 2015 (but it hadn't changed since 1993) and now 2022. Interesting... Then Now Yea, I changed a couple of things.

I did the ITG dual and have air horns inside. Float bowl vents and valve cover vent attached similarly to the original but I did have to drill the back plate for the vent fittings.

Sure wish I could find a Interpart rear window louvers set like I had on my '73. Install required no drilling, top had hinges and the bottom had little latches and there was a kickstand for the louvers so you could wash the window.

Since Dave's harness is good on all 240z's including 72 and 73 I would think that other than the connectors at the headlight pigtails the harness will work on 260z and 280z's if you change the connector on the pigtail to the 240z style connector (from a little google work it seems the round connectors in the 260/280 cars are unobtanium). If you don't want to cut off the round connector you could build a new pigtail to go to the headlamp.

I actually used Dave's harness on my 240z which came with a single 30amp fuse before the relays where the 80amp fusible link is shown. The harness came with a 30amp, but where I've gone LED I could probably even reduce that. Just curious what the change would be for the 260z/280z besides the pigtail connectors? Doesn't factory wiring for 260z/280z still have a single power to pin 3 in the headlamp connector and switching ground on pins 1 and 2 for Hi/Low beam switch?

On my 240z I went with this wiring diagram to take the load off the wiring harness, steering column stock/blinker switch and also change ground/power configuration for the headlamp connector itself so that I could convert my headlights to LED further reducing load on the car wiring. Here's the diagram; Once done it changed the headlamp bulb connection to this configuration allowing for the LED headlamps because the Diodes only allow power to flow one direction; The way Datsun configured the wiring connector point 3 above was power with points 1 and 2 being ground back at the steering column. I've actually converted all bulbs except for the dashboard to LED further reducing load on the wiring. If you go LED for the blinkers be sure to replace the emergency and blinker flashers with LED compatible flashers.
