Jalex, I meant to ask about the earthquake... Hopefully all is well with you and yours!

I'm not familiar with the Pertronix ignition, perhaps someone else is familiar with Pertronix and can jump in. I doubt it will help but I did the ZX dizzy swap that's wired like this;

@RobotandtheRoad On your fuel pump issue... You can convert to an electric fuel pump. All 240Z's come wired for an electric fuel pump. You should find a couple of wires just dangling back by where the fuel gauge sender is. Then in the wire bundle up by the passenger footwell you should find some blue tape around a connector with a green wire and a black/white line wire. You can jumper that connector with an inertia switch (crash protection) and it will power up the wires at the tank when the ignition is in the On position. I just turn my key to On for a few seconds to prime and then start the car. MSA sells cover plates for the mechanical fuel pump and also electric fuel pumps, but you can find these pumps on ebay for much less than MSA charges.

Don't know if you have ethanol free gas in your area, I do have it here in Utah and use it exclusively in my 240Z. For winter storage I put in a can of Sea Foam with a full tank of gas.

My guess is it has nothing to do with your distributor, plug wires or coil to distributor wire. More than likely it's something to do with the way the Pertronix ignition is wired. In the stock 72 240Z wiring diagram the primary coil wire goes through the tach which is also where the turn signal indicators are.

I did get a new cap, however the old cap and rotor were working. I changed as I felt there is better conduction with the brass cap and rotor. https://www.oreillyauto.com/detail/c/standard-ignition/standard-ignition-distributor-cap/std0/jh66 And a brass rotor. https://www.oreillyauto.com/detail/c/masterpro-ignition/masterpro-ignition-distributor-rotor/opi0/23773/v/a/16440/automotive-car-1972-nissan-240z?q=240z+distributor+rotor And I notice that my car has 4 different wire looms that I tagged in my photo above where I only see 1 on your car.

Are you missing these spark plug wire looms / stays that I boxed in green? If so, it's time to start hunting for some, they are normally included with the car.

My RPM's pretty much stay steady idling at the lights. Don't know if they do ethanol blended gas in Panama? I do have ethanol free fuel where I live and I run it in my Z. The gas is more stable without ethanol and the car is much easier to start when cold (you probably don't have cold in Panama).

Jalex, I was out cruising today in about 90 degree F temp in stop and go traffic. When I looked at my temp gauge it made me think of you. I run a 3 row Champion radiator with electric fans 160 degree thermostat, also converted to Evans waterless coolant back in 2017 as it has a much higher boiling point which keeps steam bubbles from forming on the cylinder walls. Also run a ZX electronic distributor and coil with Taylor plug wires and coil wire, resistor deleted. ZTherapy did my SU's back in 2017 and I've never touched them since I put them on the car. Car runs just fine in heavy traffic with my temp gauge looking like this. This is about as high as it ever gets, but it's never been an issue with the way the car runs. Engine is original, never been out of the car.

Jalex, With your car we never know what might happen next. 😎

Should be just fine.

I've done LED on all external lights. One thing I found is that LED bulb color should match the color of the lens it's going behind. This will give you maximum brightness. The other thing about going all LED is the reduced stress on your harness as this substantially reduces power draw.

Myself, I was 34 When I got me first CD player for Christmas 1984 and the first 2 CD's included were DSOTM and Flim & the BB's - Tricycle. By that time I had collected over 1,000 pieces of vinyl and yes, it's taken care of, always jacketed, cleaned on every play, decent turntable and cartridge. Once I heard these CD's I never looked back! I now have over 1,800 CD's that are now ripped on my LMS server. I'd guess somewhere between 1/3 and 1/2 of my vinyl collection has been replaced on CD. I'm no audiofool but to me CD was a very noticeable improvement over vinyl. There were other conveniences with CD... Just play the end of the track "Runnin' Down A Dream" on Tom Petty's "Fool Moon Fever" CD.

Yes, the person that "invented" the headlight wiring upgrade and the "Alternator upgrade Kit" (I'd also recommend this) for 70 through 72 240Z's is Dave Irwin. MSA has pretty much taken over the continuation of Dave's most excellent wiring mods.

The MSA harness is plug n play. See my post immediately ahead of yours. Also, if you plan on LED headlights you will want the MSA harness as it changes the power / ground arrangement on the headlight bulb connection.
