yesterday i got a 280z . today I started digging in to it and I realized I was not getting any spark. I tested the coil which nothing happed, so I took the coil out of my 280zx and just tested if it was just an issue with the old coil but even with the new coil their was nothing. I took the distributor cap off and cleaned all of the contacts and was still getting no spark. and just to see if something was up I reconnected everything and sprayed starting fluid in the manifold and it fired up for a second then died i went to spray a little more in and their was no more spark. Anyone know what the issue could be ?

Help!! I replaced the coil and ballast resister in my 1972 240Z, and suspect I may have the wiring wrong. (ugh) 1) Can anyone verify my understanding of the wiring in my coil/condenser/ballast resister area? Please see my schematic below and let me know if it looks correct. If not, what do I have wrong? 2) Where does the wire from the coil condenser connect to? 3) There are 2 Black & White wires (1 to the coil; 1 to the resister). How do I verify which is which? Thank You! Jughead

Hello, I own a 1971 Datsun 240z stamped 6/71. One issues Im having with the car is that the entire electrical system is gone and practically all the relays. I have been looking for the same year electrical harnesses (because I'm quite lazy to rebuild the entire electrical system or use some aftermarket harness) but I've only really seen 1972 and wasn't sure if something from another year would fit into mine. If someone has the part numbers for engine, dashboard, and interior harness that would fit into my car that would be great. Any advice and information would be great. If anyone has a complete harness for the same year car that they are willing to sell that would…

Copied from my post in the ZX Electrical forum: Use this code for a 20% discount with Vintage Connections: VCWinter20. It's good through Jan 31. By the way, I had issues with checking out at their site. Apparently the cart functionality isn't what it should be. I sent an email to sales@sparckmoto.com with what I was trying to order and asked them to bill my Paypal. Within minutes (during normal business hours), they responded, and I paid for my order.

laying a screwdriver across the starter solenoid contacts is an effective way of starting my car. but it is only slightly more graceful than hand cranking a model t. i've heard rumor of a factory TSB that shows how to completely bypass the interlock. does anyone still have a copy they'd be willing to photocopy and share? or is this as simple as disonnecting a few harness connectors and inserting a jumper somewhere? fwiw, my 260 has a build date of 7/74 and all of the relays are in the passenger foot well, not the engine bay. and no, none are labeled.

Im trying to chase down why this 280z tach does not work unless the RPMs are +2000. I found that there is this capacitor that has peeled away it’s shielding. Does anyone know how to identify them? It does not appear to have any significant marking on it. It’s the little teal one.

Hey all, I did the transistor ignition unit upgrade as described here: Given this though, I have had some problems after doing it. Given that I have a '78 I don't seem to have a resistor below the ignition coil but I think I wired the HEI module in correctly. I think it is correct since it ran for over 6 months, and the last 7 weeks of that was the car being driven daily. On the 7th week though, problems began. The car became slowly harder to start taking longer and longer to crank until it eventually stopped firing all together. I have checked and the car has fuel and air, just no spark. Seeing this, I replaced the HEI. After replacing the HEI the …

It's been a while since I had to drive my '78 in the dark. The stock sealed beam headlights had me squinting the whole way to work. As soon as I got there, I ordered some 9" glass headlight housings with replaceable H4 55/60 watt bulbs. After installation and alignment, they're only a little better. I've upgraded a '95 Tacoma similarly and bought 80/100 watt bulbs for it. It was a great improvement. Can the 280 wiring handle 80/100 watt H4 bulbs?

Hi, I'm looking for a picture of the original/factory battery cables + and -) for the 240Z. I tried to find this information on internet but every cars i found have different cables... Also, cables are the same for all years, or they are different between series ? Thank you for your help.

My wipers worked erratically, then stopped completely. For a while, I was able to get them to work by slamming the hood, or rapping on the hood latch. I assumed the motor was bad, and started to research the Honda wiper motor conversion. I decided to remove the old motor and take a look before I ordered anything. After studying the cryptic wiring diagrams, I decided to try and bypass the relay mounted on the wiper motor and go straight to the windings. When I did this, the motor ran very reliably in both the low and high speeds. I took the cover off the relay, cleaned all the contacts, and it worked fine! I reinstalled the motor on the car, and it works better than…

So today I’m tearing down a points distributor to do a cleanup on a 5/70 Z. Single points. D612-52 I get it apart and there staring back at me is two advance weights and only one of them has a spring attached. Hmmmmm... Must be missing, broken, lost sometime in the past. No sign of bits laying around. Need to find a replacement spring. Go get a spare. Post Aug 71 points, but so what. Look inside, two springs, but they are much larger diameter and looked stretched out. Go look again, find that very last D612-52 that is identical to the one with one spring, open it up, and ..... One spring. No pieces laying around. Ok, is it me or are these things …
