Hello everyone, new to the club. I'm working on a 1978 280z and this thing has been sitting for years. So to start out I drained the fuel tank and put new fuel in, changed engine oil/ filter, installed new spark plugs & wires. All while I was waiting for a new ignition switch to show up. So once I got the ignition switch installed I started to crank it over trying to get a start. It wouldn't start so I took off the air measuring device and tried some starting fluid. It backfired on me. I verified I had spark at my plugs. I ended up going under the car and checking the voltage at the fuel pump while cranking and I had 0 volts going to the pump itself. Can someone help …

On my last drive of this past driving season, my engine overheated. It wasn't intended to be the last drive, but unfortunately that's how things worked out. The failure was a split in one of my engine compartment coolant lines and I lost most of the coolant. I didn't know anything was wrong until it was too late. I never noticed the temp gauge creeping up and I didn't know there was any problem until I saw wisps of steam while sitting at a traffic light. And by that point, it was too late... The coolant was gone, the engine was overheated, and the temperature gauge was pegged hot. It became clear that even though I believed I scanned my gauges frequently, it was…

The headlights on our "new" '72 240Z are all but useless (especially in the rain as we're learning this week). I need the quickest route to better lighting. I have received some great advice on the subject from my original thread (http://www.classiczcars.com/forums/topic/59179-brand-new-owner-need-help-w-christmas-gift-ideas-for-my-kid/) and I DO plan to take it. I will upgrade the alternator to a modern unit and buy the headlight wiring harness (http://www.thezstore.com/page/TZS/PROD/classic10l/12-4651) that y'all recommended. But at the moment, I HAVE to address our exhaust system (setting off neighbors' alarms, etc) and I can't tackle everything at once. The car i…

I have had a few ask if there is any problem running the 123ignition with the old tachometer. To my knowledge there is no problem. However, if you do need to have your tachometer repaired there are two companies that do the conversions to add modern electronics so they will work with the modern ignitions of today. I had mine repaired in 2006 by JDO in the UK. I can't say enough good about them and their service. They are: http://www.jdo1.com/ and http://www.nisonger.com/ If you have any issues and fixes post them here.

Does anyone have any experience with this electronic points replacement? I have a 71 240z that I am wanting to replace the points with a electronic system. I have heard about replacement of the tach and distributor with a zx model. Just curious if anyone has replaced stock ignition system with a electronic system with minimal mods to the the chassis.

Hi, Does anybody have a picture of how their wires are connected on their ignition coil and ballast resistor. I think mine might be connected wrong, the engine runs but the tachometer does not work. Any help would be appreciated. Nick

Hello guys, I am in need of your help. I have searched this site and google for help on this topic ( search not too user friendly for me on this site, must not be doing something right) I have a 71 240z that was an automatic so there is some extra wiring and relay in part of this problem, I am converting to manual. Another problem is that some of the wiring was charred, I took pics and tried not getting things mixed up. The wiring to the coil and distributor does not resemble the FSM, the FSM does not have 2 B/W wires from the harness by the driver side horn I have as the following 2 B/W stripe wires- one going to the + on the coil and the other going to the re…

The other night I was driving home in the dark when I noticed my the lighting for the gauges starting to fail. Soon, all I had left was the lighting on the speedometer, and it failed shortly after that. Fortunately I had a GPS unit running, so I could monitor my speed, but I was filled with dread thinking that my parking lights also went out. I checked the fuse and found it blown. I replaced it, but still no lights. I checked the connector in the steering column. It had suffered heat damage. (Note: The wires are not sized for a 20A fuse.) I replaced the connector (Thank you, Vintage Connections!) and tested. The ammeter I had on the battery was running over 20 A…

Do you really need to purchase this brush kit to clean all the female light sockets on your 240z? https://www.amazon.com/IPA-8086-Light-Socket-Brush/dp/B00KHC651Y/ref=sr_1_2?ie=UTF8&qid=1514492241&sr=8-2&keywords=brush+bulb+socket or could you use a dremel that has a bronze brush?

So good news I got my motor in but I guess I did not get all connectors as tight as possible. The two wire connector that is located by the alternator came loose. I did not take pics when I re wired, just did one connection at a time. So now I am left wondering which wire goes where :/ Any help would be greatly appreciated. There appears to be a white with black stripe. Does this go in the horizontal position or the vertical position? Sent from my iPhone using Classic Zcar Club mobile
