I just put new points/condenser on my 72 240z, and now it has a funny problem. When I turn it over, it will fire up like it should, but dies immediately after I let go of the key. It seems to run fine at 1000-2000 rpm when the starter is turning, but I havn't held it for long because I don't want to ruin my starter. It's acting like it's not getting spark. My only hunch is that the ignition switch is faulty, but have never heard of one causing a problem like this. Also, I noticed that my radio and brake light stay on no matter where my key is turned (even if I take it out). This is also a new problem.

I have a 78 280z with no heat i tracked it down to the vacuum water ****. i have found that the vacuum is only sufficient to open the valve part of the way. i back tracked the vacuum lines to the Vacuum tank and cant find any leaky connections or hoses i checked my vacuum tank as well and it holds vacuum. i am not sure where to look next. any input would be very much appreciated.

Hello all, I have been searching and tuning and searching some more and I'm throwing in the towel and asking for help. I have a stock 73 240 with the exceptions of a lightened flywheel (5lbs taken off), roundtopps, a turbo oil pump, and just recently a zx dizzy upgrade. I rebuilt my l24 600 miles ago and have been tinkering with tuning carbs and ignition timing and it just doesn’t seem right. I just replaced the oil today from the 30w break-in oil to 10w-30 valvoline vr1. Compression test showed 150psi in all cylinders. Ignition timing is set to about 10.5. I am a newb and this was my first engine rebuild. Alright done with the introduction now to my symptoms: 1) When …

What is the difference between an R200 differential from a 280Z and a R200 differential from a 240SX? The one from the Z has a longer “nose� than the other. Could the guts of the diff be swapped and used with each other?

I am finding that a few things are not working well on my 75 280z and am not certain how I should go about tackling these problems. I have posted questions relating to this car before but it has reached a point where I don't know where to start. A little background: I bought the l28 engine from a chap a few months ago who had a 75 280 also. When I pulled the dipstick, the oil was black (Dirty) and smelled like the usual old oil. The plugs seemed to have the usual carbon build up. There was no smell of fuel or coolant. I put fresh oil and coolant after I installed the engine and fired it up. The #4 cylinder was not firing. There was spark on the plug but injector w…

Hi All, My son has a 72 240z with a L24 and dual Weber DGVs. We have been having issues with these lately. I have rebuilt these carbs and after they were rebuilt they worked great for about 3 days. When we installed them after they were rebuilt we also put on a new filter and replaced all the soft fuel lines under the hood. The fuel filter appears to be a newer one so I didn't replace that one but I did add an electric one back by the tank. What will happen is that the front carb will just stop spraying gas at random. Maybe it will run for 2 hours maybe 3 days maybe 20 minutes. On Saturday the front carb decided to quit spraying gas. The temp was maybe mid 70s. We had the…

I have a 1975 280z with stock fuel injected engine. It starts up fine but idles rough and when it give it gas it is rough as well. I put a screwdriver to each injector and the #4 injector is not clicking. I also pulled the plug wires one by one with the engine on and on #4, there was no change. I cannot figure out where the problem would be? Is it a. bad injector, ? b. stuck valve, ? c.bad spark plug, ? c.bad ignition? What can I do to pinpoint the problem? Please help.. I don't know where to start...

I was wondering what color would you call my car? The color is not recorded on the title and someone told me it was ice blue. I'm just calling it silver.

The back end of my tail housing (280-z 5 speed), where the driveshaft seal goes, is cracked and leaks gear oil. Is it possible to R&R the tailhousing with the trans in the car? I just put everything back in there after doing a engine-trans swap... I didn't notice the crack until it was all bolted up!! I really don't want to have to take things apart again! Thanks
