Same problem with my 300ZX, but I have also lost the temperature indicator, amp and so forth. This is even after replacing the dash panel once.
Digital Gas Gauge problem for me also. The digital trip odometer goes out sometimes as well. Other than that no problems.
If there is no light on the dash the problem is with the power supply which is under the drivers right knee.
Same problem with fuel light
I don't have any problems with my 1984 300ZX. It's a great car.
Hi, I just bought a 1984 300ZX and the problem is the same digital gauge does not work. does anybody know how to fix it. also the digital odometer works and sometimes it doesn't. does anybody know where to get anew or used dash for it this one has cracks.
I have the same digital dash problems with my 1984 300ZX, and in addition, the radio works only intermittently even after a costly repair. I am considering purchasing a used 1991 300ZX, but can't seem to find much on the net about its reliability.
Write danielmail at rogers.com and thanks.
I just recently bought my 1984 300ZX, but the digital dash does not work. I think it may be a power supply problem. Is this correct?
I have a 1984 300zx too. 5-speed (non-turbo) I bought it new from its original owner and have now had it for about 10 years. The digital dash has always been a problem. As a previous poster pointed out, it is the power supply/computer unit under the right knee which is the problem. You can remove it and solder each point (there are over 200) and it may work again. Mine did, but only after I put in one that I pulled from a junkyard. The only other problem I have is a 'quacking' sound which comes from the right rear wheel. The wheels also tilt inward. / I have noticed that most all 300zx's of this year do the same. I am in the process of restoring it. It is drivable, but needs a little cosmetic work. Is there a place on this site where we can post pics or our babies?
Z Lover Too,
This may help with gas gauge problems:
I also have a 300ZX, actually I have 2. And in regards to a previous entry, both of them the right rear wheel tilts inward from the top. Is it just the suspension or an alignment problem. Also, one is an '84 and the other an '87.
I have a 1984 300zx, the dash is electronic, and the RPM gauge isn't working!!! I also have another 300zx same thing, but with t-tops and a non-electronic gages. Can't I just use that one? Or is there a another way to fix it because I like the electronic dash. Please if you have a comment send it to
My girlfriend has an '84 non-turbo. It's only got about 90k on it and it still runs great. But yes, her speedometer doesn't work either! It works about 50% of the time. The other 50% she's supposedly going the top-speed, lol. Her speedometer is not digital though.
Hi, I'm taking the motor out of my 1984 300zx and replacing it with another motor from a 1986 300zx.
Any tips or pointers would be greatly appreciated.
Also I have the same problem with my gas gauge, just thought i'd throw that in there.
