  1. Morning all, 76 280z owner here. Just wondering if anyone has been able to source male/female electrical connectors that came on the factory gauges and interior harness? Thanks!
  2. Alright, Green on the plug was a no go. I did however temporarily rig it to a switched to a switched green I had inside the cabin. 14v immediately on start and she turned off as soon as I turned the key off..Problem solved, thanks again!
  3. I'm diagnosing her now. I think I found a green in the old plug that is switched power and I'll see if she wont turn off.
  4. Thanks NewZed! It's easy to find a 12v source that comes on with key in the ON. Unfortunately, I cant seem to find one that gets 12v at ON, but turns off after car starts. Any suggestions?
  5. Hey guys, Recently completed the internally regulated alternator swap on my 76 280z. I utilized a brand-new alternator from a 1983 280zx NA. I followed the directions from atlanticz, specifically the part for the 1976. The issue I am having is the alternator will not start charging the battery until I rev the engine over 3.5k. Once I do, it maintains a constant 13.8+ and works perfectly. I began testing and noticed the bottom plug to the "T connector" has zero reading at all times, including in the ON position when it should have 12v. I believe this is called the "L" connection. From what I believe I have gathered from searching, this is some-how tied to charging lamp, but also the excite for the alternator to start charging? If so, I have removed all stock gauges and went with speedhut gauges. Is it possible that the lack of a charging light is causing a break in the connection and causing this issue? if so, any suggestions how to work around this? Thanks so much! p.s..The new gauges also eliminate the parking break indicator, so I just cut the yellow wire under the passenger seat to solve the battery drain issue that is specific to the 76.
  6. Bunkhouse, It sits well over 12.5 volts, gives every indicator of a good battery.
  7. Hey guys, Been dealing with an issue regarding starting for a while now. I own a 1976 280z, which struggles to get started but runs fine once it is (separate issue all in itself I am tackling). The issue I need help with today is the quick drawing of my battery while attempting to get it started, I almost always have to use a jump pack to assist. The battery is a couple year old optima red top that once off the trickle charger is around 13.6. It also has new battery cables, reman starter, new ignition switch as well. I can really only crank it for about 15-20 seconds and the battery becomes basically dead without the assistance of a jumper pack. While searching for answers, a couple posts have suggested a possible grounding issue, so I cleaned up the battery to starter ground (top bolt of starter) and the main body ground above the battery. Other than that, I am at a loss for what is causing this large draw. Any suggestions would be great! Thanks again!
  8. Newzed, this indeed solved the issue! Bent the tiny rod just so slightly and now the pump stops when stalled. Additionally, it solved the continuous pump running problem while in "on" position. Thanks for your help!
  9. Thanks Zed, I will try that. Is this the only thing that controls the safety shut off of the pump? The pump continuously runs in the "on" position prior to turning it over to start as well. I believe it was determined that is correct on my year, can you agree? Thanks again
  10. Hey gents! I own a 1976 280z, in which the previous owner swapped out the engine for one from a 1978 (N42 head, n42 block). Additionally, the fuel system has been modified to use a walbro external pump with a palnet fuel rail, with an after market FPR. The issue I am having is after I force the car to stall, the fuel pump continuously runs and does not turn off as it should to prevent a humam BBQ! I did notice that the 78 requires a 2 blade style oil pressure sender, and the 76 a bullet style. Currently, there is a bullet style connector on it. Would this possibly be causing the pump to run continuously due to the wrong sending unit? I am at work but I believe the wire leading to it is a single green. Any suggestions would be great!
  11. Thanks for all the suggestions guys. Newzed, I have an aftermarket FPR, without a check valve currently. I suspected this may cause an issue, but I always allow 30 seconds(ish) before cranking for the pump to prime. Other than that, ive replaced all senors related with NOS and adjusted timing/replaced cap rotors ect (she runs great when I get her going).
  12. Great idea thanks! I will get around to that shortly. If this works, any idea what may be causing the pump to stop pumping during the turn over?
  13. Hey guys, Own a 78 280z. I am having the issue of a "cold start", when its not "cold". Whenever I want to start the car initially for the day, it takes me 4-5 good rounds of cranking to get her going. This happens at any temperature outside. I feel like the fuel pump may be shutting off once I begin cranking? Any ideas what may be causing this? Thanks in advance!
  14. Most were too loose, I cant say by how much, i just corrected. The bucking/stumbling is more accurate description then "rough". Ive read small things like pedal adjustment/replacement and throttle linkage repair or replacement may help, yet I feel its more deep the these adjustments.
  15. Appreciate all of the great ideas. I had originally adjusted the valve lash. Drove the car about 70miles. Then issues had arouse on the trip home (loss of power, backfiring out exhaust). I checked valves again, appeared to be slightly off. I adjusted again to cold setting of .008/.010 and started her up again. I was able to eliminate the intake backfire by advancing timing to about 13BTC. Took her for a spirited drive, no issues. Car just seems to have a rough low rpm driveability, bad boy wants me to pedal down. Wondering what would have caused the valves to go out of spec so quickly?
