  1. Ah ok, makes sense. Thank you for clearing it up for me. Which forum should I post questions like this in? Won't happen again, and again sorry for the confusion. Thanks!
  2. Hello, Yes I am new and don't exactly know what I'm doing. I had perceived the knowledge base area to be a place to go with questions, was I wrong? Apologies for any inconveniences.
  3. Hello! I have a late (August) 1977 280z, and am looking to buy a 1978 280z for parts transplants. However, the 78 is a 2 + 2, which I know is a bit different. I am mainly trying to replace the entire hatch assembly and windshield on my 77 280z, anyone know about the compatibility of these parts from a 2 + 2? Thanks!

    Fuel Pump Confusion

    Ah, I was actually using starting fluid while cranking it, and it didn't fire, and never ran; so I assumed there was an issue with the spark. Guess this confirms my suspicions. That or I have many more problems to find lol. But for now, at least I have fuel running through my system. ECU looks to be fairly clean. Thanks!

    Fuel Pump Confusion

    Right, I was thinking that I would need some type of resistance to not burn something out. So to my understanding, if I connect the green/blue wire to the fuel pump from the fuel pump relay, and place a jumper between the two green/blue wires as well, the fuel pump should run? Thanks! Edit: got the fuel pump to run hardwired to the battery, and had engine cranking and fuel going through it but it still didn't run. Now going to check if I have a spark and if my injectors are firing correctly.

    Fuel Pump Confusion

    Thank you so much, your explanation of the different colored wires and what they do is very helpful, and makes sense. I will reattempt to wire the pump the right way and repost any problems I may run into in this thread. As a side note, I have read about a way to hard wire the fuel pump to the battery to get it to run? Is there anything you could explain about that? Again, thank you so much. Very helpful.

    Fuel Pump Confusion

    Hello, Apologies for the picture not showing up. I had confused the oil pressure switch with the oil pressure sender, the pictures you had attached is what I was referring to. The door jamb plate says that the production month and year was 8/77, and upon further inspection my oil pressure sender has the T shape connection (I'll try and link that image). Thank you for your response!
  8. Hello! I'm a first time car restorer (late 1977 280z), and struggling mightily with the wiring of the fuel pump. I have put a lot of research into this, and attempted to recreate wiring diagrams, but it doesn't seem to be working for me. To my (limited) understanding, the fuel pump has to be integrated into a circuit with the oil pressure switch, air flow regulator, and some combination of the EFI, Fuel pump relay, or Fuel pump control relay. I started doing research into the different pins, and had found that pin 87 powers the fuel pump, so i rigged a wire into that, and connected it to the positive terminal of the pump, and grounded the negative. upon cranking the engine, i noted that the fuel pump was not turning or taking in fuel. If anyone knows a way to "jump" the pump to get it to run, or how to actually wire the fuel pump, it would be greatly appreciated!! I'm so eager to see this thing run, and all I need is fuel delivery! P.S. I have gotten the fuel pump to turn using 9v batteries, so I know that it works, and is not the problem. I included a picture of my probably horribly wrong rigged up fuel pump. Greatly appreciate any help! Thanks!
