  1. When it comes to electrical I honestly have no idea what to do, what do I need to check? Do I use a multimeter? Does the ecu need to still be hooked up while im testing?
  2. To be honest I cant find the fuel pump relay. Even with the FSM. I got another ecu on craigslist, (crapshoot on whether or not it works) that I'm going to put in in hopes that's the problem. If that doesn't work then I have a factory refurbished ecu at work that I can buy for $200 my cost. I don't have any blown fuses, and the fusible links look alright visually. I want to go through and reground everything as well, I just don't know where to start. The car is about 45min away from where I live and work so it makes it difficult to get to it. Plus it doesn't help that by the time I get off work its already dark. Ah well, suck it up, throw on the old jump suit and grab a flashlight. I'm going to try and get there after work today.
  3. I put all the old parts back on. The only new part was the relay. By the other stuff I meant a cowl, window regulator, stuff like that. The mechanic plugged in a node light to the injectors, had me crank it over and it didn't light up. I still don't have power to the original wires for the fuel pump so its still on my switch. So its getting fuel all the way to the injectors, but doesn't actually inject. The only thing left that I think it would be is the ECU, or the fuel pump relay. I cant find where the fuel pump relay goes, even with the FSM. I do have a couple of wires unplugged but I cant find where they would connect. I don't know. As much as I don't want to, I'm thinking of just taking it to a shop...
  4. Ok, so after a few days of messing with it, I had my girlfriends brother come out to look at it. He is a certified mechanic. He plugged a little LED light into my injectors, it didn't light up so I'm not getting any power to them. I found a guy out a ways from where I live, and bought an extra EFI ECU relay from him for 5 bucks, (along with some other miscellaneous parts) and I'm going to put it all on and see if it makes a difference. Wish me luck and happy holidays if I'm not back on before then!
  5. I put my old pump back in, and started to think... If my fuel pump relay is bad, would that kill the wires to the pump itself? That way, even though I'm running a switch to the pump, the computer reads that the relay is bad still, so in turn the computer could be reading that the pump isn't working and running a fail safe and killing the engine to prevent damage. I just ordered the relay from work and it will be here this afternoon. Its made by Standard Motor Products if that makes a difference. It said in the description that it was OE replacement so it should work. Gah, 5 o'clock cant come quick enough!!
  6. Its a '76 280z, and yes I used the old wiring with the new pump, and got nothing. Then I put both the old and the new pumps straight to the battery, they both fired up. That's when I ran the new wires. Last night I decided, eh, what the hell, and put the old pump back in, went to try to start it and the battery didn't have enough juice. Its been sitting on a trickle charger all night so when I get off work ill see if that fixed it. I hope that maybe the new pump just didn't have enough pressure. The fuel is fresh as well, no rust in it anywhere. Trust me, I took a bath in it... Noob question but by FSM do you mean the Field Service Manual? I honestly don't know and I feel dumb for asking. But honestly, I would rather feel dumb for asking a question vs going without the information. Thank you
  7. When I say I hit the switch, I'm referring to the switch that I wired to my fuel pump. I turn on the ignition, turn on my switch, and I can hear the pump from in the car. I know the pump is working because I pulled the line off the fuel rail after the filter, hit the switch, and it sprayed fuel into my bucket. Let me back up a few steps.. I was sitting at a light, started to go and the whole car jolted, died, and wouldn't start again, thus ending with me pushing the car a few blocks. Before I bought the new pump I put the old one straight to the battery, and nothing. When I put the new pump in is when I discovered that the original wiring was bad. That's why I ran the switch. I don't think the AFM, wiring, and pump could all go bad at the same time but hey, what do I know. I haven't measured the fuel pressure yet, (money I just don't have at the moment), and I know that's Z cars are very finicky when it comes to pressure. 36psi I believe. I was told by some guys at work to pinch off the return line on the FPR and if it ran a bit longer then that's what is bad. Do you guys think that could be a possibility? Thank you for your help
  8. So to start, my fuel pump went out a day after I picked up the car (go figure). Now she's been sitting for almost a week and a half because I cant figure out what is wrong with her. I bought a new fuel pump from work, put it in, just to find out the wires to the pump are bad. So instead of running new wires all the way back I just ran the pump through a switch that I hid for security reasons. Long story short, I hit the switch, fuel pump fires up, I can hear it inside the car, but she wont stay running. The Z will start for a second or two and then die again. Am I not getting enough pressure? Or do the original wires that go to the pump have to be plugged in because of a sensor or something? Please help and thank you in advance. P.S. I miss my Fairlady...
  9. my pump went out about a week ago on my 76 280z, (day after I got the car, go figure) and after some work I found out the wires to the pump are bad. also found that out after I had bought a new pump. I hooked everything up through a switch that ive hidden for security reasons. I can hear the pump when the switch is flipped. now the car acts like it wants to start, gets so close, but then dies. is it possible I didn't get a pump with enough pressure? the pump is a carter P70304 pump. it says it pumps 30 gallons per hour, but I have no idea on the actual psi. ive read that z cars need at least 36psi but I don't know if the carter is sufficient. any help??
