st0878 Posted June 7, 2004 Share #1 Posted June 7, 2004 Ya know I had a new battery laying around and decided to swap into the my 76 280z last night. You would think the old bitch would appreciate it but she decided to pay me back for all the times I've dogged her! Anyway, I put the new battery in and changed the cables to purty new ones, soldiered everything up so I would have good connections, but now it looks like either the fuel pump or injectors are not working. The starter cranks and I did confirm that I am getting spark. I'm trying to track down the friggin Fuel pump relay but I coulnd't find any reference to it in the 2 pages of Haynes manual that actually pertain to my model Z. If anyone has a picture of it I would apreciate it (Or if you could narrow it down to the side of the car that the relay resides!). Just to keep me confused they decided to make the 2 leads (one pos. one neg.) that come off the battery to the wiring harness both red. "If you can't defeat the enemy confuse them". That puts just enough doubt in my mind to consider whether to swap the 2 around just to see if I can fry the rest of my wiring harness!Any ideas on what might be wrong would be greatly appreciated!Yes today my Z is a bitch but tomorrow she'll be my baby again!ThanksEZ Link to comment https://www.classiczcars.com/topic/12091-fuelignition-problem-new-battery/ Share on other sites More sharing options...
st0878 Posted June 8, 2004 Author Share #2 Posted June 8, 2004 OK I found the problem. The black should have gone to the red and the red should have to the red and not the red to red and black to the red. In other words, you hooked the wires up backwards you idiot!
