jnh-280z Posted August 24, 2023 Share Posted August 24, 2023 Hello Datsun Z Friends, Long time lurker, first time caller. I have a 78' 280Z that I've been restoring for... years. I bought the car in south Ga in early 2014. I have a motor built by Datsun Spirit, stage 4, and I'm trying to start it finally. I have the XDi crank trigger setup V1.8. I have everything wired like the manual says, I think. I'm not getting spark. 1. I've confirmed the dip switches: u, d, d, d, d, u, u, d. 2. The trigger wheel sensor is <0.06" from the 7.25" wheel. I have a flat tip sensor. The sensor mount is aluminum and is on the left side at about 9:30 position. 3. I've grounded everything(DFU to engine block, XDi to battery and chassis). 4. I have the yellow 2 amp lead to the XDi powered from the yellow/black harness wire that is +12v run and start position, inline 2amp fuse. Spliced with a wire from 85 on 4 pin relay. I have a 10 amp fused line running to 30. I ran a ground wire to chassis and battery on 86. 87 goes to the DFU. I did the 4 pin relay wiring like so in the Electromotive manual: I have +12v going into the XDI on yellow wire when the car is in run position. I have a green light on the XDi unit in run position. When in the start position I have a red light. I'm wondering if the DFU also needs to be grounded to the battery? Can I eliminate the 4 pin relay above and try the system to see if I get spark? I am testing spark by using my timing light. Thank for any help. Here's a photo for what it's worth. Cheers, Jason Quote Link to comment Share on other sites More sharing options...

NewZed Posted October 8, 2023 Share Posted October 8, 2023 No offense, but it's highly unlikely that you have the same ignition set-up. But maybe you do. Do you?
