TXCASE801 Posted January 24, 2009 Share Posted January 24, 2009 i have a 77 280z with a doner 93 t/a w/a lt1 and am using the t/a wiring harness. ok about noon i got the ignition switch wired up and had the engine turning over. started working on the front lights but could not get the head lights working. i then turned the key to listen to it spin over and nothing. i checked and im not getting power thru the yellow starter relay. i can jump pin 87 and it will engauge. so i have a gm factory 93 t/a manual and a datsun wiring schematic. I DO NOT HAVE A JTR BOOK OR THE TPI BOOK. do i still need these book and does anybody have a clue why the the starter quit engauging when the key is turned????? im fixn to start drinking and smoking....... thanks a bunch for your help. jj ps does the jtr or the tpi book help with all the wiring using a gm harness?? if not where do i get the best info on how to do it.

gvincent Posted January 24, 2009 Share Posted January 24, 2009 There are wiring diagrams on this site showing what all the ECU pin out you need to use. You have to search for them, I have this info on my computer at work I can send it on monday. The fuel system interlock setup and VATS is the hard part I found, that and I'm still dealing with the VSS. I'll figure that out once I get the car running again. Long story, rod spun bearing or a crank bearing gave out while still on jack stands! Greg Quote Link to comment Share on other sites More sharing options...
