NaudiS4 Posted April 10, 2014 Report Share Posted April 10, 2014 Has anyone had any experience with a KA harness into a 510? I got a great looking "universal" style harness and the damn engine wont start up. I have no fuel pump, injectors or spark. I am starting to believe that it is my ECM because I have power at the fuses on the new harness but nothing else. There are only 2 grounds, a constant and an ignition signal....All of which have been verified as good. The car ran fine with the jalopy of a harness before. I sent them the ECM and am just curious if it could have been bumped or something in transit. I am currently waiting for a call back from them to continue troubleshooting. Any ideas? Anything I could be missing? Thanks guys. 69 510 S13 block and head S14 distributor and AT ECM No CAS Starting circuit is separate from the harness (engine will crank) Quote Link to comment
Icehouse Posted April 10, 2014 Report Share Posted April 10, 2014 I would put a test light on it and see if you are still getting power when the engine is cranking. I run into that problem a lot.. You should also have a start signal wire (orange wire at the ECU). Quote Link to comment
NaudiS4 Posted April 10, 2014 Author Report Share Posted April 10, 2014 Test for voltage at the harness fuse box when cranking? Or at the orange wire? Quote Link to comment
q-tip Posted April 10, 2014 Report Share Posted April 10, 2014 Power to the ecu, as well as the orange wire, there is a convenient "how to" in the "how to" section......... 1 Quote Link to comment
