Hey hey; I run an automotive shop and do general and high performance stuff - a lot of Holley Dominator/Terminator stuff, and some basic LS swaps; I've got a customer's LS swapped Solstice in - it was put together and running at one point, but somewhere along the line it started having issues. It was at another shop for approx 18 months and they weren't able to get it figured. Once I got into it, it had all sorts of harness issues - apparently it was a professional harness, bought buy the owner. I'm not sure I'd say it was professional anything - the first problem were numerous bare wires in the harness that, depending on how the harness was moved, would pull the 5V ref down to 0, or moved another way, feed battery voltage into the 5V line, into the ECU. Moving on, harness completely gone over, cleaned up and verified, and it runs well, no codes other than the cam/crank not learned - I haven't learned it yet, lol. The issue I'm having, is the ECU won't give me 12V out on the X1 26 wire - I have the trans set to Man in the tune, and the Clutch Position Switch disabled (until I can verify that bit is tied in properly). If I use any of my scanners, I can see the data in the ECU and Key On, the Ignition parameter is on, when I flip the key to Crank, Starter Relay Control Parameter goes from off to on, I can hear at least one relay in the box click, but no power out of the #26. I did check to see if it pulled a ground, instead, but no dice. As I said, I'm more aftermarket EFI, but I do know that that ECU might have various OS's that can change the pin out; so I'm wondering if someone has put a different one in it, or if the ECU got janked from the voltage issues it was dealing with. Is there a way to tell from the OS number I get in HP Tuners, what that software is originally from, so I can look up the actual wiring by the vehicle? That way I can be sure I'm looking for the starter output in the right place? Sorry if it's a dumb question, but I'm gonna ask it anyways. Thanks for any help....
