Quote: You are wired correct (& it did start at one time) and the soldered in green wire w red tracer is required for an OE type 5 pin (5 pins are functioning) ECU and it just dead ends now in the pentastar connector & that ain't causing you any problems with your 4 pin ECU & you would need that (green/red tr wire) if you ever subbed back in an OE 5 pin ECU. we will get his solved! Grab that alligator clip jumper & work backward from the coil positive primary. There is poor continuity in some connection between batt/coil pos pri cuz jumping directly from batt to coil pos pri does let it fire up
Robert, also, that green and red wire you see soldered is actually the light blue/yellow wire at the ECU, I had to extend the wire years ago to re-arrange things for the big block..
