First problem is, after she starts I can drive it anywhere, no problems, runs great. I turn it off and go to start and she won't start just spins over like a mofo, lots of spark.

Working on my 86 GT T-top, I was doing the plug wires and I noticed a wire standing out away from the harness. It's coming from the bottom side of one of the round harness plug-ins on the backside of the intake manifold (the salt and pepper shakers as some people call them). I grabbed it to follow it and it came out of whatever it was connected to with a butt connector. I have no clue where this wire goes, Haynes nor Chilton is really giving me an idea with their wiring diagrams and I'm not getting a fuel injector ground pulse from the PCM now it seems . Anyone know what this wire goes to? According to what I've seen it's the PCM ground, but when I grounded it she didn't start up. Unsure if maybe it's some other wire that needs voltage and I can't seem to find the other half

Maybe I'm going crazy and that wire is not an issue but it sure is annoying!

FYI I just put a new fuel pump, ignition module and cap&rotor as preventative maintainence =p

 

if it is orange it is the ground for the engine harness

 

Yeah, found that out after searching around the internet forever lol. Thanks for the help! Also the restarting issue was resolved when i tweaked all the pins in the "salt and pepper shakers" as per a TSB I found. Got her all up and rolling, now she's overheating at an idle. Going to try a new clutch fan for now until I get an electric fan. It's a 306 with a cam ported e7's with bigger valves and some other goodies so it probably could use a cooling system upgrade anyways!
