    There are no fault codes, I've checked the ECU already, will do again though. Swapped in three different PTUs, a friends ECU, something I don't even remember what it was, fuses, coil packs.... about the only thing I haven't are the plug wires. Gonna' buy a new set soon I guess.
    Also I took two years electronics vocational school, and a year of Airframe and Powerplant school. I know how to cut/check/patch wiring, I was just asking for someone who's familiar with the harness and plugs to give a little guidance. I'm considering doing what GTWizard (seems?) to be doing and just making a new one but yeah those pics confirmed my thoughts that it was some crazy shit.
    And I have the service manuals, but honestly I don't what it is but they make me retarded. I get lost in them most of the time.

    I'm really glad I decided to run through checking things again, because I'm gonna' look like a dumbass right here. lol Okay, when it was running the CEL was off, I never paid attention to it staying on when the key was "on" because of the four or so other lights that are on (batt, brake etc). But anyways, I checked it's codes again with an analog meter and it's #8 on the first page http://www.stealth316.com/2-diagcodes91-93.htm (two long, three short- top dead center sensor) Next problem is I have no clue where that is? Looking through the service manuals now, which btw I can read, I'm not sure what the hell I was thinking last time I tried. lol

    I've swapped all these parts in and out of that 91 SL, the kids practically my brother he lets me work on them if I need something. lol
    Why are you so confident I'm going to make things worse by doing what YOU'RE telling me to do eh? I'm unsure of my knowledge and don't want to do that, I'm not retarded and I'm capable, thanks.
    It's not getting harder, it's been months and I've not fixed it the same issue.

    Top dead sensor or other wise known as crank sensor is attached to the end of the intake cam on the rear head by the throttle body. On your car this sensor is the cam sensor and crank sensor in one unit.

    Edit: Had I mentioned before it's a '93? Dunno' how you knew. lol
    Thanks though, very much. With different codes I never would've figured they were the same part.

    If you have a 93 model, you more than likely have the 1st gen ECU, which the capacitors are junk. You can check to see if they have done damage, by just pulling the ECU out, and open it up, check the motherboard for a black substance, that you KNOW shouldn't be there.

    Well the ECU has been checked, it's throwing a code pointing at cam/crank sensor, also I just finished testing all the wires and they're all fine for both of those. Gonna' replace the sensor(s) and see if that works I suppose.
    And don't you have to have a 1g ECU in a 1g car?? lol
