    Electrical problem...ignition not switching car off

    Alright guys I'm at my wits end with this. I have an M50V swapped car, my harness was done by Dave Markert at Markert Motor Works, he did a bang up job and the car has been running flawlessly for the past 3k miles. However just recently things have gone awry. First, the vehicle would not start on occasion. Never when cold, but after driving for awhile. I would go into a store or something, turn the car off, come back out, attempt to start and it would act as though the starter was not engaging. If I jumped the car, it would start right up every time. I was curious if it could have been a bad ground, but I never had time to replace them before the issue changed, and is now in it's current state. The car will not turn off. Once started, engine will not cut off, I can even pull the key out, and unhook the battery. To get the engine to stop running I have to pull the main relay, however all of my accessories (sans the radio, interior lights, etc) will remain powered. To include the cluster. After this started, I replaced all of my grounds, and replaced the ignition switch. i've inspected the main harness under the hood, nothing seems to be frayed or touching. I can't crack this egg guys, any ideas?

      Yea Dave I have, with a junk yard relay but none the less it still remains on when I pull it so that makes me think that's not the issue

        Could this have something to do with the DME or possible the c101 connector? I've been doing some reading and pin 6 apparently controls the power supply when ignition is turned on...could something have gone faulty with that connection?

          Okay so...I just ripped the entire car's dash apart. I think I've looked at the whole ignition/dme circuit and I cannot figure out what is backfeeding the power. Even when I pull the main relay...cluster remains lit (except the CEL), and everything also stays lit when I unplug the ignition switch. I checked my aftermarket stereo, it looks fine (all it is is a head unit.)

            peel back the C101 and see if somehow pin 6 or 7 have somehow made theirselves in contact with a solid red wire.

                Well the car is finally working after going through utter hell to figure it out. It turns out it was a bad unloader relay and a very temperate main relay. Both working together to piss me off. Unfortunate that I ripped the entire car apart only to find out it was that simple.

                Im actually convinced Dave is just magic. Because he called me and suddenly the car started working. Thanks for your magical powers Dave. Hahaha.

                    Unfortunately my heater/ac doesn't Work now and neither do my turn signals...hazards work but the signal switch doesn't do anything. Haha if its not one thing it's another.

                      remember what i said about the unloader relays controling your blower motor and windows? :D
                      You plug the hazard button back into the right plug?

                        Sigh. Probably not. Are you talking about the hazard switch into the correct plug?

                          Because the hazards work, as does the window defog and audio balance dial
