Car with MSD keeps running with kill switch off

[Anonymous]

Sorry if this has been discussed before but my search turned up nada.

I have an 82 Regal with a BBC, MSD dist and a 6al.

The first issue is that I have to turn the key several times before it will turn over. When it doesnt I get a series of clicks like the solenoid in trying to engage. When it does turn over it goes like gangbusters.

I think this may or may not be related to the second issue:

The car will keep running after I turn the ignition key off. Even when I hit the kill switch on the bumper it continues to run until the carb is out of gas. I have an electric pump controlled by a switch so I don't completely run out of fuel.

Any help would be greatly appreciated as I am trying to get this car ready for a race and it needs tuning time more than troubleshooting time wasted.

Regards,

John

1. Sounds like you need a starter, maybe?

2. How isi the car grounded? Does it have a full ground cable?

3. How is the alt wired into the system? To the switch or where?

I had the same problem with my MSD the fix is to splice in a diode in the brown wire coming off the alternator, which is back feeding the MSD and and giving you the no shut down deal. As far as the starting I would look at the ignition switch on top of the column.

Thanks guys I will clean up all my grounds and splice in a diode.

I think I actually have a diode in my toolbox. Good to be a packrat sometimes

If you need to eliminate a backfeed to the MSD from the alternator, your kill switch isn't wired right. The kill switch should break the positive circuit from the battery to everything else in the car.

Someone else was asking about that too.

I HAD TO WIRE THE MSD AND THE FUEL PUMP TO THE OFF SIDE AND THE ALTERNATOR TO THE BATTERY SIDE OF THE DISC. SWITCH

Any specific reason why?
