N/a engine runs when key is switched off

Hello. I got a problem. When I switched the key ingition off and key is out of barrel. Engine still runs. So I thought the valve switch. But when I pull the wire off its connector engine stops. That tells me. Small current still feeding the stop valve. So I checked with voltmeter and even removed the speedo fitting thing to access the black fuse box. All checks ok and no live feed after switch is off. I cannot trace where the live feed comes from.

At the moment. The only way I turn engine off is by removing the key and switch the fan heater on and it cuts So by doing that it removed the feed. Strange

Mine did this and it was junked up inside, stripped it cleaned it put it back together and now it's fine, the plunger wouldn't drop down and cut off the fuel

Mine does this and i have wondered if the fuel stop selanoid is faulty but wasn't sure

Hi. I have changed the stop solenoid valve no difference. Then when it was running the wire (white) to the solenoid I pulled it off and it stops the engine. That tells me it is not the solenoid issue. I think maybe alternator back feed. But I trace the power and it not from alternator. Aargh!! Lol.

Ignition switch?

Flat. The actual switch ? U reakon. ? Could it be that simple ? Lol.

worth a try in case something is not right withing the switch itself, maybe take it out and clean it up and inspect it befroe shelling out on a new one, i dont know how much they cost

I swapped mine for a britpart one, it would only stop when I pulled the wire off, you could take the key out and it would still run, so out of desperation I stripped and cleaned the old one put it back on and it worked fine. The 'plunger' on the Britpart was a different shape and although it would stop with the wire pulled off it wouldn't with the key switched off??

Yeah I replace my alternator thinking it would cure it but didn't
