Starting six when cold, Strange phenomena Options

[gereed75]

Car seems to start normally when warm

When cold (40 degrees or below) I can get car to start hesitantly after numerous pedal pumps to prime. It begins to run when motoring starter but as soon as I release key to run position the engine suddenly dies abruptly as if being switched off. I can eventually get it to run after very persistent motoring on the starter until it begins to clear and will finally run in the run position .

It just seems that the run/ignition circuit is significantly weaker in the run position than in the start position, like maybe the run contacts are high resistance or bad ground??

Are there two separate contacts in the ignition switch?? One for run and one for run/start??

Can the switch be opened and checked/cleaned??

Thanks.

Certainly sounds like the switch,you can take them apart (tricky) but worth doing if just dirty inside.

The grease inside them gets caked up and rubs off the contacts over time causing them to wear or burn due to poor contact as the springs struggle to apply good contact .

An expensive part so certainly worth trying to fix it,be carefully pulling it apart as the parts can fly out if you remove the cover too quickly,good luck.
