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.

That’s a good idea. Might be able to jumper 12v to the ignition items directly or back at the relay board and run them hot while I engage the starter with the key.

Might just use the old R&R troubleshooting method and replace the electrical side of the ignition switch.

Anybody have any tips on the best ignition switch of the various ones available? Would like to avoid the worst of the cheap repop junk if possible
