Default Please! 2000 S-10 2.2L, will not start when cold.

My S-10 may or may not start once it gets down to about 10 degrees.

The check engine light is normally on. The codes are smog related but I don't remember exactly. I had them checked a while back.

Here is the unique part, with the engine off, key on, the idiot lights are all on like normal, including the check engine light. But, when I crank the engine, if the "check engine" light stays on, it starts. But, if I start to crank the engine and the "check engine" light goes off (while cranking), then it will not start. It cranks fine but does not have spark or fuel. Until the "check engine" light comes on, then it starts immediately.

I keep trying it over and over. Then when the light comes on, it fires right up. And continues to run fine. The colder it is, the worse the problem. When it gets close to 0 degrees then it may not start no matter what I do. Unless, I put a blow dryer under the hood for 20 min or so. Then it will usually start. Please give me some ideas.
Thanks!

Engine block heater?

I do have a block heater. And that does help the engine crank faster and longer, but it does not help it start. Not unless I put the hair blow dryer under the hood and warm up something on the "outside of the motor", I guess.
Thanks for your idea!

Default Solved

I noticed that sometimes when I wiggled the key hard that it seemed to help. I changed the ignition switch and it has started right up ever since. I have started it several times in the single digits not below zero yet. And now my check engine light is off while driving.
thanks for your help
