Re: 93 Grand Cherokee-Won't Start in Cold
Thanks Mike. I think it does have a ballast, but again, it never gets close
to turning on it's own enough to let up on the key. Also, I don't think the ballast resister would be affected by the cold like this.

Re: 93 Grand Cherokee-Won't Start in Cold
AH. I remember in college (Potsdam, NY) it was below zero (+/- a few
degrees) and my buddy was outside trying to start his car. He poured some gas into the carb and it still wouldn't start so he came in to take a shower. I look out my window (I had a great view of the parking lot and the grass where the chicks would tan) and I see this car on fire. I trotted down to the bathroom and was like "dude, your cars on fire"... well, thank GOD he grabbed his towel before sprinting down the hall to my room!! Car burt to the ground (there is not a more miserable sight than to watch firemen put hoses away in sub-zero weather).

Re: 93 Grand Cherokee-Won't Start in Cold
I lost some eyebrows in the service that-a-way. Believe me, I'm careful.

Re: 93 Grand Cherokee-Won't Start in Cold
I'd try to fix the problem as to why it's not starting. Mostly
because I had an old Austin Healy with the side draft carburetors that one of the slide was stuck open, that sucker went to twelve grand and exploded so quick. The only place I'd use it is if gasoline was puddled in the intake manifold, from severe flooding, fouling the spark plugs.
