weird start when it's really cold

[buzz11]

hey guys. Lke the title says..my cb has a weird start when it's really cold out. It happens usually in the mornings or when the car has ben sitting there for hours. So i go to turn the key to start the car..but it does nothing til about 5 seconds later, then it starts up normal. So I have to turn and hold the key for about 5 secconds til it starts. The car starts up perfectly fine in 30+ degree temperatures. I checked around the battery for any corrosion and its pretty clean. The battery seems ok, although I havnt tested it out yet. I searched the threads and i can only find similar problems, nothing exact. I'm thinking it could be the main relay? Any idea guys? much appreciated

You'll have to determine if the issue is due to a lack of fuel or a lack of spark. The main relay would result in a lack of fuel. However, they usually only fail in hot weather, not cold.

Batteries are known to go weak in the cold, so that would be my first thought. Have it tested, or if it's old, replace it. Do you have a sealed cell battery (like an Optima), or is it a traditional battery with water chambers? If it's the oldschool style, then make sure there's water in there.

So are you saying it doesn't turn over(crank) for about 5 seconds? Or it turns over but won't fire for about 5 seconds? Big difference in diagnosis and repairs.

I believe it's a traditional battery. I was thinking of replacing it since it is old. thanks dev.
It doesn't turn over for about 5 seconds. After that, it THEN cranks normal. Sorry for the confusion.
