Blazer wont start
My blazer wont start when its cold out. I can sit there and crank the engine over all i want until the battery dies, but it wont start, it seems like its not getting spark. So i talked to a friend of mines dad (mechanic for the local pontiac dealership) and he said it sounded like the Ignition Coil. So i replaced the coil, and the blazer ran fine for a few days, but today it wont start again.
I was told it had a tune up by the person i bought it from, but i'm not sure what all he did in the tune up.
Anyone have any ideas?
