I recently changed my battery now blazer won't start. It does nothing. No lights no clicking NOTHING. Before I changed the battery truck ran and started fine. I've cleaned terminals. I've checked fuses. Everything is good. I'm at a loss now. Please any info besides check the terminals and fuses. Like I said it started and ran fine before.

 

Starter wire came a bit loose? Makes no sense the lights or nothing would come on though. Can you stick your old battery in and see if things work? Can you try and jump it and see what happens? I would assume the battery wires are nice and tight?

 

I'll see what it does when I try to jump it. I'll let you know the outcome. Thanks

I forgot to say that it won't go into gear with key in the on pos. Is it because of starting issue I'm having?
