I just replaced the fuel pump and went to start the blazer.
It turned over, i used some starter fluid to get it to fire.
It would not run but you could hear the fuel pump come on and everything worked. The battery was diying and i tried to start it again and it did nothing. It wouldn't turn over, no lights, no power, nothing! Jumping it did nothing. what would be the best thing to start with. is there a fuse that could cause this, but there is 0 power anywhere.
Please help!

Thanks!

 

What are you driving?

 

it is a 93 k5 blazer

 

I would go through and check all of your connections and fuses just to be sure that it is not something simple.
