There are numerous reasons this question needs to be a little more specific. What exactly is going on when you try to start the blazer? Is the engine trying to turn over but you only hear a bunch of ticking and then the ticking stops, if so then you need to replace your starter. If you just turn the key do the dash lights still come on, you may have a low, or dead, battery. Does it start but will not run after you put it in gear? Maybe you have a fuel problem or are in severe need of a tune up.
Take the blazer to a local autozone to have the battery tested for FREE! but the blazer would not start if it sat for a couple days or so. also it would start hard, but once it started it would run fine.
No, it would not start.
My first guess would be the fuel pump is at fault.

Cheak fuel pression in the morning.
It is probably in need of new spark plug wires.
In French, the word for blazer is "blazer," and it is masculine. Therefore, you would say "un blazer" when referring to it.

Your 1996 Chevrolet Blazer may not start due to a faulty ignition switch. The electronic fuel pump may also be faulty and need to be changed.
yup
I would suspect a faulty fuel pump or fuel pump relay.
