You most likely have one or more dead cells in your battery?
Test your battery! Use a battery hydrometer.

charge battery and test cells again to make sure all 6 cells reach a full charge.
If not return and exchange the battery.
I always purchase my replacement battery's at my local dealer.
Use your multi meter to measure the output voltage from you alternator when you finally get your vehicle running. Should be 14.4 volts.


It is also possible that you have a defective starter? Where did you purchase it? There is a lot of cheap shyt being sold to unsuspecting car owners looking for a bargain.
Reading your post lacking punctuation can give one a headache, but if a 30amp fuse blew you have a problem.
Dis anything get wet?
Good luck

 

Had an issue a few weeks back where when I would try to start it up it would turn everything on for about a quarter of a second, and then black, nothing, no power at all. So I picked up a new battery, tore into the car to pull the old battery, when to disconnect it, turns out I was an idiot when I added a power wire onto the positive terminal and it had come loose, tightened it up, all was good, and now I have a spare battery. Check your connections, and then track down the grounding strap for the engine to ensure it isn't corroded through or loose.

 

There is a switch at the top of the brake pedal assembly. It allows power to the starter when you push the start bottom and depress the brake. Check to make sure the switch is working and it has not come loose.

 

This would definitely prevent it from starting, but if everything is going dark it's likely something different.

 

Everything going dark is usually just a dead battery.
