Please, please, help me! Missing school!

Ok, guys I really need help this time, Friday night while driving in rush hour traffic…my truck just died felt like it had lost all power, oddly it wasn’t out of gas because I had a gas can in the bed and filled the tank until it poured all over the ground. Tried to start and it spins over but will not start.

Long story short, had an AutoZone starter and it was for a 1994 instead of a 1984 so I switched them and still the same thing. But it actually ran with the starter for a 1994 truck, only difference is the size.

1984 starter used with two shims and still nothing.

Also, had a Mr. Gasket electric fuel pump installed last month, had been running pretty good except for the drained batteries.
The guy ran the 12volt for the electric fuel pump into the choke fuse on the fuse box underneath the dash. The choke fuse is a 15amp and on the instructions for the fuel pump it reads to use 5amp max and that it needs to be connected to a switched ignition terminal. How do I find this?
I also installed a new alternator but found out it was for AC option which I do not have, so I installed the correct unit and still no start. Checked the connections to the starter and the solenoid wire needed a connector because it was just cut and twisted.

I’ve already missed two days of class due to no transportation; I don’t have the money to rent a car and no public transportation in my area. Please, help with advice on how to fix this I can’t afford to miss any more education because of this.

Info:
1984 C10 305v8 4barrel carb

Mr. Gasket electric fuel pump part # 12S (worked fine and is still pump gas to the carb because I used a bottle from the carb fuel line and it dumped a lot of gas)

O’reilly: Starter (this is the third starter I’ve installed, the other two were from Autozone)

Advance auto parts: Alternator

Thanks for all advice it is greatly appreciated!!!
