Passenger side. The driver's side is just a passive jet sucking pump.

On the passenger side is a fuel pump combined with a fuel level sensor.
On the driver's side in the US there is only a fuel level sender unit.
Connecting the two sides of the twin saddlebag tank lobes is a sucking jet pump. This keeps the fuel level high in the pump side to insure you have gas available to pump to the engine.
You'll most likely want to replace the right side pump only and also do the fuel filter which is located under the car, approx in the driver's seat area.

Do you know enough to know what you are doing?

Sounds like you're on your way with some major projects!
Best of luck to you and keep us informed.

We're a better resource than you may think. Next time tell us all the facts and see if we can't help you in the diagnosis rather than saying what you intend to do to solve whatever problem.
What do you know and what do you not know about your current problem?

I just joined this Form a few mins ago and it is awesome! I hope I can get this car running it is starting to worry me, Could you tell me where the fuel pump fuse is? I've been told it may be in glove box area or under Hood on Drivers side near the firewall.

fuel pump fuse is in glove box, you can interchange it with your horn relay, test...if no horn, clearly that relay is the issue.

Open glove box and drop the fuse lid with two thumb screws.
Should be this fuse chart in there to guide you.
