A Haynes manual will help a lot. Here's how to check the fuel pressure if you get a gauge.
1) Remove cap from pressure test port located in fuel rail. Connect Fuel Pressure Gauge to pressurefitting.
2) Start vehicle. Pressure should be approximately 31 psi(2.1 kg/cm
2) Start vehicle. Pressure should be approximately 31 psi(2.1 kg/cm
�� ) with vacuum hose connected to pressure regulator and 39 psi (2.6 kg/cm �� ) with vacuum hose removed from pressure
regulator.
3) Check fuel pump flow rate. A good fuel pump will deliver at least one liter of fuel per minute with fuel return line pinched off. If fuel pump does not pump adequately, inspect fuel system for a plugged fuel filter or filter sock.

LONG overdue update
Ok everyone been VERY VERY busy! I checked the pressure. The pressure was very low.... like 14 or so. I purchases a Fuel Pump from AutoZone.
STUPID ME accidentally cut the wires of the existing fuel pump. Once i pulled the old pump out i found out that the rubber hose had fallen off the fuel pump. *FACEPALM*!!! Needless to say i put new pump in and it fixed it.
Now i have another problem...... It sounds like it is missing every like 45 secs. It has new plugs, cap, and rotor. It doesn't seem to be lacking and power. What is next?
Thanks again guys!!!

One question..... What is that? I am trying to figure out what the rusted out piece is called. The one the spring is sitting on and the one the shock is bolted to..... Thanks!

Oil pressure is more of a reading of the shape your engine is in as opposed to if something is wrong with it. Ya know unless it's Really crazy.
And I got the 4 hole injectors from a guy on the forum and it was only 72 bucks
