You need to do a fuel pressure test on it. You also need to test the injectors w/a noid light to see if you have pulse to the injectors.

Is this truck carbuerated or throttle-body injected? If carbuerated, I'd put in a new carb kit...and be sure to replace the accelerator pump. Ethanol in gas today wreaks all sorts of havoc with older vehicles because the rubber and plastic parts manufactured back then were not designed to deal with the problems caused by ethanol. After rebuilding your carb, buy a product called Seafoam and add it to your gas tank at the rate of 1oz per gallon of gas. It will partially offset the problems caused by ethanol.

It is call a Throttle Body Injection, that is why you see wires and electrical components. You stated that fuel came out of the fuel line with little pressure. It could be that the fuel pump is weak, bad injectors, or fuel pressure regulator. Have the fuel system tested to determine what is the exact cause.
