In addition to that , there is the possibility that there is rust in the injector rail partially plugging the screens in the injectors. What are your fuel pressure readings , dead cold and hot ?

Under the dash next to where the clutch pedel is/ would be is the inertia switch , this switch breaks the electrical connection to the fuel pump(s) in the event of a crash . Sometimes the contacts get screwed up and there isn't a good connection . There is a red button you push to reset it . Try and reset the switch .
