check that fuel pressure!!!!! bet you the pump went bad. after a possible 20 yrs it finally gave up

i have fuel pressure the blue wire that lead from the computer to the injector is dead for some reason cant figure out why changed computer same problem

Does it need to read oil pressure for the fuel system to work? There are some systems like that, but I have no idea if yours would be that way. If so maybe the oil pressure sensor went bad??
