1988 Ranger no fire to fuel pumps
I put in a New computer, new fuel relay, new tank fuel pump, new inline fuel pump still no pump turns on. I traced the wire from the subframe pump there is a plain black wire and pink and black stripe wire. Which one is positive? Because neither one has fire coming to it. I checked all the fuses and double checked the fuel relay. Still no fire at all to the pumps, except for the tank pump low pressure pump the yellow and black stripe wire blinks on the tester. Is there any to bypass it to turn on fuel pumps?
