1999 Chevy S-10 4 cyl Two Wheel Drive Manual 100k+ miles
I have checked all the fuses in the fuse box and they are working fine, but I am only getting 5volts to the fuel pump at the tank. Is there another relay that I need to check? If so where is it and how do I check it? If that is not the problem what is? Swapping out the relay did not resolve the issue. When I turn the key I get 12V to the pump for a brief period, but the pump does not activate. What can I try next. I connected another battery to the pump and it starts working, could it be the connector at the pump? I charged the battery replaced the connector at the pump. Using the new splices I checked the voltage at the wires. The combination that powers the fuel pump does not get any voltage to it. All the other combinations of wires get 12v for a second or two when the key is turned on, then all go to zero v except the purple/orange combination which gets 1.27v all the time. What can I try now?
have the same problem?
