2002 GMC Sonoma 6 cyl Four Wheel Drive Automatic 126000 miles
How do you check for faulty fuel pump. Can't hear the pump run when the key is turned on. What should voltage readings be at the fuel pump.I have the 5 volts when the key is turned on, but can you check for 12 volts if the truck doesn't run? If so which wire should it be?
have the same problem?
