Question about 1992 Lexus Sc 300
The car will not start. the usally fuel pump sound is missing when the car is turned on. I checked the voltage at the fuel pump and found it to be 9.8 volts is this normal?
HI, i would check the fuse. it could be almost cooked and half able at this point. I would also check the fuel pump relays voltage as well. if the voltage at the relay is the same, the ground may be corroded or broken.
In this case, pull the connector apart and look for corrosion(green goo) and clean it with electrical contact cleaner. If none found, check continuity of the ground wire.
If the ground is ok, replace the pump.
