My car won't start. Everytime I tried to start it nothing or no sound would happen. Now the mechanic is telling me that the fuel pump is not working and needs to be replaced. Could this be possible. I would assume it would be some type of electrical problem.
CVO 4/30/2012First, check the battery and starter cables for their tightness or free of corrosion and physical damaged.
See this Starting system simplified diagram. Have a help from an assistant to crank the engine, use a 12 volt light tester or a digital voltmeter, apply it to the starter control circuit.
If there isn't no light or no volts, then the ignition switch is the culprit.
If there is light or 12 volts and the starter isn't cranking, then the starter is the culprit. Have the starter to bench test for free at the local auto parts stores.
Note: a 3/4 charge battery is 12.50 volts
A discharge battery is 11.75 volts.
A battery under a cranking load and it is reading less than 7 volts,it will be a recycled ( junk ) battery.
