9V? Should be alternator voltage, about 14 volts. There is some decent voltage drop across the line but it should still be at least 12 I would hope. At any rate, there will either be some or none as far as trouble shooting the pump is concerned. And a pump is either good or dead, not really any in between there. Upgraded pumps are only 100 bucks, and if you dont go bigger than a 190 you wont NEED an aftermarket regulator.

Re: Fuel Pump
The alternator going shouldnt affect anything else. Injector cleaner would clean junk out of the mechanical parts of the injector, which has nothing to do with anything electrical the alternator may have afected, so I'm not sure I see the connection there. You still havent given any symptoms or reason why you think its the pump or the injectors. What is the original problem. Help us help you. Speak english, and provide all of the information
 We want to help, naturally.
