Fuel Pump

i got a 92 plymouth laser...i think my fuel pump is goin and i want to check it but i dunno what the volts are suppose to be when i check the wiring...does anyone know the normal voltage that goes to the fuel pump? :smokin:

approx 9V

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.

well i was wondering if like the injectors would go bad due to alternator goin dead...cause my alternator went and everything got fuck'd with since injectors and shit are electronic u think i should add sum fuel injector cleaner to my gas and try that? cause maybe sum of the injectors got fuck'd

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.

Aite well basically when i gun the car it will jump RPMs (Due to automatic) like all auto cars and than when it gets starts boost it will juss lose power and won't go anywhere...but if u keep goin it will than jump RPMS and it will go again...kinda feels like sumone is infront of my car when im goin 40MPH hold'n it there for a second and than letting go and than hold'n on again...kinda like it's not getting enuff gas...that's my theory on things...but my friend tells me it could be the tranny slip'n which i wouldn't doubt but it juss don't seem like a tranny slip :smokin:
