Hey thetre i put another oem fuel pump in my car today . before i put the new one in i tested the one that was in the car but apparently not working but when i tested it with alternate power out of the car it worked . can a fuel pump kinda work or or it either works or not could it run and not pump? let me know what you think thanks Greg

 

wow, that's hard to read. Does your new one work? If not then it's probably just a fuse man.

 

don't they run on certain voltage, not that it matters.
