i have a 2001 chevy blazer it stopped running i dont have any power to fuel pump i switched the relay in fuse box under the hood still no power
I see the end of the 1/0 black battery cable what attaches to the chassis/frame needing to be wirebrushed clean, the bolt and washer renewed and the connection to the engine block wirebrushed clean too~ You have to have a battery newer than five years old as well...the fuel pump needs solid ground too~
It runs just fine or is chokey and slow?
The fuel pump will only run for a few seconds when you first turn the key to on then shuts off. Have you checked voltage during that first cycle? If voltage was not present then check the fuel pump fuse, if voltage was present but fuel pump is not running then you most likely have a bad fuel pump.
