Probably the fuel pump is bad.
A 2001 Chevy Blazer does not have a carb. It is fuel injected and has a throttlebody. If the fuses and relays check okay and the fuel filter has been replaced, I would suspect the fuel pump has failed.
Dose the 2001 chevy blazer 4x4 4 door have a access panel to the fuel pump
In the fuel tank
unfortunately, it's located inside the fuel tank
Chevrolet does not have reset switches.
under the intake plenum behind and attached to the spider
Big job you have to remove the tank I think.
it something with fuel delivery maybe a bad fuel pump, filter, or fuel pressure regulator
Could be a plugged fuel filter or a bad fuel pump.
Assuming the fuel filter has been changed, most commonly a bad fuel pump.
