I have a 1984 S-10 Blazer since it was new
almost 29 years ago

Explain how a new fuel pump doesn't work

I only had that once on my 1965 corvette
A new pump had been assembled with the
diaphragm outside on a couple holes,a quick fix

You must have fuel to the carb & thus you need
to take the carb apart & work on that

So far I found that NAPA is the only source for
a carb kit

the dash sound's like a fuse, check the fuse box under the hood and in the door jamb on the side of the dash, also check your fuel filter and fuel pump, im betting on the pump because i have a 2001 chevy blazer that has had two replaced and it has 233000km on it!

underhood relay center has fuel pump fuse

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/thomas_c50676e836a18949

Unless there is an access panel inside the vehicle above the fuel pump, you will have to remove the fuel tank in order to access the pump. Do not forget to replace the fuel filter. Partially clogged fuel filter is one of the causes of a failed fuel pump.

try replacing the fuel regulator,or is the oil cap on tight?the fuel regulator works on base vacumm

Hello, There is no fuel pressure relay. If you mean fuel pump relay, you can find this by opening hood, look towards driver's area, on the firewall just below the cowl vents you should see a relay with 5 wires going to it.

check for spark by removing a sparkplug

Check the fuse under the dash. Did you replace the inline fuel filter? If not, you could loosen the line going into the filter then turn the key to the on position. The pump should run for about 2 seconds then the relay should kick off. Turn off the key for approx. 5 seconds then cycle key back on and the pump should cycle again. If you get a 2 second burst of fuel each time then the pump is cycling. Install a new fuel filter and check the grounded wire by the tank. Hope this helps. :)
