SOURCE: how to change a fuel pump in a 2000 chevy blazer
Good Day,
I am assuming that you have the 4.3L V6.
The fuel pump is always a pain on trucks becasue you have to remove the tank to gain access. The pump is bolted in on the top side of the tank. I hope it doesn't have a full tank of gas as it needs to be drained(re-use when job is complete). Not to mention pulling a tank that's full of gas very heavy.
See this link for an overview:

Here's how you test the fuel pump relay, and fuel pump:
Fuel Pump
Also see figure 4 which is digram 3 from this link, this is the schematic on the fuel pump, the fuel pump's hot wire is tan with a white stripe, if you can test the voltage of this wire you can confirm it is not an electrical problem.

Also be sure to releive the fuel pressure before servicing

Let me know if any of this is jibberish to you and I can clarify further.
Good Luck again, and feel free to ask anymore questions.

Best do a fuel pressure test. Should have chg. fuel filter from the get go. The only other filter is on the end of the fuel pump in tank. Bad gas and dirty gas will plug up fuel filter, hense burn pump up.
