Runs about half a second on ether. Can't hear the fuel pump when key turned on. I did the fuel pump on my last Blazer, a 1989. That was about five hours work.
The parts house says about $275 for the new fuel pump, comes with the gas tank sending unit, and can't just order the fuel pump. That's the one year warranty one. The Bosch one is about $50 more, and lifetime warranty. Can have a Bosch for you in a couple days.
What's involved in replacing such a fuel pump? Pull the tank down, and lots of work?
