1991 blazer cutting a fuel pump door to access fuel pump assembly?

Try to get the pump working. Get the fuel line disconnected from the filter ( you need to change the filter anyways) and a hose into a gas can. Have several cans ready if needed. By-pass the fuel pump relay and thump the bottom of the tank to 'shake the pump' somewhat. Sometimes they will start pumping. At least this way you can remove a lot of weight from the tank before dropping it. Personally I would not be cutting holes in my floor pan.
