SOURCE: 87 CHEVY BLAZER, FUEL PUMP NOT GETTING POWER
It's your Electronic Control Module (ECM). There is a short in the computer. You're going to have to replace it. The same symptoms occurred in my vehicle, had a mobile mechanic come to my house and fix the problem. Quoted me $350 for parts (used) and labor.

Sounds Like you have a defected pump. Or the wires to it may have gotten pinched. The fuse is showing you an over load. DUE TO FIRE !!!
( Don't use a over size fuse it can start a fire! )
You are going to need to start by dropping the tank. Check all wires around the tank. You are looking for bare wires. Then remove fuel pump check all wires going in to tank & wires in the tank. Now with fuel pump out check the wires on the fuel pump.
Now you that you have checked the wire and all are were good take the fuel pump back and tell them what is going on. They should test it.

Then your problem is electrical,make a tool if you replaced the relay open the cover of that relay,there you will expose the mechanical contact of the relay stick it back in its socket trun the key on and make the relay make contact the fuelpump should go on.If it does the problem will reside in the ignition switch electrical,if it doesnt check the ECM bat fuse.should be 20 amps.

Usually a sign of a faulty pump, or a problem in the wiring between the relay and the gas tank.
You could unplug the harness at the tank to verify.
