You put power from the relay to the pump, it worked. That wire is good. The wire from the fuse to the relay is bad. Your going to have to look inside the fuse panel.

    If you don't have a primer, Then crack one of the injector lines open at the injector. Crank it till fuel comes out or even starts. It will smoke until the air is purged. If you have rouble this way, you may try filling the fuel filter, then crack the line.

Check your connections. did you run the fuel pump wiring under the drivers side door sash like GM did?.. if so check for nicks in the wire or bending or cracks.. this happens.. happened to me. check your fuel pressure. 40 dollar part at an auto store. If its below 59 PSI it wont work. And blazers are very intolerable to low fuel pressure. Also try taking the negative post off your battery for a little while and then putting it back on and if you can get it started again drive around (if its safe and running decent) for at least 30 minutes to get your car computer system acclimated to a new functioning part. Did you check the fuel filter?. rule of thumb when a pump goes change the filter its always the last thing people expect because we all jump to catastrophic engine failure at the first no start moment. lol.
Make sure that all your ducks are in get my drift.. Air oxygen fuel thats the mixture you need to check all those vital parts. before pulling your head off.

At the fuel pump relay you should have 1 full time hot wire. 1 hot wire when you turn on the switch. 1 ground, and the other wire goes to the pump. Test the ground to be sure it is good. If so then jump a hot to the one that goes to the pump and see if it runs.If it does then you have a bad relay or ECM. You can swap the relay with another of the same # from tour fuse box to test it.There is also a ground on top of the frame near the filler neck, check it too. Good Luck

first off do not use a test light. use a circuit tester. what you saw as 5volts is called a reference signal. the cars computer(much like your home computer)works only off 5 volts. if you use a test light(the old kind with a light bulb.)you will fry the computer. second, are you saying the problem is still occuring after these parts have been changed?

Thanks for choosing FixYa and welcome. You should have power to more wires then one. If I were you, I would run a wire straight to the pump from the battery to see if the pump will turn on. I know one wire is for the fuel gauge. Then the out and return line, then grounds. This could also be the ECM. You should switch the relay out with another to see if that does help. I am not for sure if that is what you mean when you say the relay fuse.
