You need to get a meter so you can read actual voltage. I've seen digital multimeter meters in discount stores, not very high, better than nothing.
I don't know what testing you have done? I'd have to start from scratch. Make sure the battery has a full charge. Use a gage and check fuel pressure, engine cranking, right now, I don't care about the initial prime. Some of the national brand autostores used to loan out a fuel pressure gage, if you don't have one. Check for applicable trouble codes, at the least, you need an obd2 code reader. If it turns out the problem is other than a fuel issue, me and you are just spinning our wheels. A no load test on a fuel pump isn't worth much, I've seen pumps run just fine on the bench, wouldn't run with a load, though.
In the diagram, the gray wire at the relay, carries voltage for the pump. If you unplug the relay and use jumper wire with inline fuse from battery to terminal for the gray wire, the pump should run, no need to use the key.
