Hmmm. A head scratcher.
If the EFI relay is bad, you will be able to crank it but it won't fire and start (no power to the ECU). Since your relay is "noisy," I would start by checking that. That is why you have a multimeter.
Crossing battery terminals, of course, can damage lots of stuff. So if the EFI relay is good, you need to describe your problem. Will it fire, chuff along for a bit, then quit? Will it fire, but keep going? Will it crank, but not fire at all? Will it not even crank, just relays clicking? Or when you turn the key, do you get silence? All of these things are "engine can't start," but they all point to different causes.
