The very best spare relay to have in the glove is a gutted old faulty relay that has pins 30,87 and 87b all hardwired/jumper together. If you do this you will instantly power up the DME and the Fuel Pump the very minute you plug that test relay into the harness. Of course you can't leave things like this but in a pinch it will get you home.

I have exactly this in my glove box at all times. It can even get you out of other potential issues with the ignition switch and such.
