Resistor? Relay? Confused...

So i was putting my hood back on my 73 Nova and didn't have the power turned off on the car. I grounded my socket wrench against this box twice sending some sparks around the bay. Since i did that, the car has acted funny, after it heats up to running temp it will begin to cut out like its starving for fuel? No pings/knocks/backfires just continues to cut out like its not getting spark. The Ignition box and coil are both connected to this resistor/relay. I cant find one like at any parts store.
Could this be whats causing my problem? Is there a suitable replacement for this? The alternator and fuse box, fans are all connected to this problem child.

My ignition system a mallory hyfire VIIIA ignition box and mallory comp 9000 dist, and mallory promaster coil.

Are you sure that is a relay? It looks like a connector where a bunch of wires are just tied together. A relay must have a control wire to turn it on. Usually it is a "hot" wire. They do make some that work off a ground wire but they are somewhat rare.

Try a picture from a different angle so we can see more.

Drivers side or passenger side?

Looks like a junction of some sort and it also looks real rusty. I would disconnect the battery and take that mess apart. Clean all the connections and put it all back together. When you shorted it out it may have made a bad situation worse when you drew all that extra current through it.

I was doing a search on how much it would cost if i FUBAR my coil and saw this thing. The small white resistor that comes with it. Not on my car...this is the only thing slightly resembling the white box.

If it is a relay it still needs a control signal. The Wire that runs to the fuse box must be the control signal. It should be worked by the ignition. Is it off when the switch is off? Are the electric fans your heater fan? Engine fans? All the other wires look like they supply the power for the relay and tie the other things togethor.

Yes it is worked by the ignition. When i turn it on everything else fires up and everything seems to connect at that point.

Could i have messed up this relay by grounding it out?

I would appear the relay only works the fan? The wire you have marked fan should be the only thing that this relay should work. Trace it back and see it the wire only goes to the fan. The wire loom can be opened up a little to follow it.

This car should not have a electric fuel pump, so that should rule that out. I have learned to unhook the battery when not troubleshooting wiring and some electrical problems. The hard way.

I don't know anything about your ignition setup, but it could have got messed up.

there is a fuel pump and an inline fuel filter. Runs 5psi when idling but cant really see what its running when the car is rolling down the road...

Where all the positive wires connect on the first picture there is a plate under the relay that connects into the box like the plugs for the fan.
