another no start question

I have no idea what you are referring to. What do you mean "original wiring group."

You talking about power for the new gauges? If so that should be OK.

What did you do about the original ammeter connections? I assume the car cranks using the key?

If you have spark during crank, it should run if it's getting fuel, if the spark is hot enough, and if the plugs are not fouled.

the factory wiring, the plug going to the back of the original gauge pod. I had an ammeter but it was the shut style and I did not connect it back up. its wiring was part of the round plug connector that I just left unplugged.

It cranks with the key, but does not catch. the plugs have about 10 miles on them. It was running for about 2-3 minutes and just died and would not restart. It gave no indication that anything was wrong, no sounds, or anything.
