Hello and welcome to the forum.
I believe there's a relay involved in the pump operation, hopefully someone with a GL1200 can verify that.

Yes there is a relay, the engine has to be turning before it powers the pump. The black/blue wire is the hot wire, green is always ground.

If I disagree with you it's simply because you're wrong.

The relay is under the shelter, (false tank) by the coils.

The engine does not have to be running, just cranking with an ignition signal.

Thanks for the pic of the relay, bypassed the relay to find out this pump was not good, put on another pump(number 3) now bike runs fine only to find out now choke cable has snapped ,,,Do I need to remove carbs to get to the cable end or is there another way

You might be able to get to it through the front. Not sure it would be any easier.
