At this point I would take the pump out and see if the actual pump can be freed up if it is locked up. As fuel pump failures are extremely rare as Popgun says, I'm curious how long that tank of gas actually sat in the bike. Could it be years?
That also brings up the question of the injectors possibly also being clogged.
Shop around for fuel pump prices - https://www.hondaparts-direct.com/ has pump/filter/gasket for under $400.
No, the gas wasn't in there for years, I rode it a few months ago- it was possibly in there for 4 to 6 months I'm not sure. I tested the FP by hooking up battery and ground to the 4P connector- with the tank off - nothing, nada, no sound, I'm not planning to remove the FP from the tank until the new one is in hand. it's on order...

However, the same cannot be said of some other Honda forums where pumps are at high risk.
This year Honda Corporation had a significant recall/warranty effort and due to fuel pump failures affecting bikes and cages. I hazard to guess the CB1100 does not have this issue. The problem had to do with the propulsion system components disintegrating. For most of the year, Honda had a shortage of validated pumps.
In any case, electrical components do fail for random reasons and maybe jdgrego1 you are just a rare statistic. Hopefully you can remain happy.
yea, I've been a rare statistic in other regards as well
and yes I will remain happy -

Yes, Max's caution is well founded. Gas fumes, enclosed quarters, and a spark from your jumper battery could make things ugly quickly.

yep, working outside - don't want to go boom!

haha- yes- I did, and the relays, I really wanted it to be something other than a 500 fuel pump!
one point brought up by Pekingduck- injectors might be clogged- whats a good way to verify/ensure they are not clogged and correct if they are? I could do that while awaiting parts- I am assuming even if they were clogged that wouldn't 'kill' the pump, yes? no? man it would have been so much easier to just get on that pony and ride consistently...... now I know! you can bet your BP this won't happen again!
PS- maybe I can blame this on Covid19? Not riding due to not getting out, working from home, etc... haha!
