FI light & no start

[TrapperAH1G]

Need some help. Without going into too much detail and humiliating myself.....was working on my '01 Nomad, standing on the right side, when it started "leaning" towards me and falling over. Grabbed under the tank and the seat to try to stop it (handle bars were off), and the tank "got loose". Got the bike back up and on the kickstand. Put it all back together, tank still loose (rocks from side to side), and tried to start. Everything seemed to be okay until I hit the start button. FI light is on and there's no power. Assume something is loose under the tank. Hopefully a connector that I can simply plug back together.

Anyone experienced anything similar? The shop manual I have is not the correct one for the FI model so the procedure for removing the tank, and the connectors under it, aren't covered.

HELP.
