It could be in my head but after the bike primes then I start it I swear I hear the fuel pump like it just continually is priming, its a 01 softail , 116" thundermax . its hard to start after it sits for few days , its the battery one of those lithium , shorai 480 cca , it cranks slow when cold have to try few times until battery is warm not sure I like the battery.
Isn't the fuel pump suppose to be running if the motor is running. :nix:
maybe your right , I just didn't think I would here it like it does when you turn key on?
The FP runs initially for two seconds (ECM Strategy), then while the Crank Sensor is sending Signal. Normal. HOWEVER, an abnormally loud pump may indicate an issue with the pump.
Try putting some Marvel Mystery Oil in with a couple tanks of fuel.....might quiet the pump down some. Wife's Sportster had a noisy pump at start up, worked for that.

I did the same with my softail as in MMO. It had a dry bushing squeal to it when running 10E fuel. That solved it instantly.

Ran it religiously on my Continental to prevent valve stick as do many owners. V rod sees it every now and then too.
