Default Help me Please

I have a 2005 Harley Dyna Low Rider with an S&S 117 on it was having the problem of it feeling fuel starved when I was keeping it at a speed it would throttle up fine it would idle fine this problem got worse until it was falling flat on its face when I would try to keep it at a regular speed all my research direct me to the fuel regulator so I figured since I was in the tank I would replace the pump the filter and the regulator which I did this now changed the problem to it won't idle and barely wants to start and only will if I give it a lot of throttle. I have now replaced the throttle position sensor it has made no difference when it's cold it's backfiring a little and it doesn't want to start. I am at a loss any and all help will be greatly appreciated.

Take your gas cap off and turn the key. Can you hear fuel spraying or just the pump running?

Fuel,spark and air.
Might want to check air delivery. Also make sure the tank is venting.

​​​​​​If you can hear both then I'm guessing the internal fuel pipe to the petcock has sprung a leak. Had the same problem recently. The plastic pipe wears off the inside of the tank so your fuel is just circulating inside the tank.
