Fuel Pump problems
I have a 2008 Dyna SuperGlide. Bike ran fine 2 summers ago, I garaged it Winter 2023. when i went to bring it out last year the fuel pump wouldnt prime or turn on. I couldnt remember if I added the fuel stabilizer for winterizing, so I ordered new pump and put it in. It still will not power on or prime. I've checked all the fuses and veerified good. I went and bought new relays still no go. So now I am down to tracing wires and checking the run switch. Then a buddy said his V-Rod did the same thing and it turned out to be his ThunderMax auto tuner. I downloaded the logs and sent them to Thundermax and they said everything looked fine from the logs ... I've never had any issues with it, and cannot find the old HD ECM to swap it back out. Theres a change its gone for good after I moved after Divorce back in 09. So can't I just flash the map or update or replace firmware to resolve issue on the Thundermax? If not does anyone have a used Thundermax for Dyna for 2008 era for sale? Open to any other troubleshooting steps, I have already read a thread on here from back in the day and tried all those steps too.
