I have a 2007 dyna fxdbi.... I bought from a friend and he does not know the security pin to unlock bike.... I tried every combination from every thread possible. Replaced battery in fob. No luck.... next I was on to replacing tssm with tsm... bike now cranks but fuel pump won’t turn on and no spark....I bypassed fuel pump and the fuel pump works. what do I have to do to get this bike to fire? I took to my local dealer to see if they could marry the (used) tsm to my ecm... they are saying bike should fire up then die, allowing them to start the process. But it seems like my ecm is still thinking thier is a tssm that is not allowing spark and fuel. Their computer on the other hand does communicate with my ecm.... I’m stumped here... and I don’t think they are the smartest techs over at my local hd dealer

 

By the way, check the fob from the original tssm, is the polarity correct on the button battery?
