I'm helping a buddy get his 2000 softail springer running. It's been sitting for a while with the normal neglect issues but the initial problem is the main issue. He says the bike was running fine and just quit. Trailered it home and found it has no spark to the plugs. He did a little checking himself and thought it was the crank sensor and replaced it so we know it's not that. I have it now, and thought I would pull any codes that might led us in the right direction but Nooo. The odometer is dead, and the speedo dosn't sweep or cycle the engine / pursuit lights although the backlight for the speedo will light. I guess my question is, does the ECM need feedback from the speedo/odometer to enable the engine to start? Is a replacement speedo needed or somthing else the problem? Speed sensor is clean, have power to ecm, and coil, just no fire trigger.
