Ok. I just took a bike ride to S Hutchinson island to noodle on this. I think the problem is with the fuel delivery circuitry for the following reasons:
1. Fuse blows while preheat is held down and starter is cranking. Sometimes it actually just starts but it now always blows with the preheat engaged. That rules out the shutdown switches and the start relay/starter.
2. Bypassing the shutdown switches with jumpers makes no difference. Another data point in support of #1.
3. The point of shutdown varies. Sometimes it actually started and ran for a few seconds. Sometimes it shuts down as soon as it tries to start.
My next idea is to systematically disconnect the fuel delivery circuitry and hope I get to a point where the starter keeps on cranking without blowing the 8 amp fuse.
