On the 08 & 09 Camelotís, Contessaís and Scepterís go to the rear run panel inside the gray box. At the rearward end of the PCB is a terminal bar with white wires connected to it. The screws come loose. When the second one to the bottom, going to the starter solenoids, is loose, it will intermittently not start.
Iíve found several of these loose. While in there, see which screws are loose, back them out, reseat the wires and tighten them back up. Then finish snugging the all.
Put this on your annual maintenance routine to tighten, along with the wires in the transfer switch and circuit breaker panel.
The VEC-1 fuse that blew could have been caused by that loose screw. Take a look.
VEC-1 fuse feeds one of the wires in the plug to the right of the fuse. The wire is printed with VEC-1 all the way to power the ignition switch. Then the start wire (I forget the wire label) runs back to the plug connector on the PCB, and the trace goes to the black terminal strip.
