I can't think of anything in there that would affect starting. There is the brake and clutch fluid reservoirs, the wiper motor, the heater fan resistor, that's it. More likely water traveled from there into the main compartment and affected the fuse panel, or additional flooding caused other problems.
Beyond the usual ignition switch and starter parts and wiring, the Scorpions had a 2-relay fuel pump relay system. One relay powered the pump when the starter is cranked, the other relay powers the pump when the key is on and the oil pressure warning light is non illuminated. These relays are in the front right of the engine bay.
