(someone feel free to correct me here; this post is as much for my own
sanity-checking as it is an effort to be helpful)

The fuel pump doesn't re-prime the fuel system per se. When the engine is
cold, the cold-start circuit primes the system a little (read: enough to
start the engine), which allows the engine to start. Once running, the
system pressurizes fully. This is why moving the "grey" and "blue" wires
in the engine compartment allows you to start a 'hot' engine; it forces
the cold-start circuit to prime the system.

Not sure. Would that run the risk of flooding the engine? Anyone? :)
