Sequence of sounds at startup - ZR-1 Net Registry Forums

I've noticed the ABS making noise only after beginning to roll from a stop (accompanied by ABS ACTIVE telltale lamp).

If the ZZZZZZZZZZZZ fuel pump sound is not heard, it's probably because the rail is already primed (due to recent engine running or prior key-on prime cycle). Or a dead fuel pump, fuel pump relay, etc.
