Ticking sound when the ignition is on accesory position

[Jimi_Hendrix]

I hope this dosnt get me the flaming of the century! Lol!...
 
.... but!
 
When i get in the car and turn the ignition to the accesory position - just before the final one that cranks the starter motor - i hear a sort of relay clicking sound and then a continuous tick a tick a tick a tick a tick a tick from the under the hood.
 
I guess the relay click sound is the fuel pump priming or something, but should there be a continuous tick until i crank the engine? Because when the car is running this ticking stops.
 
Is it normal? I tried a search but got no helpfull results.
 
 
 
Yes i am a little bit of a dunce BTW :Giggle

noisy fuel pump relay probably just the primer for engine start
