CLICKING QUESTION IGN SWITCH ON POS.

Truck has been doing this since I bought it so I dont know if its normal or not. Summer time I dont pay it any attention, but I know it would do it if I were to stop at the ON position before cranking. Anyway when I turn ignition switch to the ON position for the glow plugs to heat up there is a fast clicking noise that comes from under the hood. Maybe does it till the GP light goes out. Is this the GP relay clicking because of a low battery? Or something else? Truck cranks fine, but havent had batteries checked for sure. Could be low enough the relay is cycling rapidly.

I meant GP control module not relay........Or is this injectors buzzing before startup?
