Is it normal for my 03 stock diesel to make a ticking noise when the key is turned on before I start it? It lasts a couple of minutes then stops. It sounds like it's coming from the front of the engine but is hard to pinpoint exactly where it's coming from.

Thanks Dean

mine does this too, last time i bothered to look for it i thought it was coming from under the relay box in the engine compartment ... not sure tho

i remember this being discussed before and its normal. i think its from injectors

OOPS

Yes, it is the fuel system getting ready to feed the horses!!!!!!!

IIRC its the #1 and #6 injectors bleeding the air out of the system.

Thanks, I guess I won't worry about it then.

All so your fuel pump set beside the fuel filter it comes on when you turn the key on so it could be what you are hearing.

i have never heard of that, can you go into the process a little? or are you making funny??

From what I understand it just fires the injectors and the air thats in the system gets pushed out. There is no fuel pressure so no fuel comes out... That's what I read at one point.
