Does your 1.7 make a knocking sound just at starting? It happens just before the engine starts to run. Mine has always done this & I can't find anything loose or anything hitting anything within the engine bay. Normal? Thanks.

Are you hearing the fuel pump's initial pumping sound to prime the injectors with gas, before the engine even fires up? If so, that is normal.
