Hey there today I gonna show you how to solved Relay noises won't start and what's the Reason

Let go here This is a Grounding wiring Earth Problem in Many Honda Cars why when we plug in OBD can start because Electric system Relays got Grounding from OBD scanner and then startup


There is 3 Main Grounding wiring Earth in Civic and Crv
