So this random 7-8 seconds of cranking is still baffling me.

I traced the culprit to the starter relay and the fuel pump relay, which is Mercedes part No. A002 542 1319.

I have a question.

What caused the sound of cranking to behave different?

Normal perfect sound should be: clok...vroom, or clok..clok..vroom.

This is how cranking sounds after I changed out the relay.

But it lasts for 3 day, before the old disgusting cranking sound comes back:

Char...char...char...char...char...char ....(7 seconds if not more)...vroom..

Why?
