Please provide details and information about this comment.

I'm still chasing a hard to find issue, and found a serpentine belt issue, so this info would be helpful knowledge.


I'd still like to hear more about this claim!

Yes, mine is a 2005 and works as yours does, but I'd still like to hear the details about this claim, even if to understand it was talking about an older model.

Seems like the Bt doctor doesnt have any more info regarding his comments? Probably just give up on any more info as to where he obtained this ? My 2001 starts and runs like a new engine, I can hear the electric fuel pump engage and the low oil PSI alarm comes on to tell me the switch is working prior to cranking.
