Last week’s fuel filler door clue for the Blazer was a bust. Everyone piled in on it, right from the start. But I’m going to give the win to CyCarConsulting, because Hank limited the time frame too much by saying it was an early-mid nineties Blazer. OK, this week, we need some different parts to look at, like under the hood. Calling all driveway mechanics; you’ve got the advantage here. Now where’s that can of starting fluid?
