Drove to Albuquerque the weekend before Thanksgiving last year.  On that Monday truck was having hard starts and was surging.  Started calling around for shops and no one but By The Book Diesel would even look at the truck until after Thanksgiving.  Took the truck in on Monday afternoon and they found the transfer fuel pump was bad -- ugh! as I know that usually takes out the injector pump too which costs thousands.  I gave them the go-ahead expecting that, after ordering parts and the long holiday, the truck would be done early in the week after Thanksgiving.  But at 8:30PM Wednesday night, the night before Thanksgiving I get a call saying the truck is done!  They busted their butt replacing the pump with an in-tank pump and getting the truck going again so I could get back home!  I got lucky and didn't need the injector pump but By The Book Diesel worked late for me over the holiday and I was able to get home and didn't miss a day of work.  Much appreciated! - David M.
