Yeah, A pressure gauge is a handy tool but on modern engines you need to be able to talk to the computer. You can "rent" a lot of test equipment these days but a real scan tool isn't one of them. (At least not at the stores around here) BUT there is a reasonably cheap tool now being sold that does do quite a bit. Topdon Ultrascan Elite, From the reviews it seems like a handy tool for a DIYer who wants to go farther. If you don't want ABS or Airbag coverage the Ultra is a bit over half the price.
