    Since it was free I figured what the heck it would be a good one to keep in the truck until I figured out the accuracy was questionable. It read a little off from what my neighbors fluke read. I use his as a standard since it is on a calibration program where he works. I spent $49 at home depot and it reads the same as his fluke.

    Yeah, it's new-ish. I'm crossing my fingers for a Fluke for my B-Day coming up.

    delcowizzid, I am looking at the wiring diagram for the truck and see no (power relay) going to the injectors. I see (eng-1 fuse 20A, and ecm-1 fuse 20A) but no relays.

    Thanks,
