I'm not sure on the Scangauge. I know guys used to like the Snap On "red brick" scanner as they're now cheap and do the tests on these trucks. I have a Matco Proscan and it works great.
Before going to far I would inspect all UVCH's for burnt connections. On a few I've done I've always pulled the oil cap and taken a smell, you can usually smell the burnt connection before pulling the valve covers. If they are OK check the engine wiring harness to the plug on the driverside inner fender. I've seen pins pull out of the connector there. If that's OK, get the scanner and buzz test the injectors. If they're coming back OK you get to dig a little farther.
Once you determine what cylinder(s) is giving you an issue you can take proper action with a compression test, swap injector between cylinders to see if the issue follows the injector etc etc.
These engines aren't that hard to work on and usually require just a little patience to work under the hood. There is many how to's on here that cover the basics.
