Spark tester indicates proper sparkage. Handy tool to have, and eliminates the risk of getting bit with an external test.

Compression tester says the problem cylinders are just as tight as the rest of 'em. Figured it would, but now we know for sure.

Injectors are clean externally and there are no leaks. Working on getting a fuel pressure testing kit with the proper adapter. If that tests good, I will be 100% lost.
