A buzz-test is the common way to test each injectors "action" by cycling them, one at a time, so you can listen to them and determine two things.
One is weather they're getting power at all (like from a bad harness/plug), the other is that they each have a similar sound (you can actually hear a "bad" one buzz differently than the others)
Any of the good diesel scanners will do a buzz test for you and quickly determine if the connections are still good. You need to find somebody with an Autoenginuity, Snap-On, Ford, or other professional scanner. It should also be able to monitor the ICP / IPR values.
