I'm not sure how you'd tell if one was about to go. Every injector I've heard ticks slightly (some more than others).

If you want you can "listen" to your injectors with a wooden stick stuck in the end of a plastic hose held up to your ear. Whatever you touch the stick to will vibrate the stick which in turn will broadcast the vibration (aka sound) down the tubing to your ear.
The injectors themselves are difficult to touch with the stick because they are down under the snakes but if you look between the snakes you will see the injector connector and wires. Touch the stick to the connector or the injector and you will hear the ticking of the the injector slamming open or shut.
Keep in mind that the ticking will sound different depending on where you touch the stick to the injector.
Nowadays, injectors are so well made that it's usually not necessary to replace them for hundreds of thousands of miles.
BTW, all modern day injectors have built in filter screens to keep out particles big enough to clog the nozzles. But if those get clogged from a failed in-line fuel filter not filtering the incoming gas, then you will have to remove the injectors and have them cleaned, new screens installed and flow tested for uniformity. I just had a set done for The Other Woman and it cost me 17.00 each. The re-build also included the three little o-rings for each injector. Not a bad price.
