Thanks, Eric. I assume mine is within spec. Anyway I found a problem with its connector. One of the terminals was pulled too far back in the connector. I was able to push it forward, so now there's a good connection and the injector sprays nicely. Unfortunately, it doesn't seem to shut off after 8 seconds like I'd expect, so maybe there's something funky with the TTS, or maybe I just didn't wait long enough.
