OK, picked up the truck from the shop and asked them how they came up with the diagnosis that all the injectors are bad.
The service writer (complete beeoytch, BTW) said they hooked up their scan tool and ran a buzz test, and all the injectors were quiet, except for 1, and the tech had to get his ear really close to the engine to hear that one, so it was "marginal".
No comment from her on the fact that the oil is less than 500 miles old. She said they won't use reman injectors because they got tired of having to warranty them.
I have a hand held scan tool and did a buzz test before I brought the truck to them, and it ran through the test completely and said "system passed". I heard all the injectors rattling. Now, I get it home and it will run the test, but I can hear 1 injector (quite loud, too, from inside the cab) and then the next one a little fainter for about half as long, then nothing. The test counts down, then says "system indicates test still running, continue? Yes/No). I know it ran and completed the test before.
The "test still running" is the same result when I run any other test, but I saw it and heard it for sure on the injector buzz test. Hell, I can hear the first one buzz clear as day.
What are the chances the module is bad?
