New injectors bad?

[Demian1970]

Hello fellow Powerstroke fans. Need some advice.
I replaced my injectors back in April ('11) with a reman set. All 8. Truck ran OK, but come to find out I had cylinder wall damage on #8. Low compression.
Removed the head, found the wall damaged, sent out the block to have it sleeved and punched out .30, blah, blah, blah, basically new engine at this point.
Still seems to be running rough, especially on cold start up. (glow plugs and glow plug relay are new) Brought it into a diesel specialty shop here in Atlanta for a diagnosis, and they informed me that ALL my injectors are bad. One was "on the threshold", but they are all bad. Also said I have an aftermarket fuel filter and that is a no-no, and I need an oil change. Now, mind you, the engine has less than 500 miles on it since being rebuilt, and I've replaced the oil filter twice since then, anyway.
I have a scan tool that will do an injector buzz test, and it says that the system passes. (won't seem to run any other tests, but it lists them in the menu)
Does that seem possible?

I would say anything is possible. I would do some testing and go from there.

where did you buy the injectors?

[Demian1970]

Injectors came from Diesel Care and Performance in TN.

At least they didn't come from Peninsular Diesel, the scourge of Ebay.
The shop that said they were all bad,, didn't they say how they came to that conclusion?

its not bill hewitts shop is it? isnt he in atl, or just outside it?

normally all injectors dont go bad at once, unless you like run metal shavings or something through them lol. all 8 can be worn out for sure, i would like to know how they came to this conclusion as well.

I'd like to know how they came up with that diagnosis, as well.I dropped off my truck before going out of town for Christmas.
They said they "hooked up their diagnostic scantool" to get the codes and ran some test and that's what they came up with.
I don't have a diesel specific scantool, but it will get codes from it, and the only recurring code I kept getting was one for the intake air heater shorted.
The shop is Turbo Diesel and Electric systems in Woodstock. There's also one in Forest Park.

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?

[Demian1970]

Anyone? Bueller? Bueller?

Just my .02 cents but if the module is cheaper than replacing all 8 injectors I would try that first. There should be a way to check it. I have had nothing but bad luck anytime I use remain parts unless they come from Ford or Motorcraft. l know we all hate to do this but sometimes its better to go to the stealership...
