Fuel injector of the cylinder 6 code

In my case this code meant I had to replace the injector. Code kept coming back and at one point injector completely froze. Replaced with good used one and do far so good, if next one goes kabum will replace them all.

You say you had injectors replaced though, with new ones? May be a faulty injector, probably has an electrical issue.

 

Have the guy fix your truck. Sounds like you either got bad part or the guy does not know what he is doing.

 

First whoever installed the injectors needs to put in the calibration codes in the ecm, after this the injector has to be adjusted properly and then if code still pops up you have a bad injector.
