replaced cracked fuel line, truck started and ran for several minutes then it shut down on it's own code shows all injectors failed and check engine light still comes on
Engine: CAT 3126
Hi. Thanks for using JA! I will try and help you out.Are you saying you have codes for all six injectors and the engine will not start?
Yes. Mechanic was going valve cover and check for oil leaks at injectors.
I see. Thanks for the information. I'm sure your injectors are fine. Your problem is the engine ECM. I have seen this many, many times over the years. Whenever an ECM has codes for all of the injectors, this means the injector driver module inside of the ECM has failed. When this happens, the engine will not start or will start but only run for a very short time. Unfortunately, the ECM will have to be replaced, they cannot be repaired. Sorry, I wish I had better news.Please reply back if you need more help or have more questions.
