Had all injectors tested some rebuilt by a pro shop. Truck will only start and run if you crack number 1 injector. Weirdest thing I have ever seen. Tighten the line truck dies. It runs very rough and sporadic and pushing on the accelerator does nothing at all. I have torn it all back down and reinstalled everything with exact same results Also replaced all of the connector tubes too. HELP PLEASE!!

 

I would try to get that on a scan tool, but for the time being potentially an issue with FCA??

 

I wouldn't run it with the line cracked- the psi is ridiculously high on these motors - about 20k+ psi- although the injectors were rebuilt there is a good chance that an injector is still failing. Remaned injectors are not the same as new. I would check the balance rates on them and see how they look- +/- 4% is about max tolerance you want
