Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
The APS is fine.
Yes, brand new. I guess I forgot to list that.
We added the k low pressure after the problem was already there.The thing is we have bypassed everything from the CP3 back to the fuel tank by placing a small fuel tank under the hood the CP3 is pulling directly from. This did not change anything.So the problem is from the CP3 to the injectors. But everything there is brand new. CP3, Fuel control actuator, fuel rail relief valve, injectors and all the rubber hoses. There is nothing else to replace.
05 LLY don't have flow programming?
I have never seen LLY injectors have the flow programming. These injectors were direct from Chevy and had no ID tag programming numbers.
Yes, we took it to the dealer across the street and they done a full update on it. It is actually over there again now because we got a whole new ECM to try because we are out of options.
ECM did not fix the problem. We ended up just leaving the truck with them to see what they come up with.
Dealer could not figure it out either. We ended up tearing the whole system apart this morning and found the rail supply line orifices plugged up solid.
How do I get my money back since no one on here helped us?
