I have a trouble code I cant figure out P0148 fuel delivery error. I have recently installed the air dog fuel transfer pump. But I reconected the factory pump and it still sets the code. Can any one help.

 

Do you have a programmer on the truck? Was it low on fuel? Did you run it outta fuel? Any fuel on the engine block around the injection lines?

How does the truck idle? Does in run rough or miss?

 

I have also just replaced the fuel injectors and was wondering if the fuel cross over tubes could be leaking and causing the code but if they were leaking I thought it would be hard to start. There are no symptoms just the code. I have cleared it repeatedly trying different things. but it still sets the code.

 

The crossover tubes could cause this as well, but as you said it should hard start unless it is a minute amount

 

Does anyone know where I can find a mechanical fuel pressure test kit for this 2006 5.9L Cummins?
