99 Super duty

Make the dealership eat the cost and labor for the supposed bad injector and if module don't fix it, make them eat those costs too. They r just throwing parts at it in hopes of fixing the problem.

The dodge dealership tried that with me when my Tck started acting an ass. I knew the issue was in the tank and told them that, but they decided to do their own diagnosis, which is fine if they would have stayed in the tank area. They chose to tell me the cp3 pump was weak and I had a clogged rail. I called bs, told them to go to the tank. There they said the lift pump was bad. I told them to clean and test the pump. They'd test the pump and tell me it's low on output psi by 150psi. I ask him if it was tested clean or as it sits, and he says as it sits. I go up there n talk to both the mech, service writer and manager all at the same time so there were no miscommunications after I left.
After cleaning the pump, wow, it's a miracle, the pump worked with in normal parameters, and then they tell me me my inlet line at the filter housing is bad and want to sell it and install it for me. I ask why they think I need I need a new line, and it was bc the plastic .25c clip that holds the line onto the inlet nipple was broke and half was missing and u can get just the clip and it was leaking fuel. I ask they are sure it is the line since it wasn't leaking when I brought it to them. We'll come to find out, it was even the line after all, it was the o ring at the filter housing cap that they must have cut during their diagnosis and didn't find this out till after I get home. Thank goodness I still had the other o ring from when I changed the filter at the beginning of the ordeal.

Moral of my story. The dealerships don't have technicians as they claim, they have parts changers. Hold their feet to the fire and tell the dealership if it doesn't fix the issue, they will eat the cost of all the work they'd have been doing to just throw parts at it
