I have a 2014 Lincoln MKZ that I have owned for almost 3 years. Until recently I have not had any major issues with the car. Recently the car will start to sputter then randomly die. The check engine light never kicks on. The dealership has replaced the high pressure fuel pump, the fuel pressure sensor at the fuel rail, the fuel pump drive module and the body throttle. Nothing has worked. Sometimes the car will not start, and the start button will flash. When this happens, I am unable to do anything. The dashboard lights will stay lit.
Another dealership has said that without the engine light on, it's nearly impossible to diagnose the issue. Has anyone else had this issue? Any suggestions?
