INMKZ Posted March 18, 2022 Share Posted March 18, 2022 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?

leftoverture Posted March 18, 2022 Share Posted March 18, 2022 It sounds to me that the dealer you are using is just randomly replacing parts rather than accurately diagnosing. You do not need a code to diagnose an issue like this, you just need the time and patience to properly trace through the systems likely to be involved. I would suggest you find a really good independent mechanic in your area that can properly diagnose the issue. Try to see if you can get some references from your neighbors or coworkers.

drolds1 Posted March 18, 2022 Share Posted March 18, 2022 (edited) Some more details might be helpful, e.g., 2.0l or 3.7l, what diagnostics the dealer has run, how often this happens and under what conditions. Have you been able to demonstrate this to the service techs? It shouldn't be that difficult to diagnose if it happens while they have the car. They can connect the scan tool and freeze data when it happens. Edited March 19, 2022 by drolds1 typo Quote Link to comment Share on other sites More sharing options...
