Crank but won't start

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! If your 2019 Lincoln MKZ is cranking but won’t start, there are a few likely culprits to check. The main suspects here would be fuel delivery or ignition issues. A failing fuel pump or bad spark plugs can all cause this. Another potential culprit could be the battery, particularly if it’s running low on juice—it may crank, but not enough to get the engine fully going. One quick test is to listen for the fuel pump's hum when you turn the key to “on.” No sound? That could be your issue. Otherwise, a diagnostic scan can help pinpoint what’s happening under the hood.
