Mercury Capri won't restart after engine warms, possible fuel pressure issue on Mercury Capri

Some Mercury Capri owners report experiencing difficulties restarting their vehicles after the engine warms up, which may be linked to issues with the fuel system, such as a faulty fuel pump or fuel pressure regulator. Additionally, problems with the ignition system, including a malfunctioning ignition switch or low voltage at the coil, can contribute to these restarting challenges. Owners also note that following a proper warm start procedure—like pumping the bulb and maintaining the throttle at idle—can aid in restarting the engine smoothly. Furthermore, some find that paying attention to the throttle position while cranking can help diagnose issues like flooding. It is recommended for owners facing these issues to consult a qualified mechanic to thoroughly check the fuel and ignition systems and ensure proper warm start procedures are followed.
