Mercury Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** and thanks for your question.
Did the water pump take care of the squeal or is it still there? If its still there have you noticed it get the loudest just before it stalls?
OK thanks. The squeal is coming from the camshaft synchronizer. That is also the cause for the stalling. I would replace the synchronizer and the camshaft position sensor. It is possible the P0193 is due to the stalling, but more likely it is caused by the fuel rail pressure sensor/connector, they develop intermittent open circuits between the connector and the sensor. I usually replace the sensor and splice in a pigtail connector. Do all the above and these concerns should be resolved for good.
