1998 Mercury Tracer Q&A
1998 Mercury Tracer Question: Why the engine shut off when I stop at the light?
It happens all the time specially if I stop suddenly, no Mechanic seems to know what the problem is. - Visitor
It should not be too terrible difficult to diagnose. The engine needs compression, spark and fuel to run. A scan tool attached to the 16 pin diagnostic socket drive the car look at live sensor data. When the engine stalls sensor data can be read to see if the computer sees engine revolutions, air entering the engine, ect.... A car like this I tee into the fuel line tape a pressure gauge to the windscreen and monitor pressure as I drive see if it fails when the car fails. I would look for vacuum leaks as well. When the car stalls I would look for injector pulse (on a professional grade scan tool you can look at injector pulse). - patrick mannion
