Can a asd relay cause Chrysler cirrus to stop running during operation?

While it's *possible*, it's highly unlikely that a failing ASD (Automatic Shut Down) relay would directly cause a Chrysler Cirrus to suddenly stop running during operation. The ASD relay's primary function is to control the fuel pump and other ignition-related circuits. If it fails, the engine should *not* start in the first place.

If your Cirrus is stopping unexpectedly while running, the ASD relay is a *very low probability* culprit. More likely causes include:

* Fuel pump problems: A failing fuel pump, clogged fuel filter, or issues in the fuel delivery system are much more common causes of a car stalling.

* Crankshaft Position Sensor (CKP): A faulty CKP sensor prevents the engine from receiving the timing signals needed to continue running.

* Mass Airflow Sensor (MAF): A malfunctioning MAF sensor provides incorrect air/fuel mixture data, leading to stalling.

* Ignition system issues: Problems with the ignition coil, spark plugs, or wiring can cause the engine to die.

* Alternator problems: A failing alternator can cause a sudden power loss, leading to a stall.

* Computer (PCM) problems: The Powertrain Control Module can malfunction and cause various drivability issues, including stalling.

To diagnose the issue: You should have a mechanic or use an OBD-II code reader to check for diagnostic trouble codes (DTCs). These codes will point to the most likely source of the problem. Simply replacing the ASD relay without proper diagnosis is unlikely to solve the issue and may waste time and money.
