A GROUND WIRE OR ELECTRICAL HASSLE

Does your Subaru Legacy shuts off while driving? Don’t forget to take a look at your electrical system, if it’s a ground wire, for example, which can trigger a short circuit, or a totally damaged electrical circuit that can no longer carry electricity. This is one of the most difficult causes to detect… We advise that you try to discover a “burnt” part for the ground wire, which would show that an electric arc has formed between a cable and the bodywork, however you will surely have to contact a professional to resolve this problem.

IDLE ACTUATOR

The intent of this part is to control the engine idle speed of your Subaru Legacy. If your Subaru Legacy engine unit stops unexpectedly when you’re at a standstill, such as at a red light, check the level of wear on your actuator.

THE FUEL PUMP

One of the most obvious motives, without fuel, the engine stops running. Sometimes, over the years, the fuel pump filter can become clogged or the fuel pump is weak and no longer pumping. Either technique, your Subaru Legacy could stop while driving.

FUEL INJECTION SYSTEM

Same reflection as discovered before, however, in this scenario it is the last phase of the fuel intake into the engine. Seized injectors, a defective injection pump or sensor and your Subaru Legacy can go out of service or completely disable your fuel injection. An injection problem will usually appear when the fuel injection is hot.

NEIMAN ISSUE

A neiman, principally concerning its ignition switch, will occasionally trigger you trouble and trigger your Subaru Legacy to stop while driving. This component, which is necessary for starting your motor vehicle, as well serves as an anti-theft protection, which will prevent your Subaru Legacy from running normally if it fails.

IGNITION COILS (PETROL ENGINE UNIT ONLY)

The penultimate main cause an Subaru Legacy stops while driving is the ignition coil. This origin is just relevant for petrol cars since the engine runs by explosion and not by compression. In case your coils are too worn out, they will no longer spark. Look on that side.

BATTERY / ALTERNATOR

Finally, it is as well possible to be the victim of a tired battery or a damaged alternator. In both situations, the lack of energy stored inside the battery will prevent your Subaru Legacy from running as it will no longer have the ability to power the main parts of your engine unit.
