What Would Cause a 2007 Hyundai Accent to Lose Power Then Start Running Again

If your Hyundai Emphasis is shutting downwards while driving, it's a real condom hazard.  Vehicles are a lot harder to control without power brakes or steering.

Hyundai Emphasis Shuts Down When Driving: Superlative Causes

Straight beneath is a listing of the almost common reasons why your Accent would randomly die while driving.  It may help you in your diagnosis.  But, before taking a look at annihilation, is the check engine low-cal on?  If it is, you'll want to start with whatsoever trouble code you get from an OBD2 scanner.

Parts stores tin can scan it for you if you don't take admission to a scanner.  But we don't recommend driving anywhere until your Accent is stock-still, since dying at the wrong time can cause a standoff.

1. Out of Fuel

Your engine needs iii things to run properly; air, fuel, and spark.  If your engine is running fine then it merely of a sudden dies, 1 of these three things was abruptly taken away.  It'due south usually fuel.

The nearly mutual reason that a vehicle shuts off when driving is a lack of fuel.  The most likely crusade is an empty fuel tank aided by a fuel gauge that's not equally accurate as it looks.  Even if it says there is fuel in in that location, bang on the tank.  If information technology makes a hollow sound, it's probably empty.

2. Fuel Pump or Filter

Another common reason that your Accent may be starving for fuel is a bad fuel pump.  The fuel pump is responsible for sending highly pressurized fuel to the fuel rails.  The engine can die if the fuel pressure is not high plenty to properly atomize the gasoline properly.

The fuel pump is often non monitored by the engine's computer, which ways it doesn't activate the check engine light when you are trying to figure out why the vehicle it is randomly dying.  This is the best place to start.

If the engine isn't starting, turn the central to the on position and listen actually carefully.  You should hear a whining racket.  That'southward the fuel pump priming the fuel system.  If you hear cipher, that is a strong indication that the fuel pump is bad.  Since the fuel pump is in the tank, yous may want to become a 2nd set up of ears so you can be absolutely sure you don't hear information technology.

If you don't hear information technology at all, y'all should manually check the fuel pressure at the fuel runway.  If it is not every bit loftier equally it should exist yous either have a bad fuel pump or fuel filter.

The fuel pump may be going out sporadically.  This would mean that it'll die on the route, so fire back up over again even a few seconds afterwards.

three. Battery Cables

Check the battery cables to ensure that they are free of debris and are bolted to the battery posts properly.  Follow the black ground cable to whatever it is connected to.  Make sure that it is secure and there's no corrosion or rust that could be keeping it from making a solid ground connectedness.

4. Engine to Chassis Ground

The engine needs a strong ground to the chassis in order for your Accent's diverse electrical systems to work.  If that cablevision is corroded, at that place could be problems such every bit misfiring, ho-hum/no starts, or even the engine dying while driving.  This is a common crusade of many "gremlins".

5. Bad Alternator

The alternator is responsible for charging the battery, and keeping your Emphasis running.  If the alternator goes bad, the vehicle volition run off of the power supply in the battery (which is there mostly for starting the vehicle and as a backup reserve).

Once the bombardment has been depleted, the ignition arrangement will no longer be able to fire properly. You lot should meet either a battery light or alternator light long before the engine dies.  If y'all didn't encounter it, information technology's highly unlikely that the alternator or battery is at fault.  If you did see the warning calorie-free, accept the alternator and battery tested at the parts store.  Supplant them as needed.

vi. Issue With Sensors

The crankshaft and camshaft sensors are responsible for telling the engine where the crank and cam are located in their 360° revolutions.  If they stop reporting this data, even momentarily, the vehicle volition not know when to burn down the spark plugs and it'll stop running.

The mass air flow sensor tin can also go bad.  These sensors should trigger a trouble lawmaking if they have a trouble through.

Decision:  Hyundai Accent Dying While Driving

In the absence of a bank check engine lite, take a skilful hard look at the fuel pump.  If that's not the consequence, we recommend having an experienced mechanic take a look at the problem.  They'll need to record the telemetry from the OBD2 organisation when the machine does information technology again.  And then, they'll be able to make up one's mind which office of the vehicle has the problem.  This is a DIY site, we hardly always throw out the mechanic recommendation.  This tin exist tough to track
