Toyota Corolla 2004 Dies but Turns on Again Help?

If your Toyota Corolla is shutting downwards while driving, it'due south a real safety take a chance.  Vehicles are a lot harder to control without power brakes or steering.

Toyota Corolla Shuts Down When Driving: Pinnacle Causes

Direct below is a list of the well-nigh common reasons why your Corolla would randomly die while driving.  It may help you in your diagnosis.  Only, before taking a await at anything, is the check engine light on?  If it is, you lot'll want to start with any trouble lawmaking you become from an OBD2 scanner.

Parts stores can browse information technology for yous if you don't have access to a scanner.  But we don't recommend driving anywhere until your Corolla is fixed, since dying at the wrong time can crusade a collision.

1. Out of Fuel

Your engine needs three things to run properly; air, fuel, and spark.  If your engine is running fine and and then it merely suddenly dies, one of these iii things was abruptly taken away.  It's normally fuel.

The well-nigh common reason that a vehicle shuts off when driving is a lack of fuel.  The most likely cause is an empty fuel tank aided by a fuel gauge that's not as accurate as it looks.  Even if information technology says there is fuel in there, bang on the tank.  If it makes a hollow audio, it's probably empty.

2. Fuel Pump or Filter

Another common reason that your Corolla 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 tin can dice if the fuel pressure is not high enough to properly disintegrate the gasoline properly.

The fuel pump is ofttimes not monitored by the engine's calculator, which means 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 starting time.

If the engine isn't starting, turn the key to the on position and listen really carefully.  Yous should hear a whining noise.  That's the fuel pump priming the fuel system.  If you hear zip, that is a potent indication that the fuel pump is bad.  Since the fuel pump is in the tank, you may desire to get a 2d ready of ears and then yous can be absolutely sure you don't hear it.

If you lot don't hear it at all, you should manually check the fuel pressure at the fuel rails.  If it is not as high as it should be you lot either have a bad fuel pump or fuel filter.

The fuel pump may be going out sporadically.  This would mean that it'll dice on the road, and so burn down support over again fifty-fifty a few seconds later.

3. Battery Cables

Check the battery cables to ensure that they are free of debris and are bolted to the bombardment posts properly.  Follow the black ground cablevision to whatsoever it is continued to.  Make sure that it is secure and there's no corrosion or rust that could exist keeping it from making a solid ground connexion.

iv. Engine to Chassis Ground

The engine needs a strong ground to the chassis in order for your Corolla'due south diverse electrical systems to work.  If that cablevision is corroded, there could be problems such as misfiring, deadening/no starts, or fifty-fifty the engine dying while driving.  This is a common cause of many "gremlins".

5. Bad Alternator

The alternator is responsible for charging the bombardment, and keeping your Corolla running.  If the alternator goes bad, the vehicle will run off of the power supply in the battery (which is at that place mostly for starting the vehicle and as a backup reserve).

Once the battery has been depleted, the ignition system will no longer be able to fire properly. Y'all should see either a battery light or alternator light long earlier the engine dies.  If you didn't see information technology, information technology'southward highly unlikely that the alternator or bombardment is at fault.  If you did see the alarm lite, accept the alternator and battery tested at the parts shop.  Supercede them as needed.

six. 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, fifty-fifty momentarily, the vehicle will not know when to fire the spark plugs and it'll end running.

The mass air flow sensor can besides get bad.  These sensors should trigger a trouble code if they have a problem through.

Conclusion:  Toyota Corolla Dying While Driving

In the absence of a bank check engine light, take a proficient difficult wait at the fuel pump.  If that's not the outcome, we recommend having an experienced mechanic take a look at the problem.  They'll need to tape the telemetry from the OBD2 system when the automobile does it over again.  And then, they'll exist able to determine which office of the vehicle has the problem.  This is a DIY site, nosotros hardly ever throw out the mechanic recommendation.  This can be tough to track
