There are many reasons why your car stops while you drive but then starts again. There could be problems with your fuel tank, ignition, mass air flow sensor or catalytic converter. Do not panic! Most of these problems can easily be fixed by replacing just a few parts. Learn how to fix this very frustrating problem.
Problems with the catalytic converter
If your car stops while you are driving, but restarts after a few seconds it could be time to have its catalytic convert checked. Catalytic convertors are used to reduce the car's emissions. When they malfunction, this could cause many problems with the engine. Here are some warning signs.
Poor compression. A blocked catalytic convert may cause the fuel mixture to be too rich. The car will jerk if this happens. Use a catalytic cleaner to clean your catalytic engine. These products can be costly, so your mechanic might recommend them. To get the best diagnosis and repair possible, take your vehicle to a mechanic.
Problems with your fuel pump
A faulty fuel-pump is one of most common problems for cars. There are many reasons this can happen, including worn fuel pumps and faulty ignition. Check the fuel pump if your car stops while you drive but then starts up again. You can prolong the life expectancy of your fuel pump by changing your fuel filter frequently to avoid fuel pump clogging. You may need to replace the fuel filter if your car suddenly stops driving, but it starts again.
In addition to malfunctioning ignition, the fuel pump can also fail to send the correct amount of fuel to the engine. The fuel pump relay provides fuel to your engine. If this happens, it can make a buzzing sound or whine when you turn the ignition. Sometimes, the relay doesn't deliver the right amount of fuel. If this happens, your car might stall at highway speeds and then start again after restarting. You should be able to recognize signs of a faulty fuel pump relay before your car stops starting. If your car stops starting after you drive it, it may be a problem with the fuel pump relay.
Problems with the ignition system
It can be frustrating to have your car stall. There are many causes. An ignition module problem can cause it to happen while driving. It can stop the engine, or it may be due to a faulty mass air flow sensor. A faulty mass flow sensor can shut the engine down if it detects too much or not enough air. Problems can be intermittent or multi-faceted.
The fuel filter and/or fuel problem can also cause your car's to stop while you drive. If the fuel filter is clogged, it may also be the culprit. A carb cleaner is able to help if the fuel filter is clogged. A new carburetor could be installed if it's not. If these solutions don't work, the ignition system may be the problem. Your mechanic might suggest that you inspect the engine control module and crankshaft position sensor if you aren't sure what is wrong.
Problems with the mass flow sensor
Problems with the mass flow sensor could cause your car to stall while you are driving, but it will start right back up. In this case, the mass air flow sensor is not getting an accurate reading. You can test the mass flow sensor by driving the car without it. The computer will estimate the airflow and might even give better results. The computer will use the guess to calculate the fuel mixture and may even give you a better mix than the actual amount.
If you're experiencing any of these symptoms, it's likely your car's mass air flow sensor is faulty. This sensor measures the airflow into and out of the combustion chamber. If it's not functioning properly, your car's engine may not receive the proper air-fuel mixture and run lean or rich. If you suspect this problem, it's time to get it checked.
FAQ

How To
How to properly diagnose and repair your vehicle
To determine if your car needs repairs, you should first look at the symptoms that your car presents. Follow these steps to properly diagnose your vehicle.
-
Check engine lights. Make sure to check all dashboard indicators like the engine light indicator (oil pressure gauge), the battery indicator (battery light indicator), and the RPM indicator (rpm gauge). If they have been flashing for more days than usual, it could be a sign that something is wrong with the vehicle.
-
Take a look at the treads. Tires that are worn can cause issues with handling and braking. Also, inspect the treads of your wheels. They should be clean, and they should be smooth. To do this, remove the wheels and take them out. A flashlight can be used to check how worn the treads are.
-
You should always monitor the level brake fluid. It is important to keep track of how much brake fluid you have in your car. This ensures that your brakes work properly. Low brake fluid levels can cause brake failure when you apply pressure.
-
You should test the suspension system. The suspension system in vehicles absorbs vibrations and shocks. It provides better control and allows smoother acceleration and deceleration. Your vehicle might feel wobbly, or shake uncontrollably if it has a bad suspension. If you are unsure if your vehicle is suffering from a suspension problem, put weight on the front and rear axles to check the movement.
-
Examine the steering column. The steering columns are what connect the steering knob to the rest. Many accidents can cause damage to steering columns. Replace it if your steering column feels loose or unsteady.
-
Pay close attention to the exhaust tube. The exhaust pipes transport gases from the combustion chamber to outside. If your exhaust pipe leaks or cracks, it will allow harmful fumes into your cabin. Additionally, your tailpipe should be fixed immediately if it is bent.
-
Take a look at the underside of your hood. Take a look underneath the hood to find any strange or unusual items. You could have fluids leaking from the engine. In addition, if you notice an unusual smell coming from your engine compartment, you should contact a professional technician.
-
The air filter should be checked. Your vehicle's air filter collects dust and debris from the outside environment. Vehicles that have a dirty air filter will not run well. Replace your air filter regularly.
-
Check the fan belt. Your vehicle's fanbel connects the engine and transmission. The engine will not turn if the fan belt breaks. It's easy to replace the belt. All you need to replace the belt is a screwdriver with pliers.
-
Verify the radiator hoses. The radiator hose transports water from radiator to engine. It can cause hot liquid to leak onto the engine if it is damaged or cracked. To repair the leaky hose, all you need is a pair if needle-nosepliers.
-
Check the windshield wipers. Windshield wipers use electricity to remove snow and rain. If they stop working, streaks could be left on your glass. The solution is to change the washer fluid.
-
Make sure you check the cables. Your car's electrical system is powered by batteries. When you replace batteries, make sure to disconnect the negative cable first. Failure to do so can damage your alternator.
-
