Why Does My Chevy Tahoe Stall Then After 5 Minutes Start Again
If your Chevy Tahoe is shutting downwardly while driving, information technology'southward a real safety hazard. Vehicles are a lot harder to control without power brakes or steering.
Chevy Tahoe Shuts Down When Driving: Top Causes
Straight below is a list of the well-nigh common reasons why your Tahoe would randomly die while driving. It may help you in your diagnosis. Just, before taking a look at anything, is the check engine lite on? If it is, you'll want to outset with whatever trouble lawmaking you get from an OBD2 scanner.
Parts stores can scan information technology for you lot if you don't accept access to a scanner. But we don't recommend driving anywhere until your Tahoe is fixed, since dying at the wrong fourth dimension tin cause 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 then information technology just of a sudden dies, 1 of these three things was abruptly taken abroad. It'due south usually fuel.
The most common reason that a vehicle shuts off when driving is a lack of fuel. The most probable cause is an empty fuel tank aided by a fuel gauge that'south not every bit accurate every bit information technology looks. Even if it says there is fuel in in that location, bang on the tank. If information technology makes a hollow sound, information technology's probably empty.
2. Fuel Pump or Filter
Another common reason that your Tahoe 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 enough to properly atomize the gasoline properly.
The fuel pump is frequently not monitored past the engine's computer, which means information technology doesn't activate the bank 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 key to the on position and listen really carefully. You should hear a whining noise. That's the fuel pump priming the fuel system. If you hear naught, that is a strong indication that the fuel pump is bad. Since the fuel pump is in the tank, you may want to get a second fix of ears so you can be absolutely certain you don't hear information technology.
If you don't hear information technology at all, yous should manually check the fuel pressure at the fuel rails. If it is non equally high as it should exist you either have a bad fuel pump or fuel filter.
The fuel pump may be going out sporadically. This would mean that information technology'll die on the road, and so burn down support again fifty-fifty a few seconds afterward.
three. 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 cable to whatever information technology is continued to. Make sure that information technology is secure and there's no corrosion or rust that could be keeping it from making a solid basis connection.
4. Engine to Chassis Ground
The engine needs a stiff ground to the chassis in gild for your Tahoe'due south various electric systems to work. If that cable is corroded, at that place could be problems such as misfiring, slow/no starts, or even the engine dying while driving. This is a common cause of many "gremlins".
5. Bad Alternator
The alternator is responsible for charging the battery, and keeping your Tahoe running. If the alternator goes bad, the vehicle volition run off of the ability supply in the battery (which is there mostly for starting the vehicle and as a backup reserve).
In one case the battery has been depleted, the ignition system will no longer be able to burn properly. Y'all should come across either a bombardment light or alternator light long earlier the engine dies. If you didn't see information technology, it's highly unlikely that the alternator or battery is at fault. If yous did see the warning light, have the alternator and battery tested at the parts shop. Supervene upon 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 terminate reporting this information, fifty-fifty momentarily, the vehicle will not know when to fire the spark plugs and it'll end running.
The mass air period sensor can also get bad. These sensors should trigger a problem code if they take a trouble through.
Conclusion: Chevy Tahoe Dying While Driving
In the absence of a cheque engine low-cal, have a good hard look at the fuel pump. If that's not the upshot, we recommend having an experienced mechanic take a look at the problem. They'll demand to tape the telemetry from the OBD2 organisation when the car does it again. And then, they'll be able to decide which part of the vehicle has the problem. This is a DIY site, we hardly always throw out the mechanic recommendation. This can be tough to runway
If there's annihilation that you would similar to add that could assistance the adjacent person with their Tahoe, delight leave a annotate below.
