Hello. This may be a faulty starter relay. The starter relay is a small unit usually in the fuse box that directs power to the starter from the battery. When this fails, it may cause a clicking sound and will not allow the starter to engage the flywheel when you turn the key. There is also a starter solenoid on the starter that has internal electrical contacts that transmit electricity to the starter. I would have a professional, like one from YourMechanic, come to your car’s location to diagnose the starting problem and move forward with repairs.

You could have a junk battery and starter. Try unhooking the battery and jumping the Tahoe with the jumper cables hooked to the terminals. If it starts its the battery. If it makes a tick sound every time you try starting it the starter is the problem.
If you hear rapid clicking…
Perhaps your battery`s dead, or your alternator, which charges the battery, isn`t working correctly. If the source of the clicking is electrical, the starter (a small motor energized by the battery that gets the engine running) doesn`t have enough juice to stay powered.
The Battery is Dead
A dead battery is one of the most common causes of a no start. A low or dead battery doesn`t have enough power to turn the starter motor and will result in a rapid, repeated clicking noise when you turn the key. Leaving your lights on overnight can quickly kill your battery.
The most common reasons a Chevrolet Tahoe won`t start are a dead battery, an alternator problem, or failed starter.
Damaged CV joint: The most common cause of a clicking or popping sound from the wheels is a broken CV joint. The CV joints, which stand for Constant Velocity, are essentially the wrists of your vehicle`s steering system.
Usually a rapid clicking noise is a good indication that your starter motor isn`t getting enough electrical current to engage – basically your solenoid is trying to engage but can`t make the connection.
Why won`t my car start but the battery is good? If your car won`t start but the battery is good, the most common cause is a faulty starter – though it could also be to do with your fuel. You may have insufficient fuel to get the car going.
If your starter relay has gone bad, the electrical signal will never make it from the battery to the starter motor. As a result, your engine won`t turn over – no matter how many times you turn the key. A faulty relay often produces an audible clicking sound when you turn your car.
One common culprit for this problem is the crankshaft position sensor, which measures the position and speed of the crankshaft. The computer uses the information from this sensor to know when to fire the spark plugs. If the sensor isn`t working, the spark plugs won`t fire, keeping the engine from starting.
The outer joints pivot, allowing the front wheels to turn. When outer CV joints become worn, they can make a clicking, popping, or snapping sound, especially when the vehicle is cornering and accelerating. Another reason a car can make a popping noise when turning is because of a damaged tie rod.
Escaping gases: Scientists explain that synovial fluid present in your joints acts as a lubricant. The fluid contains the gases oxygen, nitrogen, and carbon dioxide. When you pop or crack a joint, you stretch the joint capsule. Gas is rapidly released, which forms bubbles.
Worn wheel bearings can make all kinds of noises, from snapping, grinding, and humming to the clicking and popping sounds under debate. Symptoms of worn wheel bearings include uneven tyre wear, wheel vibrations, and oddly performing brakes.
The starter relay makes a clicking sound, but the engine does not rotate, which indicates that the starter motor is not receiving enough current from the relay. This may also be a sign of low or exhausted battery power. Only when it transmits enough current to the starter, the relay starts to work.
If you hear a grinding noise when you turn the key or press the start button, you likely have a starter that needs replacement. One of the curiosities about a bad starter is that it can still start the engine.
Trouble Starting or Frequent Stalling
As previously mentioned, trouble starting your engine might mean that your alternator is failing to charge the battery. This means that when you turn the key in the ignition, all you`ll hear is a clicking sound instead of the purr of your engine.
If you`ve replaced your battery but the engine still won`t start, it could actually be an engine problem. A seized engine won`t turn over, and that often resembles a bad starter or dead battery. If you suspect that your problem stems from an engine issue, it could take hours to diagnose and repair.
The short answer is: Yes, it can. It could also drain the battery even faster if you repeatedly try to start your car with a faulty starter.
Car suddenly stalls while operating: One of the most common symptoms of a failed ignition relay is a car that suddenly stalls while operating. If the ignition relay shorts, burns out, or otherwise fails while the engine is operating it will cut off power to the fuel pump and ignition system.
The crankshaft position sensor monitors the position and speed of the crankshaft and other parameters that play an important role when starting the engine. If the crankshaft position sensor is having a problem, the vehicle may have intermittent starting issues or not start at all.
The MAF can become clogged with excessive carbon build-up from the combustion cycle, or sometimes by road grime. If it is too dirty, it will be unable to correctly measure the air fuel ratio, and cause your car to not start or exhibit other unusual symptoms.
With a cranking system, symptoms are divided into one of three possible troubleshooting categories: Click — No-Crank (solenoid clicks but starter doesn`t crank) No-Click — No-Crank (solenoid doesn`t click/starter doesn`t crank) Slow Crank (starter cranks, but engine RPM slow to start vehicle)
A worn outer CV joint will produce loud clicking noises when you turn sharply. Usually, this noise will increase with acceleration. A worn inner CV joint can cause loud clunking noises when switching between drive and reverse.
