A blown fuse in the starter circuit could be the cause of a no-start problem. Broken or corroded wiring – Damaged or dirty wires to the battery or to the starter solenoid (or wires that are loose) can prevent sufficient power from reaching the starter.
In most cars, it will be under the hood, in a large box with a black lid. This is where car fuses and relays are installed. It is also called a fuse box. This box is usually installed on the driver's side of the vehicle.
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.
Faulty Fuse
And if that's faulty or the fusible links are damaged, your car wont start. A damaged or blown fuse can prevent power from reaching the starter relay, which is needed to provide the spark, the ignition, and the power to move your vehicle.

Why won't my car start but I have power? If you attempt to start up your car but the engine won't turn over and the dashboard lights up, then you most likely have an issue with your battery. You could have a damaged or corroded battery terminal, which is stopping the engine from starting up when you fully turn the key.
It may have a shorted winding or a loose wire short that shows up when it is turning. If it is actually a fuse in the fuse-box then your starting circuit may include a relay (usually under the hood) that feeds power to the starter solenoid. If the relay is fused and blowing this fuse then the problem is in the relay.
There's debate on exactly how long fuses last, with some manufacturers claiming fuses can last, 20, 30, even 40 years. However, in the auto industry it's recommended to check or consider replacing fuses after 10.
The average cost for a Starter Relay Replacement is between $66 and $74. Labor costs are estimated between $29 and $37 while parts are priced between $37 and $37.
If you don't hear clicking when you start the engine, the problem may be a dead battery. If you hear clicking, but the engine doesn't crank, the starter might not be getting enough electricity. Using your owner's manual and a voltmeter, you should be able to test functionality.
If your vehicle won't start, it's usually caused by a dying or dead battery, loose or corroded connection cables, a bad alternator or an issue with the starter. It can be hard to determine if you're dealing with a battery or an alternator problem. Here's how to know which one is the culprit.
A car's engine won't start if you jump-start it with a damaged starter motor. Jump-starting just increases the power of the battery. An auto transmission automobile cannot be pushed or towed started. However, a manual transmission car with a broken starter may.
A bad starter can, and will drain your battery if you don't take care of your vehicle regularly. With these tips, however, you can prevent this from happening.
The starter can also cause this to blow. If the starter is failing, especially the starter solenoid, a power surge may be being sent to the fuse and blowing it. You can have your starter bench tested, but they wont test if the starter is powerful enough to actually turn over the engine.
Connected to the battery is the alternator, which works to generate power for your vehicle's electrical components. When you have a brand-new battery but still can't start the car, the alternator might be the issue. Cold and damp climates may increase wear on an alternator, causing it to fail.
It might be a battery or alternator problem.
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. So instead, it rapidly turns on and off and produces a clicking noise!
A brand-new starter can range from $80 to over $350. For a qualified mechanic to replace or rebuild your starter, you can expect to pay between $150 and over $1,100. These estimates vary dramatically depending on the particular issue and the make, model, and year of your vehicle.
The most common reason cars don't start is a dead or faulty battery. Even though most cars run on gasoline, they all require electrical power to function. The starter that cranks your engine to start requires an electrical signal to fire. If something's wrong with your battery, your car engine won't turn over.
If nothing happens when you turn the ignition key to the "Start" position, it means that the starter motor doesn't turn over the engine. Most commonly this could be caused by a low battery; read above How to check the battery.
Car key sensor is not working: If the key is not working at all, it may be due to the drained battery, faulty fob, low car battery, or faulty keyless entry system (if applicable). You can try replacing the fob batteries, diagnosing the fob or towing the vehicle to a service centre to fix the issue.
