When your car won’t start and you’re left with a clicking noise or complete silence when you turn the key, the starter motor is often the first place to look. At Z Auto Service in Englewood, CO, our ASE-certified technicians have been diagnosing and replacing starter motors for over 30 years, and we always confirm the starter is the actual problem before recommending a replacement.
A no-start condition can come from several components, not just the starter. We test the battery, alternator, and starter circuit before recommending any work, so you’re not paying to replace a starter when a weak battery or a faulty connection is the real cause.
How the Starter Motor Works
The starter is a powerful electric motor that pulls 150 to 300 amps from the battery to crank the engine’s flywheel and initiate the combustion process. When you turn the key or press the start button, the ignition switch sends a signal to the starter solenoid, which engages the starter gear with the flywheel and powers the motor. When any part of this starting system fails, the solenoid, the motor itself, the starter circuit, or the electrical connections, the engine won’t crank.
In Colorado’s climate, starters face additional demands. Cold starts at Englewood’s elevation put more strain on the starting system than at sea level. The engine requires more cranking effort in cold temperatures, and a starter that’s beginning to wear may reveal its problems more quickly here than it would in a warmer, lower-elevation climate.
Signs of a Failing Starter
Starters typically last 100,000 to 150,000 miles, but they don’t always fail without warning. Common signs include:
- A single click when you turn the key — often indicates a solenoid issue or insufficient power reaching the starter
- Rapid clicking — usually points to a battery or cable problem rather than the starter itself
- Slow or labored cranking — the engine turns over but struggles, which can indicate a weak starter or a weak battery
- Grinding noises during cranking — suggests the starter gear isn’t engaging the flywheel correctly
- Intermittent no-starts — the car starts fine sometimes and refuses other times, often caused by a heat-soaked or failing starter motor
- A burning smell — can indicate an internal short in the starter motor
- Dashboard lights on but no crank — the battery has power but isn’t getting it to the starter properly
Our Starter Replacement Process
At Z Auto Service, we follow a thorough diagnostic process before any replacement is performed:
- Battery and charging system test — we confirm the battery has adequate charge and the alternator is functioning properly before concluding the starter is at fault
- Starter circuit testing — we check the electrical connections, wiring, and ignition switch that feed power to the starter
- Starter motor assessment — we test the starter motor itself to confirm it’s failing and not a peripheral component
- Written estimate — before any work begins, we provide a written estimate so you know the real cost upfront with no surprise charges
- Quality replacement — we install high-quality replacement starters that meet or exceed original specifications, tested for proper function before installation
- Post-installation verification — we verify the starting system is functioning correctly before returning your vehicle
Most starter replacements take one to three hours depending on the vehicle and the starter’s location in the engine bay.

Frequently Asked Questions
How do I know if my starter is failing or if it’s the battery?
The symptoms can look similar, but there are clues. Rapid clicking usually points to the battery or cables. The starter is trying to engage but there isn’t enough power. A single click or grinding noise is more likely to be the starter solenoid or starter gear. Slow cranking could be either. The most reliable way to know is a proper test of the battery, alternator, and starter circuit, which is always our first step before recommending a replacement.
Can I damage my car by continuing to try to start it if the starter is failing?
Repeated start attempts with a failing starter can put additional strain on the battery and electrical system, and in some cases cause the starter to overheat. If your car isn’t starting, it’s better to call us than to keep trying.
How long does starter replacement take at Z Auto Service?
Most starter replacements take one to three hours depending on the vehicle and where the starter is located in the engine bay. We’ll give you an accurate time estimate after our diagnostic inspection.
Do you provide a warranty on starter replacement work?
We stand behind the quality of our work and the parts we install. Ask our service team about the coverage that applies to your specific repair when you bring your vehicle in.
Does Colorado’s altitude or cold weather affect my starter?
Yes. Cold temperatures require more cranking effort from the starter, and combined with Colorado’s elevation, a starter that’s beginning to wear may show symptoms here before it would in a warmer, lower-altitude climate. If you’re noticing slow or inconsistent cranking during cold Englewood mornings, it’s worth having the starting system tested before a failure leaves you stranded.
