A Comprehensive Guide to the Starter for the 2006-2014 GMC Sierra 1500
If your Sierra 1500 clicks but won't start, or won't crank at all, this guide will help you find the right replacement starter.
- A single 'click' with no crank is the classic sign of a failed starter, but always test your battery first.
- A GM Technical Service Bulletin (TSB) addresses a known issue where starters can fail to crank in very cold weather; an updated part is available.
- For a balance of quality and price, choose a new starter from a premium aftermarket brand like Bosch or Denso.
- Replacement is a manageable DIY job for those with some mechanical experience, typically taking 1-2 hours.
Is Your Sierra's Starter Failing? Common Symptoms
A starter motor rarely fails without warning. For 2006-2014 GMC Sierra 1500 owners, the signs are usually clear. Always check that your battery is fully charged and the terminals are clean before blaming the starter, as a weak battery can cause similar symptoms.
- Single Loud Click: The most common sign is a single, loud "click" when you turn the key. 🎬 Watch: What a single click sounds like and how to fix it. This means the starter's solenoid is working, but the motor itself isn't turning the engine over.
- Rapid Clicking Noise: A fast clicking sound can also point to a bad starter that isn't getting enough power to engage.
- No Sound at All: You turn the key, the dash lights come on, but there is no crank and no clicking sound.
- Slow or Labored Cranking: The engine turns over very slowly, like the battery is dying, even when it's fully charged. This suggests the starter motor is worn out and struggling.
- Intermittent Starting: The truck may start perfectly one day but refuse to crank the next. This often gets worse over time.
- Grinding Noise: A harsh grinding sound during or after the engine starts indicates the starter gear is not meshing correctly with the flywheel, which can cause serious damage if ignored.
Known Issue: Cold Weather No-Start
General Motors issued a Technical Service Bulletin (TSB) for a condition where these trucks may not crank in very cold temperatures (around 0°F / -18°C). The symptom is a "click, no-crank" situation with no error codes. If the battery is confirmed to be good, the TSB recommends replacing the starter with an updated part (GM P/N 12655055). Sometimes, using a jump-starter provides just enough extra voltage to make the failing starter work, misleadingly pointing to a battery problem.
Choosing the Right Aftermarket Starter
When replacing your starter, you have a choice between OEM and various aftermarket brands. While an OEM part offers a guaranteed fit and quality, it comes at a premium price, often two to three times higher than aftermarket options. For a vehicle in this age range, a quality aftermarket starter provides a great balance of performance and value. Aftermarket brands can be grouped into tiers based on quality and reputation.
Brand Quality Tiers
Tier 1: Premium Aftermarket (Bosch, Denso)
These companies are often the original equipment manufacturers for many car brands. Choosing a new starter from Bosch or Denso is the closest you can get to OEM quality, sometimes even exceeding it. They are known for high-grade materials and rigorous testing, making them a top-tier choice for reliability.
Tier 2: Reliable Value (Remy, Valeo)
Brands like Remy have a long-standing reputation and receive positive feedback for their new and remanufactured starters. Valeo is another established OEM supplier. These brands offer a solid combination of quality and affordability, making them a dependable choice for most owners.
Tier 3: Economy Aftermarket (BBB Industries, WAI Global)
These brands are widely available and offer the most budget-friendly prices. However, quality can be inconsistent. Some users report long life from a BBB starter, while others have experienced early failures with economy brands. WAI Global reviews are particularly mixed. These can be a viable option if budget is the primary concern, but they carry a higher risk of premature failure compared to premium brands.

Is it the Starter or the Wiring?
In some GMT900 trucks, a no-crank condition can be caused by a corroded wiring splice (Splice J308) located in the driver's side door sill. This prevents the Body Control Module (BCM) from sending the 'start' signal to the starter relay. If you're experiencing intermittent no-start issues, checking this wiring could save you from replacing a perfectly good starter.

Is a new or remanufactured starter better?
A new starter from a premium brand like Bosch or Denso is generally the most reliable option. However, a remanufactured starter from a top-tier brand is also an excellent choice, as they are rebuilt to meet or exceed original specifications. The quality of a remanufactured part depends entirely on the rebuilder.
How can I be sure it's not just a dead battery?
If your dashboard lights are bright and don't dim when you turn the key, the battery is likely fine. If trying to jump-start the truck doesn't help, the problem is almost certainly the starter. You can also get your battery tested for free at most auto parts stores.
How difficult is it to replace the starter myself?
For a 2006-2014 Sierra, the job is considered intermediate in difficulty and can be done in 1-2 hours with basic tools. The starter is located on the passenger side of the engine and is held by two bolts. You will need to safely raise the vehicle to get access from underneath. Many DIY videos are available online to guide you.
