A Guide to Replacing the Starter Motor on Your 1987-1992 Buick Skylark
Solve your Skylark's no-start problems by understanding how to choose the right replacement starter.
- Always test the battery and check cable connections before deciding to replace the starter.
- If you have a 2.3L Quad 4 engine, be aware that a cracked flexplate can make a noise similar to a bad starter.
- The job is DIY-friendly for those with basic tools and can be completed in 1-2 hours.
- A quality new aftermarket starter from a brand like ACDelco is a reliable and readily available option.
Is Your Skylark's Starter Failing?
A bad starter is a common reason a car won't start. For the 1987-1992 Buick Skylark, the signs are usually clear. If you turn the key and hear a single, loud click, a rapid series of clicks, or a grinding noise, the starter is a likely suspect. A completely dead starter might make no sound at all, even though your dashboard lights and radio work fine.
Check These First!
Starting problems are not always the starter's fault. Before spending money, always check these simple things:
- Battery and Cables: A weak or dead battery is the most common cause of a no-start condition. Make sure your battery is fully charged and that the terminals are clean and tight. Corroded or loose cables can prevent the starter from getting enough power.
- Ignition and Safety Switches: On some GM vehicles of this era, issues with the ignition switch or the neutral safety switch (which prevents starting in gear) can mimic a bad starter.
- Vehicle Anti-Theft System (VATS): Some GM cars use a key with a small black resistor pellet. If the system fails to read this resistor, it will prevent the car from cranking to deter theft. This can easily be mistaken for a failed starter.
Known Issues for 1987-1992 Skylarks
While generally reliable, there are a couple of specific issues to be aware of on these cars:
- Starter/Flywheel Clash TSB: General Motors issued a Technical Service Bulletin (TSB #86-6-26A) for some 1986 models regarding a "clash or mill" noise between the starter and flywheel gears. This issue may also affect early 1987 models. It can cause grinding noises and damage to the flywheel teeth.
- Cracked Flexplate (Quad 4 Engine): On models with the 2.3L Quad 4 engine, a loud knocking or grinding noise can be caused by a cracked flexplate. This is often misdiagnosed as a bad starter or major engine failure. It is critical to inspect the flexplate for cracks when replacing the starter on these engines.
Choosing the Right Aftermarket Starter
You don't need to go to a dealer for a quality starter. Aftermarket brands offer good value, but it's important to understand what you're buying. For your Skylark, you'll find both new and remanufactured options.
- New Aftermarket (e.g., ACDelco Gold/Professional): These starters are made with 100% new components. ACDelco is GM's own parts brand, and their aftermarket lines are built to meet specific performance standards. While many are manufactured in China, they are computer-tested and designed for proper fit and function. This is often a reliable choice with a good warranty.
- Remanufactured (e.g., MPA): Remanufactured starters are original units that have been taken apart, cleaned, and rebuilt with new components to replace worn parts. The quality can vary, but reputable brands follow strict testing processes. This can be a cost-effective option, but it's important to choose a brand that offers a good warranty.
When you remove your old starter, take a moment to inspect the teeth on the engine's flexplate through the mounting hole. If you see chipped, broken, or heavily worn teeth, the flexplate may need to be replaced to prevent damage to your new starter.

Frequently Asked Questions
Can I replace the starter myself?
Yes, for a person with some mechanical experience, this is a manageable job. It typically takes 1-2 hours. You will need a good jack and jack stands, a socket set, and possibly some extensions to reach the bolts. The starter is located on the front of the engine where it meets the transmission and is accessed from underneath the car.
Does a single click when I turn the key always mean a bad starter?
Not always, but it's a classic symptom. The click you hear is the starter's solenoid trying to engage. A single click often means the solenoid is working, but the starter motor itself has failed or there isn't enough battery power to turn it. Always test the battery first.
What's the difference between a new and a remanufactured starter?
A new starter is built from all-new components. A remanufactured starter is an original equipment (OEM) core that has been disassembled, inspected, and rebuilt with replacement parts for anything that was worn or failed. A quality remanufactured part can be just as reliable as a new one, and sometimes uses a more durable original housing.
Do I need to use shims when installing the new starter?
Maybe. Some GM vehicles of this era require thin metal shims between the starter and the engine block to ensure the gears mesh correctly. If your old starter had shims, you should reinstall them with the new starter in the same configuration. If you experience a grinding noise after installation, you may need to add or adjust the shims.
