1991 Gmc S10 problems
The Chevrolet S-10 is a compact pickup truck produced by Chevrolet. It was the first domestically-built compact pickup of the big three American automakers. When it was first introduced as a "quarter-ton pickup" in 1981 for the 1982 model year, the GMC version was known as the S-15 and later renamed the GMC Sonoma. A high-performance version of the latter was released in 1991, called "Syclone." The pickup was also sold by Isuzu as the Hombre from 1996 through 2000, but only in North America. There was also an SUV version, the Chevrolet S-10 Blazer/GMC S-15 Jimmy. An electric version was leased as a fleet vehicle in 1997 and 1998. These models are sometimes internally referred to as the S/T series to denote two and four wheel drive models respectively (similar to the full size Chevrolet C/K trucks) despite all versions being badged with 'S' nomenclature.
In North America, the S-series was replaced by the Chevrolet Colorado, GMC Canyon, and Isuzu i-Series in 2004.
The S-Series ended production in Brazil in 2012, being replaced by the Chevrolet Colorado, but still with the name S-10.

Common 1991 Gmc S10 problems
The GMC S10 1991 is a reliable and sturdy pickup truck, but like any vehicle, it can experience certain problems. Here are some common issues based on complaints from owners of this car:
- Ignition Control Module Failure: Another common problem is ignition control module failure, which can cause the engine to die after a certain period of driving, typically around 12 to 15 minutes. This issue is often resolved by replacing the ignition control module.
- Coolant Temp Sensor Failure: The coolant temp sensor for the computer may also fail, leading to the engine dying when it reaches normal operating temperature. This issue can be diagnosed by checking the coolant temp sensor for the computer and ensuring it is functioning properly.
- MAP Sensor Failure: The MAP sensor can also fail, leading to idle problems and a check engine light. This issue can be diagnosed by checking for vacuum leaks and ensuring the EGR is functioning properly. If there are no codes present, it is possible that the MAP sensor is going bad.
- Idle Problems: Some owners have reported idle problems, where the engine revs to 1200 then back down, and the check engine light comes on. This issue can be caused by a variety of factors, including vacuum leaks, EGR problems, or a faulty IACV.
- Steering Wheel Position Sensor Failure: The steering wheel position sensor can also fail, leading to a service stability message. This issue can be resolved by replacing the sensor, which will cost around $200 to $300.
- Windshield Wiper Motor Component Failure: The windshield wipers on models made between 1990 and 1999 may stop working intermittently due to a defective wiper motor. This issue can be resolved by replacing the wiper motor control board.
- Coolant Leaks or Oil Leaks From Intake Manifold Gaskets: Some owners have reported coolant leaks or oil leaks from intake manifold gaskets, which can be costly to repair. This issue can be resolved by replacing the gaskets, which will cost around $1,000 to have done by a mechanic.
- Restricted Secondary Air Injection Valves: Silverados and Sierras made between 1999 and 2007 are prone to a problem in which the secondary air injection check valves leading to reduced airflow and causing the check engine light to come on. Fixing this problem requires you to replace the check valves.
- 4WD Transfer Case Encoder Motor Position Sensor Failure: 1999-2007 Chevy Silverados and GMC Sierras are also known to experience failed 4WD transfer case encoder motor position sensors or selector switches, which can cause issues with the 4WD system.
- HVAC Temperature or Delivery Mode Door Actuator Failure: 1999-2007 Chevy Silverados and GMC Sierras are also known to experience failed HVAC temperature or delivery mode door actuators, which can cause issues with the heating and cooling system.
- Fuel Level Sensor Failure: 1999-2007 Chevy Silverados and GMC Sierras are also known to experience failed fuel level sensors, which can cause issues with the fuel gauge.
It is important to note that these issues may not affect all GMC S10 1991 models, and some may not experience any of these problems. However, if you are experiencing any of these issues, it is recommended to have your vehicle inspected by a certified mechanic.
