Standard Ignition LX-345 Ignition Control Module

Ignition Control Module for OE-Style Repair

Standard Ignition LX-345 is an external ignition control module built for 12-volt systems and direct-fit service on select GM compact cars. It is engineered for reliable coil control, stable operation in vibration-heavy environments, and consistent starting performance when the original module has failed.

Fits 1987-1991 Chevrolet Cavalier, N/A. Fits 1987-1991 Chevrolet Corsica, N/A. Fits 1987-1991 Pontiac Tempest, N/A, compatible with vehicles equipped with Canada Emissions. Fits 1987-1989 Buick Skyhawk, N/A. Fits 1987-1988 Oldsmobile Firenza, N/A.

Key Features

• External ignition control module for 12-volt applications
• Female connector with 5 connector cavities
• Male blade terminals for secure electrical connection
• Double wire bonds for stronger internal connections and improved durability
• Copper slug heat sinks to help dissipate heat from the module
• High-temperature polymer housing to reduce moisture intrusion and vibration damage
• Responds to weak crankshaft position sensor signals for quicker coil energizing during cold starts
• Durability tested through 500 thermal cycles from -40C to +125C

Detailed Description

Standard Ignition LX-345 is an ignition control module designed to restore proper spark control when the original unit no longer performs as expected. It uses a rugged housing, improved heat management, and reinforced internal connections to handle the electrical and thermal demands of daily driving. This module is a practical choice for Chevrolet Cavalier, Chevrolet Corsica, Pontiac Tempest, Buick Skyhawk, and Oldsmobile Firenza applications listed above, including Pontiac Tempest models with Canada Emissions.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part Can Help Solve

• No-start condition caused by ignition module failure
• Intermittent spark loss or weak ignition output
• Hard starting in cold weather
• Misfire or rough running related to unstable coil triggering
• Heat-related module breakdown from repeated thermal cycling

Installation Notes and Tips

Verify connector style, terminal count, and mounting location before installation. Clean the mounting surface and inspect related ignition wiring, crankshaft position sensor output, and coil condition so the replacement module is not affected by an upstream fault. Confirm vehicle emissions configuration on Pontiac Tempest models before ordering.

Quality Assurance

Standard Ignition manufactures electronic ignition components with in-process quality control from component selection through final assembly.
