Standard Ignition LX-325 Ignition Control Module

Ignition Control Module for Distributor Systems

The Standard Ignition LX-325 ignition control module is built for distributor-mounted applications that need stable spark control and dependable cold-start performance. It is used across a wide range of Chevrolet, GMC, Pontiac, Buick, Oldsmobile, Isuzu, Cadillac, and Jeep applications, including Chevrolet S10, GMC S15, and Pontiac Sunbird fitments.

Standard Ignition LX-325 is engineered for 12-volt systems with a bolt-on attachment method, male connectors, and blade terminals for inside-distributor mounting.

Key Features

• Bolt-on ignition control module for inside distributor installation
• 12-volt design with 2 male connectors and male blade terminals
• No coil included
• High-temperature polymer housing helps reduce moisture intrusion and vibration damage
• Copper slug heat sinks improve heat dissipation
• Built to respond to weak crankshaft position sensor signals for quicker coil energizing
• Durability tested through 500 thermal cycles from -40C to +125C

Detailed Description

The LX-325 is a distributor ignition control module designed for vehicles that rely on internal distributor mounting and blade-terminal electrical connections. It is a direct-fit style replacement for many older GM and Jeep applications, including Chevrolet S10, GMC S15, Pontiac Sunbird, Buick Skylark, and Oldsmobile Cutlass Ciera models. This part number, LX-325, is also cross-referenced to AMS Automotive 7052 for the same application.

Standard Ignition uses double wire bonds for stronger electrical connections and improved service life in high-vibration environments. The module’s heat-sinking design helps manage operating temperatures, while the polymer housing adds protection against moisture and vibration-related failure. For vehicles with weak crankshaft position sensor output, the module is designed to begin coil energizing quickly to support easier starting in cold weather.

Common Problems This Part Can Address

• No-start or hard-start conditions related to distributor ignition control failure
• Intermittent spark loss or engine stalling
• Misfire caused by unstable ignition module output
• Cold-weather starting issues tied to delayed coil energizing
• Heat- or vibration-related module breakdown

Installation Notes and Fitment Tips

• Fits 1985-1993 Chevrolet S10, N/A
• Fits 1985-1990 GMC S15, N/A
• Fits 1986-1991 Pontiac Sunbird, N/A
• Fits 1982-1986 Buick Century, N/A, with vehicles equipped with U.S. Emissions for Distributor Ignition Pickup
• Fits 1984-1986 Jeep Cherokee, N/A
• Fits 1984-1988 Buick Skyhawk, N/A
• Fits 1984-1984 Pontiac Fiero, N/A

Verify connector style, terminal count, and distributor configuration before installation. Some listed applications require specific emissions or distributor pickup setups, and certain fitments note blade-terminal variations. Confirm the vehicle’s original module layout and mounting location inside the distributor before replacing the part.
