For drivers searching for an ignition control module for 2005 Buick Century, 2004-2005 Pontiac Grand Am, or 2000-2004 Chevrolet Impala, the LX-346 is engineered to address common ignition failures with OE-style fitment and electronic control.

Key Features

• 12-volt ignition control module for external mounting locations
• Female connector design with 3 connectors and male blade terminals
• Built with double wire bonds for stronger electrical connections and improved durability
• Copper slug heat sinks help move heat away from the module
• High-temperature polymer housing helps reduce moisture intrusion and vibration damage
• Responds to weak crankshaft position sensor signals for quicker coil energizing in cold weather
• Durability tested through 500 thermal cycles from -40C to +125C

Detailed Description

Standard Ignition LX-346 is an ignition control module designed to restore proper spark timing and coil operation in vehicles using external ignition module mounting. It is a practical replacement for applications such as 2005 Chevrolet Monte Carlo, 2004 Oldsmobile Alero, and 1988-1999 Oldsmobile Cutlass, where ignition module failure can cause hard starting, intermittent stalling, or loss of spark. This part cross-references Delphi GN10125 for the same application.

Standard Ignition uses electronic ignition manufacturing experience and OE-level process control to produce modules that address common failure points found in original equipment designs. The LX-346 part number is also referenced as LX346T in interchange listings.

What This Part Helps Fix

• No-start or hard-start conditions caused by ignition module failure
• Intermittent misfire from unstable coil triggering
• Stalling or rough running linked to weak ignition signal response
• Heat-related module breakdown from poor thermal management
• Moisture- or vibration-related electrical faults in the ignition system

Installation Notes and Tips

Verify connector style, terminal count, and external mounting location before installation. This module uses a female connector with 3 connectors and male blade terminals, so matching the vehicle harness is important. Confirm the vehicle’s ignition system configuration and emissions notes where listed, including California emissions or Canada emissions applications, before ordering.

For fitment examples, this module fits 2005 Buick Century, 2004-2005 Buick Rendezvous, 2005 Chevrolet Impala, 2004-2005 Pontiac Montana, 1997-2003 Chevrolet Malibu, and 1987-1991 Pontiac 6000. It also fits 1993-1995 Isuzu Rodeo, 1992-1995 Isuzu Trooper, and 1994-1996 Honda Passport in listed applications.

Quality Assurance

Standard Ignition builds this module with double wire bonds, copper slug heat sinks, and a high-temperature polymer housing to support electrical stability and thermal durability. The LX-346 is tested through repeated thermal cycling to help verify performance across a wide temperature range and demanding operating conditions.
