This part cross-references AC Delco 10482831 and Delphi DR140 for the same application. If you are searching for a 1990 Chevrolet Astro ignition control module, LX-363 is the part number to compare during diagnosis and replacement.

Common Problems This Part Can Address

• No-start or hard-start conditions related to ignition module failure
• Intermittent spark loss in distributor ignition systems
• Stalling caused by heat-related module breakdown
• Cold-weather starting issues tied to weak crankshaft sensor signal response
• Misfire or rough running from unstable coil energizing

Installation Notes and Tips

Verify the connector style, terminal count, and distributor mounting location before installation. Inspect the distributor, wiring, and crankshaft position sensor circuit for corrosion, heat damage, or loose terminals that could affect module performance. Clean mounting surfaces and confirm proper heat transfer at the distributor base to help the module operate as intended. For a 1990 Chevrolet Astro, confirm LX-363 matches the original connector and terminal layout before final assembly.
