Electronic Distributor Assembly Ignition (Blue Plug) Holden VN VP VQ 5.0L V8 - DA1003

Engineered for Holden VN, VP and VQ Commodore models fitted with the 5.0L V8 engine, the Electronic Distributor Assembly Ignition is a direct replacement unit designed to integrate seamlessly with the factory Engine Control Unit (ECU). Unlike earlier mechanical or vacuum-advance distributors, this assembly operates as part of the vehicle’s electronically managed ignition system, ensuring accurate timing control under all driving conditions. Purpose-built for Electronic Fuel Injection (EFI) applications, it restores reliable engine position signalling and consistent ignition performance — particularly important in vehicles experiencing intermittent stalling or hot no-start issues.

Key Features

• ECU-Integrated Operation: Works directly with the vehicle’s Engine Control Unit, which electronically calculates and adjusts ignition timing based on engine load and sensor input.
• Built-In Hall Effect Sensor: Features an internal Hall Effect pickup (blue connector block) that sends precise engine position and timing signals to the ECU for accurate spark delivery.
• No Vacuum Advance Required: As timing advance is fully computer-controlled, this distributor does not utilise a mechanical or vacuum advance mechanism.
• Resolves Common Failure Issues: Replaces the known weak point in these engines — the internal Hall Effect pickup — which can cause intermittent stalling, cutting out when hot, no-start conditions and erratic ignition timing signals.
• Complete Replacement Assembly: Supplied as a full distributor unit for straightforward installation, and a HEI-style cap to suit high-performance clip-on male-terminal leads, helping restore dependable ignition system performance.

Restore confidence in your Holden with the Electronic Distributor Assembly Ignition — a reliable replacement designed to maintain accurate ECU-controlled timing and dependable performance from your EFI-powered engine.
