Chevrolet 1985-1995 V6 (262) EFI Distributor

• Direct factory replacement for 1986–1995 GM 4.3L V6 EFI — no ignition box required

• Magnetic pick-up trigger with 35,000+ V output for consistent spark across the RPM range

• Computer-controlled advance — retains factory ECM timing control on EFI applications

• Machined aluminum housing with steel gear — built for long-term durability in V6 trucks and vans

If your 1986–1995 Chevrolet S-10, Blazer, Astro, GMC Sonoma, Jimmy, or Safari is experiencing rough idle, misfires, weak spark, or ignition timing inconsistency, a worn or failing distributor is one of the most common causes. This TSP distributor is engineered as a direct factory-style replacement for the computer-controlled distributor used in GM's 90° 4.3L V6 (262 CID) EFI applications — restoring factory-spec signal accuracy and reliable spark delivery without ECM reprogramming or additional ignition modules.

Built around a magnetic pick-up trigger and a machined aluminum housing, this distributor is designed to provide accurate crankshaft position signaling to the ECM while supporting a 35,000+ volt external coil output. The computer-controlled advance retains full integration with the factory EFI system, making this an ideal solution for stock restorations, daily drivers, and light-duty performance rebuilds where factory ignition management must be preserved.

No ignition box is required. The distributor installs with a male terminal connection and is compatible with external coil setups. A steel distributor gear is included and is suitable for use with factory camshaft specifications in compatible 4.3L V6 applications.

Applications
Designed for GM 90° V6 engines — 4.3L / 262 CID — in 1986–1995 model year applications. Confirmed common fitment includes Chevrolet S-10, Blazer, and Astro; GMC Sonoma, Jimmy, and Safari. Functions as a direct replacement for the factory computer-controlled factory distributor used in these EFI-equipped trucks and vans.

Is this a direct replacement for my factory 1986–1995 GM 4.3L V6 EFI distributor?
Yes. This distributor is engineered as a direct factory-style replacement for the computer-controlled distributor used in 1986–1995 GM 90° 4.3L V6 (262 CID) EFI applications, including the Chevrolet S-10, Blazer, Astro, GMC Sonoma, Jimmy, and Safari.

Do I need an ignition control module or ignition box with this distributor?
No. No aftermarket ignition box is required. This distributor is designed to work with the factory ECM and external ignition coil without requiring additional ignition modules.

Will this distributor work with my factory EFI and ECM?
Yes. This distributor uses a computer-controlled advance and magnetic pickup trigger that integrates directly with the factory EFI system and ECM, preserving factory ignition timing control without requiring reprogramming.

What coil is compatible with this distributor?
This distributor requires an external ignition coil, which is not included. It is designed for use with external ignition coils compatible with the GM 4.3L V6 EFI ignition system. Verify compatibility with your existing ignition components before ordering.

Is the distributor gear compatible with my camshaft?
This distributor includes a steel distributor gear. Steel gears are compatible with cast iron and most factory camshafts. If your engine has an aftermarket roller camshaft or requires a bronze or specialty distributor gear, verify gear material compatibility with your camshaft manufacturer before installation.

Does this distributor fit the 4WD version of the S-10 or Blazer?
Yes. This distributor is designed for the GM 4.3L V6 (262 CID) engine family used in 1986–1995 trucks and SUVs, including four-wheel-drive models. Verify your vehicle's original distributor part number or application before installation to confirm compatibility.

What electrical system does this distributor require?
This distributor requires a 12-volt electrical system with a functioning alternator. It is not compatible with 6-volt electrical systems, generator-equipped vehicles, or ballast resistor ignition circuits.

Does this distributor fit the Chevy Astro or GMC Safari van?
Yes. The 1986–1995 Chevrolet Astro and GMC Safari equipped with the 4.3L V6 (262 CID) are confirmed applications for this distributor.

Do I need to set ignition timing after installing this distributor?
Yes. After installation, ignition timing should be verified and the distributor installed according to your vehicle's factory service procedure. On EFI applications, the ECM controls ignition advance, so proper distributor indexing and camshaft synchronization are essential for correct operation.

Is this distributor compatible with a performance or rebuilt 4.3L V6?
This distributor is designed for stock and factory-style EFI ignition systems used on the GM 4.3L V6. It is an excellent choice for restorations, stock replacements, and daily-driver rebuilds that retain the factory EFI and ECM. For heavily modified engines with custom ignition timing requirements, verify that a computer-controlled distributor is appropriate for your specific combination.
