What kind of sensor does Optispark distributor use?

Our optical sensor is built using components that are equal to or higher quality than the original equipment optical sensor found in factory-supplied distributors. Our Optispark distributor cap has a ventilation port cast into it with high quality brass terminals and high voltage distribution straps.

Why is the test light not working on my Optispark?

One wire is for ignition voltage and the other is coming from the ECM grounding the wire to open the injector. The test light cannot hurt the ECM if you touch the wire that does not light the test light. Probing one side of the fuel injector connector terminals will cause the test light to light. Crank the engine over.

What do you need to know about the Opti Spark distributor?

The Opti-Spark is a distributor with a two track optical position sensor, a keyed drive shaft, an ECM, a single ignition coil and driver and conventional secondary wires and park plugs. Contrary to what many people believe, most spark errors actually occur at low speeds, especially starting, not at high rpm.

Why is my Optispark engine not running properly?

The engine will lose power but it will not hurt the engine because no fuel is being introduced into the cylinders. If you find an ECM code 16 and the engine will not run the Optispark has failed and will need to be replaced. If you find a code 36 with the engine is running poorly, the most probable cause is a failed Optispark.

How long does it take to install Opti Spark on LT1?

Spark plug wires on the LT1 are a major effort. It usually takes around four hours. I would install the new Opti-Spark and when you’re sure the engine runs properly get started on the spark plugs and the spark plug wires.
