Re: Need help Please-Knock sensor control unit
The knock sensor is wired straight to the engine computer, I don't know of a knock sensor control unit. I take it that you have no spark. The best first step is to pull the 3-wire distributor harness & turn on the ignition & check for 12V between the outer two wires. If that's good then re-plug the connector & backprobe the center wire with a LED test light hooked to battery positive & crank the engine. The light should flash or the Hall sensor in the distributor is bad.
