| Two other items must be taken into consideration: The Crank Sensor, and the Knock Sensor. These tell the computer the engine is ok to run, and either can disable the coils. While the Knock Sensor can usually be reset along with the computer, the crank sensor is polled by the computer at all times. To reset the computer, some models need the ignition turned on and off 3 times without trying to start, while others need the battery disconnected and a fuse pulled while the engine is rotated. The Crank Sensor SHOULD be located in the rear of the lower portion of the motor. It will have a hard plastic connector with (usually) only one wire going to it. |
