Check that terminal contacts have been pushed down evenly in connector.

Check main power supply by connecting a voltmeter between pin 5 (brown) in ECU connector and ground.

Reading: approx. 12 volts

If no voltage registers, check wire between ECU and fuse-box located behind the center console ash tray. Check fuse #1 and wiring to battery
(incl. battery terminals). Repair as necessary.

Check ignition coil and power stage by disconnecting connectors.

Remove the two mounting bolts (Torx) and separate the ignition coil from the power stage.

Measuring Positive And Negative Side Of Coil
