No power on ECU?

Hi,

If you look below, I attached the wiring schematic for the starter circuit. What I need you to do is this. First, confirm the starter fuse is good and has power to and from it.

The fuse is located under the hood in the power distribution box. When you check it, it is important to confirm power to and from it.

Next, make sure the clutch safety switch is working. There will be a black wire with a yellow tracer at the clutch switch. With the clutch pedal depressed, check that wire for power when the key is in the start position.

If that is good, I need you to go to the starter motor. At the starter motor, there is a heavy gauge black wire with a red tracer. That is direct from the battery and has power at all times. There will be a smaller gauge wire that is black. I need you to check if the smaller gauge wire gets power when the key is in the start position. You will need a helper for this.

Lastly, I need you to check pin 16 in the data link connector for power. If there is no power, check the 7.5 amp OBD fuse in the fuse box in the vehicle. See pic 5.

Let me know what you find

Take care,

Joe

Hi,

The black/yellow wire on the switch is power out after the clutch is depressed. There should be another wire. According to the schematic, it will either be red with a white tracer or black. With the key in the start position, does that wire get power? If it doesn't, that is an issue because that comes from the ignition switch.

Let me know if that has power with the key in the start position.

Is the AM 2 fuse good and have power to and from it?

Also, is there power from the black wire from the switch?

Let me know.

Hi,

Did you confirm there is no power to the black wire right at the switch itself? If there is, then we have an open between the ignition switch and the safety switch. If there isn't power at the switch.

At the switch, do you have power from the white/red wire from the AM2 fuse? If you do, turn the key to the start position and check the black wire for power.

Let me know exactly what you find
