I had the same issue, the problem was in the Ignition Switch. It short circuit from inside. So the whenever I clutched engine starts again and again.
You can either replace the Ignition Switch or open it up, and clean it properly. Worked for me.

Here's my first ever TECHNICAL problem with my Yaris and probably the first problem that I have ever come across that also has senior Toyota technicians STOMPED!

In order to start my car, I have to step on the clutch pedal all the way down to activate the safety switch behind the pedal.

If my ignition is on, to where all the lights on the dashboard are on, and I step on the clutch pedal all the way down, once I activate that safety switch behind the pedal, the car starts by itself without me even having to turn the key. (WEIRD)

Now if I leave my foot on the clutch pedal to where that switch is activated, the starter stays engaged.

Meaning, the starter is spinning on the flywheel while the engine is running.

Once I am driving and I press the clutch pedal all the way down to where it activates that safety switch so I can change gears, the starter engages itself while the engine is running. (ANNOYING)

Every time this happens the teeth on my starter is grinding on the teeth on the flywheel, hence damaging the teeth on both, slowly but surely.

Now because my car still has the original clutch on it, I have to press the clutch pedal all the way down to disengage the clutch so I can change gears.

I know it's an ELECTRICAL problem. But it has senior Toyota technicians who has been with Toyota for 25-27 years STOMPED!

Now before anyone suggests changing the safety switch behind the clutch pedal. Well that wouldn't make sense, because that switch is there to ONLY close the loop in the starting circuit of the car.

I've already changed the starter relay and still got the problem.

One technician suggested the starter ignition switch located by the steering wheel right where you put the key into the ignition. (Haven't done this as yet)

One technician also suggested checking the Body (GROUND) ECU located under the dash.(Haven't done this as yet, also)

Any other suggestions or RESOLUTIONS???

Thanx!
