IS200 won't start, no crank or click.

Recommended Posts

Hi there new to the forum, looking for some help to diagnose an issue. 

I have a 2002 IS200. 

I got in it the other day and suddenly it wouldn't start, not just wouldn't turn over but when I turned the key absolutely nothing happened, silence

The Battery is fine, and it is having this issue intermittently. After the first time I push started it, and when I got home and turned it off, it wouldn't turn back on. 

Since then I've started it maybe 20 times and it's fired first time every time, until last night when I had silence again. I would have thought if it was a dud starter then I wouldn't have managed to get it started so many times but I am a complete novice so feel free to tell me I'm wrong on that. 

I've tried with both of my keys, and the only other thing I've tried is pulling the EFI fuse (after reading another post on here) and after putting that back in it worked first time but I think it was just a coincidence, as I tried that last night and nothing. 

Any help would be hugely appreciated.

I'd hazard a guess at either a sticky starter solenoid or sticky starter motor as most likely, or perhaps an intermittent connection.

You'll need either a multimeter or at the very least a 12V bulb in a holder with wires attached to act as a test lamp.

When you turn the key, power is supplied on a relatively thin wire to the starter solenoid, which is essentially a big electromagnet. Once that magnet is energised it pulls a pair of big heavy contacts together that then allow power to flow on the big thick wires from the Battery to the starter motor.

The thick wire from the Battery to the solenoid should have 12V on it permanently, so check for that first. If that's OK then you need someone to turn the key to the 'Start' position while you check for the presence of 12V at one of the solenoid coil terminals.

Actually, my bacon butties are nearly ready so rather than risk an errant squidge of brown sauce or egg yolk dropping on the keyboard, it may be best if you have a look here at this website that will expain things better than I could do anyway.

Hmm.... just looking at that website and I think some things may have been lost in translation, for instance "sucking motor"??  :laughing:

It should give you some help though and there's bound to be some Youtube videos as well, so good luck.

When you say the engine doesn’t turn over just silence are the dash lights coming on or are they also off?

Dash lights are coming on, everything electrical inside the car works fine, lights are at full power etc

Looking like a meter job to find the cause then, if it’s automatic try putting the selector into neutral and see if it starts, if manual ignore the suggestion. 

Somewhere down the line you have either a broken connection to the starter motor, this begins at the ignition switch, usually a relay and ends at the starter motor. First check is to make sure all the motor connections are on and secure then work back.

If you were closer I would have taken a look for you being an electrician by trade.
