2010 Yaris - not cranking - dash lights present.

[jools99]

Hi - have searched forums but not found much on this one.

Girlfriends 2010 manual Yaris (standard UK spec) - occasionally it won't crank the motor on the key - the dash lights are all lit ok - no warnings etc. battery is good.

It's completely quiet when the key is turned to the crank position - no click of the starter solenoid trying to engage and nothing from the starter motor.

She took it into the garage and they (apparently ?!) said they had changed the engine oil for thinner grade - saying something about the tappets causing this issue.

I'm a pretty practical guy so I can't figure out how oil & tappets could affect what looks like an electrical issue - unless someone can set me straight on a sensor or otherwise I don't know about ?

so please any suggestions appreciated.

thanks

Julian

Garage is bastards! :thumbsup:

Check the fuses first.

BAttery terminals clean?

I suspect an intermittent ignition switch. When it does it again remove key and hit it with a small hammer.

Try the key again.

Good luck! Tell us what happens!

Starter relay under the hood might be point to check ... locates in fuse box
