Electrical problem - intermittent no start when warm



I own a Toyota corolla 2005 . I had 4 occasions where the car would not start after I turned it off. If I let it sit and come back car starts. The electrical system was checked out but pep boys with no issue. Please help as to how I can figure out what issue is

About the Maintenance/Repairs category

When you say “car would not start”, do you mean you turn the ignition to start and nothing happens? Or, the engine cranks over but doesn’t fire?



Pep Boys (and other franchise shops) are no experts at this kind of problem.
I suggest you take it to a good independent shop or the dealer.
I suspect a relay or crank position sensor that fails when hot.


This could be the common Toyota worn starter solenoid contacts, if nothing happens when you turn the key. Pretty common after about 10 years.


My starter and my neighbor’s Toyota starter both did this at 100k miles. Replaced the starter with a Napa starter and no more problems. Toyota dealer wanted $400 for a starter. Way to much! https://www.amazon.com/TYC-1-17841-Corolla-Replacement-Starter/dp/B001KS9K5M/ref=sr_1_1?s=automotive&ie=UTF8&qid=1471265098&vehicle=2005-76-1013-------------0&sr=1-1&ymm=2005%3Atoyota%3Acorolla&keywords=2005+toyota+corolla+starter
