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 ---

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? Tester ---

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!

Doubtful. And unnecessarily expensive for diagnosing contacts inside a starter solenoid. Are you selling something? ---

Just curious, what is it that you are doubting @shanonia ? Who’s post are you referring to? I don’t see much in the way of controversy in the posts above. ---

It’s been removed. Someone had posted a link to an ad for a diagnostic tool for $699.95, saying that this would find the problem. ---

As Tester was asking… We need to know the type of symptom you had when it did not start. If you turned the key and just heard a “click”…its the internal starter solenoid contacts (very common) If it just cranked and turned the engine over and did not start up… that will be a different solution. But we definitely need to know. ---

This conversation ended in 2016. Then yesterday someone posted a spam advertisement, which I responded to, above. The spam has since been removed. Honda\_Blackbird does give helpful advice above, to anyone here for an intermittent no start problem.
