Q: Vehicle start sometimes sometimes runs, and other time don't start. Run and shutdown! 2002 Toyota Sequoia

Vehicle start sometimes and other time won't start. When it does start it runs then shutdown

My car has 2407197 miles.
My car has an automatic transmission.

Hello - the first task is to extract problem codes, whether the Check Engine light is on or not. Most auto parts stores will do this for you for free on a "time-available" basis. These will greatly simplify diagnosis. If no codes are evident, checking for spark at the plug will help narrow the problem to ignition or fuel problems. A failing crankshaft position sensor can cause any/all of the problems you are experiencing, but won’t necessarily set a problem code. I recommend a no start inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.
