Hey Scotty I have a 2014 corolla and have been having an extended crank in my car for a while now and I have just been changing a lot of parts for it like the spark plugs ,starter I got a new battery I took it to toyota they didn’t know either all they did was clean the throttle body and went the next day they said they checked the fuel pump , the fuel ingectors and other things aswell and said they needed to do another diagnostic so id really appreciate your help thank you
Mention all the codes here, when the car is scanned next.
Extended crank?,are you sure is not a Honda Civic?
Well often it's a weak mass airflow sensor I would clean it with mass air flow sensor first it's in my video make your car run better with a little spray cleaner Scotty. If that's not it try some b and g fuel injector cleaner in the gas tank could be dirty injectors
It seems to be a fuel issue. Have another mechanic to check the fuel line pressure.
