2000 Toyota Tundra still does not run after changing mass flow sensor

Since it is not likely you have gotten two defective parts in a row .. We need to look elsewhere! .. *REMOVE* the top to air cleaner and inspect the air filter for possible rodent damage 'OR' for any foreign material at all 'on the top side' of the air filter that may interfere with air flow across the MAF sensor... It only takes a very 'tiny speck' of trash to foul up new sensor readings! .. (A VERY *TINY SPECK* OF TRASH)!

Thank you for your question I will attempt to answer it the best way I can without actually looking at the vehicle your vehicle needs to be placed on a Scanner with data stream you will be looking to isolate the electrical current at the mass air flow sensor there is a possibility that you have a defective mass air flow sensor Those sensors are sometimes sold as remanufactured you said you had gotten a new mass air flow sensor I would return it tell him it is defective this will ensure that the mass airflow sensor you bought is good or not you are more than welcome to bring your car to my shop free no charge diagnostic my location is 10 Cranbrook Boulevard in Enfield telephone number 860-265-3630
