2019 Tundra hard start.

Early morning cold starts my Tundra chugs when it tries to start. (Remote start) The smell of excess fuel barrels out the pipe. Also, I noticed it's down 1 quart of oil @ 5k. Engine only has 10k on it. Could it be a stuck fuel injector?

 

Alcohol density sensor. There is a tsb for hard starts on flex fuel motors. It’s a simple update to the ecu.

As far as the oil, how are you determining you’re a quart low? The dipstick isn’t all too accurate. Unless you see blue smoke or have drips under the motor, Ide say nothings wrong and it’s most likely not burning or leaking oil.

Using 1 qt every 5k is within allowable limit by most manufacturers specifications. Check for leaks just to be sure. Let truck sit for a few minutes before checking level. Did you change it last? If not, are you sure whoever did put the correct amount in?
