Hello, I have a 2016 Hyundai Elantra GT Manual car.. mileage 109,000. The car cranks, starts for 1 sec and then turns off. I am not sure what the problem is.. can you please advise? Thanks in advance.

What diagnostic codes did you see when you scanned it?


No code shows up because engine never fully turned over. Changed coils, spark plugs, crankshaft sensor, and cleaned throttle body. New battery.. not sure what the problem could be.

Stored codes are always a possibility but if you checked and there are none you have to roll with that.

Is the fuel filter clogged? Air filter? Is fuel pressure up to specification? Are the fuel injectors spraying?

Try a new MAP sensor - $75 available everywhere.

Look at live data, maybe something is off.

Is the fuel pressure correct? try checking that.
