New MAF Sensor.... Car won't start

Just wanted to know if someone had this in the past.
I got a check engine light on my 2013 Mustang GT which turned out to be P0103 and P0100.

I replaced the MAF sensor with a new OEM sensor yesterday and now the car wont start; if i removed the plug from the sensor the car starts. i already checked the voltage on the MAF plug and everything seems to be fine.

Any thoughts?

Put the old sensor in and see if it starts. The new one could be bad.

I already tried the old sensor and also a used one and i got the same results

Dumb question, but did you put the sensor in the correct direction? Im not sure if it can be put in bacward, just throwing it out there.
Can you hear the fuel pump running?
Clear the code and see what code comes back.
