Just replaced my fuel tank cause of leak now car stalls when try to drive for first time in morning had scanned got two code one is fuel level sensor and fuel temp sensor could it be bad pump

 

When you stomp it does it fall on its face? Reason I ask is if your fuel pump was reused which is fine to do but did you change the screen? If the screen internals are alreafy old, broken, or were damaged during the transplant the screen will collapse and starve the fuel pump. My Gle had this problem beforeit was mine and it was a pretty cheap fix...
