problems when i put gas, it has trouble starting. It hesitates to start.

What is your question?

when i put gas it has trouble starting, it hesitates. I took it to the mechanic and they changed gas pump, filter, fuel pressure sensor and it still does the same thing and the engine light is still on. Second opinion mechanic said he could not find the problem and that it had nothing to do with what they fixed.

What makes this problem better or worse?

Every time i fuel up its worse

How long has your 2017 Chevrolet Impala had this problem?
