Whining/ humming noise and burning smell coming from the passenger front

What is your question?

The suv needs an alignment and a tuneup. Took it to the dealership for an oil change got it back and started to make that whining noise. Took it back and they said the noise was the fuel pump sending signals everywhere. It didn't make sense but went with being that I don't understand very much. Now a couple days later the noise sounds louder and started smelling a burning smell
