If you change the control module do you have to reset the fuel pump.

A mechanic replaced muy control module and claims that the fuel pump needs replacing, but he never reset the vehicle after he did it. He took apart the fuel line under the hood. The truck tries to crank up but can't since the line under the hood is apart. I took a loose the battery and put it back on and I hear the pump. He took out th4e two metal lines up top that fit into two holes near the injection system. Need help told him to stop working on truck because I fear that he is messing up my truck.
