Replaced fuel pump won't starr

Wasn't getting any power or fuel so we thought it was the fuel pump replaced it stil won't start not getting fuel to the engine

I was stopped at a light when the car just shut off didn't make any noise or anything Is how this problem occurred

sounds like you have a grounding problem. check the ground wire at the fuse box for corrosion,melted,loose connection. also,the grounds located under the windshield wiper cowling. Remove the cowling and there is a bolt with 3 grounds running to it. Remove and clean the grounds.also. remove main battery cover. Remove the BLACK ground cable on the right side of the battery. You will see a smaller box that the RED battery cable feeds to, with 5 smaller wires feeding out the back. Flip open the lid on the smaller box. Check the 5 smaller wires and make sure the connections are CLEAN/TIGHT. The first wire may be loose. Vibration from the engine would cause an arc and stall the engine.

We did all that yesterday also
