if you replaced fuel pump i would look at backward wiring when replaced and i would start at the source of work if your vehicle was working fine before replacement then 9 out of 10 it will be your fuel pump wireing
sometimes when putting wireing back together the connectors have the missing clip and in turn you can turn the wireing in both directions now where positive is touching the ground on both sides of connector kris kross problem check your work this is crucial use a test light to find the right wires where they go

It's located in the trunk on the drivers side. You should see a black and yellow sticker below a hole indicating that the fuel pump shut off switch is here. Even if your sticker has worn off, if it's a 92 topaz it most likely will be there in that hole. Shine a flashlight in it and you should see a black unit with a red button on top. Push the button down until it clicks in place. If the button is already down, your problem is something else.
