1999 Buick Regal

car starts up and runs fine for the day but tried to started again after work and it wont start, the engine do turn over when I turn the key. It seems like no fuel
going through. I had the fuel relay replace and the fuel resister re-routed because of heat and it worked fine for that day but the next day it didn't start up. I do suspect
it's the fuel pump. Question is how do I change the fuel pump? I need a step by step instructions to replace it.
Please help.

Before replacing it, have you checked fuel pump pressure when it doesn't start? I would recommend making sure it is bad before you replace it. It isn't a fun job.

Here is a how to for checking:

The problem has been resolved. It was the "new" fuel pump, defective. Ordered another car started right up.
