Re: fuel pump
You might have a vacuum leak. Spray carb cleaner in small bursts around the perimeter of the intake and where the TBI ttaches to the intake. If it speeds up, it has a vacuum leak. You might also check for leaks around the EGR valve. Mine had a bad vacuum leak there once.

Re: fuel pump
There are many things that can cause a rough idle but have you cleaned or changed the EGR valve ? Just a thought . Frank
