I've changed my fuel pump to a new one, but now i'm having a problem with rough idling, hesitation and even stalling.

Were you having a problem before you worked on it? How long since overall tune-up? Any applicable trouble codes? Use a gage and check fuel pressure.

I was having this problem before I worked on it. Have not had a tune up for eight months because I did not use it much. What should fuel pressure be?

Any mil codes? Sometimes you can get codes by cycling the ignition switch. You cycle the key just till the dash lites come on, no further. Cycle on--off, on--off, on, the the mil on the dash starts flashing, you count the flashes to get the codes. Your looking for two digit codes.

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
