How long since a tune-up? Any applicable mil codes? Use a gage and check proper fuel pressure. If you have the spider fuel system, that system is known for problems. You may have to check fuel injector and fuel poppets. Was the gas tank clean when you replaced the pump? Did you check for good voltage and ground at the pump?
