These pumps do fail, but you should verify that the fuel pressure is dropping, causing this problem before replacing any parts, just to avoid wasting your time and money.

do you have a step by step guide on how to replace the fuel pump?

my dads 1993 roadmaster does the same thing, lack of power, hard starting, etc. gonna test the fuel pressure first, the TBI does not have a fitting to plug the fuel pressure gauge, so you gotta 'T' it off on the main fuel line connecting to the throttle body. hope this helps
