Answer 1
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? -
Answer 2
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 -
