As Eric said, why not check the fuel pressure under load to see if that
is the problem before replacing more parts? Then when you solve it you
will know what you did that worked. A simple and cheap fuel pressure
gauge can be made from a dial/hose type tire gauge. I will send you more
details if you like. Even a true fuel pressure gauge is not that much $
compared to new fuel pumps.

We need to learn to diagnose our problems before throwing expensive
parts at them.
