Can you hook up a fuel pressure gauge after the fuel filter? You should see
about 13 psi as you start it up. May be a clogged filter. If your pressure is good
and then it stalls, do you still hear the fuel pump running?(I know you said you already replaced the pump).

If your pressure is less than 12 psi, move the gauge back between the filter and gas tank to make sure your filter isn't clogged.

If the filter is good then I'd suspect your low pressure is due to a bad fuel pressure regulator. It's located in the rear throttle body. Rebuild kits are available from Auto Zone, O'really and other outlets. Make sure it contains the diaghragm for the regulator.

Remember that CD Field Manual I sent you? Look in the electrical manual
and illustration 8A-21 and 22 show all the schematic for fuel pump.

Page 8A-18 on the right side of the page, is "How to get codes". I know you used
a code reader, but manually using a jumper has found me codes when the tool didn't. do you get a repeating of MORE than 3 sets of 1-2? (no codes available)?
