The first thing I would check would be the catylatic converter to make sure it isn't plugged. Check it at night after driving to see if it is glowing red hot. IF it is, it's plugged. If things appear ok there, move to the fuel pump pressure.

LEt me know about the converter. We'll move on if that appears okay.
