What type of oil are you using? Sometimes using an oil of the wrong viscosity will cause abnormal oil pressures. Assuming the new oil pump and oil type are correct, my next guess would be severly worn internal engine components. Do the lifters still make noise?
The reason I ask if you removed the dist, is because it is what drives the oil pump. If the dist was somehow comprimised, then it could give the oil pump trouble.
