It is possible the fuel pump failed again, a easy quick test is to see if it runs on starting fluid. If it runs on starting fluid this proves problem is fuel related. Next step would be to check fuel pressure, if low replace filter and check again. If still low then verify pump has good power/ground when trying to start and then replace the pump. Let me know if you have more questions or i you would like replacement instructions, you can reply to this answer at any time without additional fees. Thanks.
