i have a 93 4runner and i have recently been having some issues with it dying and not starting up. i replaced the fuel pump thinking this would fix the problem, car ran fine for a short while and then died again. i have tested the power wires right next to the fuel pump and they are getting absolutely no power. all of the relays are good as well as the fuses. any ideas on what is going wrong? has anyone experienced this before? anythign at this piont would be great.
