fuel pump in the tank, mkIII has an access panel under the mat for the spare, 3 screws ur there. back probe it, while u key up with a test light. bad igniters r fairly comon on 7m, not sure about 1jz.(pricey items though). also about 3 relays r related to ur fuel pump. fi relay, main fi relay, pump relay, curcuit opening relay. my advice, if u couldnt find the fuel pump, take it to a shop
