i got 92 sc300 with a 2jz i bought it off of some kid and i guess they rigged the car to where the fuel pump is turned on using a switch in the car(poorly rigged) i traced it back to where the EFI relay is suppose to be and their was just a power and ground wires ran to the EFI terminals from the switch. the problem i am having is that if i pull out the wires from the EFI terminals and put in a relay the car wont run jus cranks.............. if any one has any advice or schmatics i can use to pin point my problem please feel free to help thanks in advance
