i have a 92 cx with d16z6. i just put the motor in. when i turn the key to on it pops the fuel pump fuses everytime. i tried a different ecu and main relay. no spark or fuel. i was guessing short in the wire. if that might be it then can i have some sort of direction on where to start. i checked continuity on the main relay plug but i dont know which wires should be grounded and which ones not. any help will be much appreciated
