:relays....if the other side has 12 volts positive...make sure it does...check fuses by battery if you're not getting power one side does have 12v but its not getting triggered by grounding the orange wire period. when i jump the 2 larger wires going to the relay everythign powers up but not untill i jump them. i have changed to know good relays from a running car and tested the ecu in the dead car in the same running car and it works fine. im beginning to think this thing has major wiring issues caused by the po and this kid just either needs to pay me big money to rip out the dash to find what got burnt up when he had smoke coming out of the dash or get the parts car he knows about so i can swap the wiring and go from there. i have already repaired at least 10 shorts under the hood 3 broken injector wires and several other sensor wires that were bare and grounding out and still no luck. he can get a complete car with blown engine for 300 so im thinking that will be his best bet ge it and swap his good engine into it and let me have the old car to strip and par out for doing the work for him
