jumper harness question
I have a jumper harness i bought from a friend and im not sure if somethings wrong with it.
I plugged in two different ECU's and they don't let the fuel pump turn on. Then i put the stock ecu in and it fires right up. What pins should i look for on the jumper harness. I already looked at the fuel relay pins and they are correct... Maybe there are some other pins i should check??? Maybe the ECU isn't turning on? Some one please point me in the direction. Thankss.
