It would help if people filled out their profiles so that we knew what year car they have. Did you verify your findings at the fuel pump relay or did you just swap ECU's and determine this? If for whatever reason, the ECU is not operating the fuel pump, then you could tap into a keyed-hot wire off the ignition switch and use that to operate a relay which would in turn ground the fuel pump relay only when the key is in the on/start position. The only difference between this and how the ECU would operate the pump, is that when the key is in the on position, it only primes the pump with a 5 second running time and then it shuts back off until you start the car. With the relay bypass, the pump would stay on until you turned the key off. It sounds to me like you fried something in the ECU when you replaced the pump. BTW, I've felt the way Clay has before, and although sometimes that seems true, there have been times when I would have been up **** creek without a paddle if it weren't for people here on the forum. It's sort of hit and miss, and although it's not perfect I've seen worse. Try the Grand Am forums sometime, either people literally don't know Jack Schitt about their cars, or they simply don't care to help a guy out.
