Reply to "FF Suby Speedster broke down and flat towed."

I have an email in to Carey. I am stumped for now. I am getting zero voltage to the fuel pump and noticed a faint buzzing from the back of the car. I removed the rear seat cushion and exposed the ECU. The brown relay? box is buzzing when I turn the ignition to the start position. I did a scan with my scan gauge and it is showing a low voltage condition but I am getting 13.7 at the alternator post when the car isn't running of course. I am going to remove the drivers side rear wheel tomorrow and open the battery box and check the posts for tightness and corrosion. The battery is a small ATV battery in a custom made box mounted in the drivers side rear wheel well. My car was a challenge to convert to Subaru power. Carey said the ECU is very sensitive to voltage and if it is low will not work. Maybe I am not getting enough voltage to the ECU and it isn't telling the fuel pump to run? I am guessing now but I am curious to what the bussing means. I doubt it is anything good...
