So I've been told there are some gurus in here thst could help me I have a 2001 2500 spd 4x4 and the ecm took a squat well it was working just went nuts whenever it decided to I made the mistake of trying to have it rebuilt and we all know that horror story to make a long story short I bought another ecm from someone that said everything was running smooth I plugged it in and now the fuel gauge isn't working I'm getting codes 0370 and 0575 granted the truck runs fine just wondering if there's something I can do or is it a lost cause and if anyone may have one of these laying around that's in full functional condition I might be interested in
