i have a 2008 equinox 3.4. its giving me code p0205 for injector 5 circuit open. problem is the injector is just staying wide open dumping fuel into exhaust. i switched wiring from injector 5 to injector 6 and then 6 sprays fuel nonstop. so i know it electrical problem. i traced the ground wire all the way back to the computer and didnt see any breaks or bare spots in wire. could this be a bad ecm? dont know what else to check. thanks in advance
I'm not sure but does ECM ground the injector to fire it or does it power it to fire it. If ECM grounds injector to fire it than a short to ground would keep injector flowing. As 13nox said electrical testing is needed.
