Fuel Injector wiring diagram
Does anyone know where I can get a wiring diagram for the fuel injectors? I'm chasing down an electrical gremlin. My 06 Impala SS is throwing a P0204 code, Fuel injector circuit malfunction. It also throws the service traction control light and will of course runs rough.
But it will only do this on a warm start. On a cold start it runs like a champ, no matter how far the drive is. Shut it off then back on and it runs like ****. I did a quick swap of the fuel injector and it still throws the code. Voltage at the connector KOEO is 12.75v. Any diagram would or anyone who has encountered this same problem and shares their knowledge would be of great help. Thank you.

actually P0204 is fuel injector open circuit cyl # 4
Positive is always there and the computer switches the ground on/off as required (ground is most likely at fault) check the harness near/around that injector as critters like to get under the cover and chew.
