Chevy Traverse Repair 2010

hello! I am new in this forum
I have a problem with my truck is a chevy traverse 2010, I turned on the engine inspection focus two days after putting green gasoline and a 20 pesos additive that they offer in the gas station (according to me to compensate the green) They took her in a crane, made change of injectors tried to turn on but, the motor inspection light began to flash very fast and no longer wanted to turn on as the march was stuck, she no longer gives marching or anything just the light was blinking in Friega. can anyone advise me for ???

Take it to the concessionary, because the car is in an emergency phase. From what everything says when you made green gasoline and the additive, take out all the fuel and look for some indication of fuel transformation, perhaps the Lambda (oxygen) sensors have broken down for what you made. Put gasoline again, the one that carries the original car and test.
