This model has a Tiptronic transmission; it has pump pressure and injection pulse, but there is no pulse to the coils. The coil terminals show ground and 12 volts, plus the terminal that controls from the computer is not sending the pulse

You need to check the crankshaft position sensor (CKP); it's an inductive type. If you have an oscilloscope, that would be ideal to determine if it's sending a signal to the car's ECU. It's also important to check the camshaft position sensor (CMP)

Hello, well I disagree on the topic. My question (immune), how is it? Does the light on the instrument panel come on and go off when you turn the ignition on, or not?

Hi, from what you're saying, the most likely cause of the lack of spark or the interruption is the crankshaft position sensor (CKP). This sensor is inductive. Also, the computer is probably damaged; remove it and inspect it thoroughly. You'll likely smell something burning
