Does not start

Audi A4 2002  157000 miles
I was manipulating the spark plugs coils when, suddenly, one of wires of the cylinder number 4 contacted with another and, apparently, that blocked the throttle body, as the engine has not started since then. Is there anyone who can give me a helping hand? Thank you in advance.

Try disconnecting the injectors wires and starting it that way. If it does, then connect the wires back and only start running the engine and accelerating the car. If this works, it is probable that the spark plugs harness is the one that is failing. Hope it helps you.

Electrical system failure

Audi A4 2002
In 2004, when driving a long distance, the vehicle suddenly lost power, the accelerator stopped responding with its evident risk, and the EPC light turned on. It was momentarily solved by changing 4 spark plugs and 4 ignition coils. But, after 20 days, the car started having the same failures again. I took it to another mechanic this time, who replaced the fuel pump and told me the spark plugs and ignition coils had nothing to do with my problem. Actually, he explained to me that my real problem with the fsi is in the fuel, which needs to be of 99 octanes. However, this fuel is not available in my country, so there is nothing I can do to solve it. So, check carefully before buying an fsi.
