0 1 Buick Regal 3.0 automatic transmission, the motor didn't respond, the ignition switch came out with electricity, and the relay in the fuse box next to the engine disappeared.

..... Can the anti-theft of Buick's original car be useless? Joke: Buick anti-theft is a computer-controlled oil and electricity cut-off, which cannot be lifted. You didn't signal the computer to start the car, how can you start the car without oil pressure ignition ~! The initial judgment should be that the oil is cut off, otherwise 1 s cannot be touched. Make sure there is nothing wrong with the gear lever (whether it is N or P). To tell the truth, the wiring problem is hard to say. I can't tell you all the routes here clearly. But the most likely thing is that the fuse is blown and the gear lever is faulty. Simply put, how about you just short-circuit the relay?
