The vehicle cranks but absolutely does not start.

Hello, I've searched all the forums and the internet, but I haven't found the same problem. The car stalled while driving. We had it towed to a repair shop, which connected it to a computer and reported an ignition coil error. The ignition coil was replaced, but it still wouldn't start. The BSI control unit was then replaced, and the car ran for 200 km for a day without any problems. The next day, we pressed the ignition switch, but it still cranked but didn't start. This time, the crank sensor was replaced, but it still didn't work. Everything seems normal with the car. The fuel pump was also measured, and power was applied, and it worked, then it stopped working again. Now it doesn't work at all. It cranks, but it idles as if there's no gas. What could be causing the problem? Please help.

You didn't write the model information of the vehicle. But in Peugeot 406 and 307, if the signal lever is broken, it will generally start. The vehicle will not start or if there is wetness on the ground on the driver's side, the connector of the cables going to the computer passes through the ground. If it is wet, it may cause a short circuit and blow the FUSE on the engine side. This cable line may have an immobilizer in it. If you dropped the ignition key on the ground, the chip inside may have come loose. If it is a diesel, it may do this if the relay pressure sensor and its connector are disconnected.

Hello, it may be caused by the switch. Have the switch checked.
