    Hello.
    Colleagues, after a stop, the car stopped firing. Economy Mode will appear immediately after the key, the radio does not work, the air conditioning does not work, the clocks go out after a few minutes. The injection opens because the candles are wet but there is no spark.
    Errors in the BSI only from the cabin lighting.
    There are no errors in the driver, what blocks it from firing?
    Which direction to go?
    Any hint will be valuable.

    There was no guy under the hood?

    You can't see anything, the car normally drove up to the shop and after returning such an action, earlier you could see that it was buried because the BSI with the seals torn off and the ECU described with a marker, however, was driving.
    Apparently, there was an attempt to fire with wires, so I allow the option that someone could have confused the poles, the diagnosis with the elements of the car is.

    And bsi and ecu what voltage "sees"?

    The least I noticed was 11.5V but the charged battery spins like crazy and then it's 12V with a hook.
    Does spilled BSI cause these symptoms?
    I only have x431 for diagnosis

    Well, measure the meter on the BSI as it is in reality.

    Checked on this connector with two thick wires and there is battery voltage, is there not a separate pin to which 12V could be applied to wake up the Economy?

    Well, but if you have 11V on the BSI power supply, do not expect correct operation.

    Will it be economy mode at 11V? Buddy, but can this be the reason for the lack of spark and the injectors are pounding with fuel?

    Take off the clamp to economy, you will turn it on for a moment. Since there was a cable test, the battery died? And these 307 don't like it, immo is pouring out, eeprom in general. Review ecu start permit, bsi number of keys, vin.

    Check the fuses under the hood, there is one responsible for ignition. It may just be an oxidized joint.

    All fuses checked, keys are entered, visible, there is permission to fire.

    Coil power and keying - what's up there?

    There is power supply to the coil, injectors, fuel pump, no keying.

    But you have injection keying because the candles are wet? I think it's a cable company.

    The candles are so wet that the shock, the rotation also sees, so it pours fuel.

    The coils don't key, do you think so? compression, timing. lexia can disable economy mode for an hour. And do a coil test to check the wires...

    Economy mode will not immobilize the engine, it only cuts off unnecessary receivers after ignition (radio, windows, etc.)

    No control pulses to the coil, would the timing cause no spark? Unfortunately, I only have x431 and I can't see there or I don't know how to turn off economy mode, the coil test is impossible, I get such a message from x431.

    I think so too, but why does it appear immediately after the key? Is it because the car did not start and thinks that only the ignition is on but not started and holds so as not to discharge the battery?

    And my colleagues, my mistake, I am very sorry engine 2.0

    Exactly, it will turn off the mode after starting the engine and recharging the battery.

    So I am only looking for the reason for the lack of spark, I also understand that BSI damage can be ruled out since the injections are pouring, so the immo does not hold?

    The coils were also replaced.

    Economy Mode the computer turns on when it detects a voltage drop on the battery, then only starting is possible, everything else is turned off. Maybe try connecting to a rectifier. And Peugeot Planet is best for diagnostics, only this way you can check the parameters thoroughly.

    Unfortunately, only x431 has it. I will review the coil bundle again, and the shaft and shaft sensors is probably the only possibility, I'm just surprised by the lack of spark during the injection operation, maybe the ECU has failed.

    I had a patient like this not long ago. The problem was that the car was driving and when you turned it off, it lost synchronization and immediately Economy Mode. Once it crashed and bsi because people tortured it with cables. Then new bsi, code and keys entered and supposedly ok. Battery charged and in a few days Economy mode again. Meter in hand and battery again not so much. So new bat. But there's still something wrong with loading. The cause was the brushes on the alcove.

    Ok, I understand only my friend, or if he loses immo synchronization, the injections work and only the spark dies?

    Okay, but the keys identify themselves in BSI, so I don't think it crashed.

    It does nothing, there is still Economy Mode.

    ECO Mode can be temporarily turned off PP200/DiagBox but it will not restore the spark.
    On older models, it was possible to trick the BSI and disable ECO Mode by disconnecting the excitation plug from the alternator.
    What year of this car?
    In BSI, the voltage drop erased the configuration memory, but in the pre-lift version.

Topic summary

The discussion revolves around a Peugeot 307SW 1.6 experiencing a failure to start, with symptoms including activation of Economy Mode, non-functioning AC and radio, and wet spark plugs indicating fuel injection without spark. The BSI (Built-in Systems Interface) shows errors related to cabin lighting, while no errors are present in the driver module. Participants suggest checking the voltage at the BSI and ECU, as low voltage (11V) could lead to Economy Mode activation and prevent proper operation. They recommend inspecting fuses, coil power, and keying signals, as well as considering potential issues with the ECU or wiring. The conversation highlights the importance of using appropriate diagnostic tools like Peugeot Planet for thorough analysis. The user ultimately seeks the root cause of the lack of spark, ruling out BSI damage due to fuel injection activity.
