مرحّل التحكم بالبخاخات معطل

The relay powering the injector control module or the injector bank, failed. The module commands it and monitors the result, so it reports a control circuit fault while the injectors themselves are untouched.

Failed open, the injectors have no supply and the engine will not run — a complete no-start with normal cranking and no injector activity. Welded closed is the quieter fault, leaving the circuit live with the ignition off, which flattens the battery over a few days and can leave injectors powered when they should not be. Substitute an identical relay as a first test, and if it has welded, measure the load — a shorted injector or module input draws above the relay's rating and welds the replacement too.
