سوختن فیوز مدار انژکتور

The fuse feeding a bank of injectors, blown so those cylinders receive no injection at all. The module commands them, sees no current, and reports the circuits — several at once, which is the signature.

Multiple injector circuits failing simultaneously is a shared supply, not several failed injectors. That inference saves the whole diagnosis, because working through the injectors individually finds nothing wrong with any of them. The engine will usually still run on the bank that still has power, badly and with a heavy misfire on one side.

A blown fuse is a symptom. One injector has shorted, or the harness has chafed to earth — so measure each winding's resistance and find the outlier before fitting a replacement. A new fuse into a shorted injector blows immediately, and repeated attempts damage the harness the fuse exists to protect.
