P1262 Chevrolet Code - Cylinder 2,3,5 and 8 High Voltage Circuit Fault
Quick Answer
The Fuel Injection Control Module (FICM) supplies high voltage to each fuel injector on the ignition voltage circuits. Common causes include Faulty Fuel Injection Control Module (FICM), Fuel Injection Control Module (FICM) harness is open or shorted, Fuel Injection Control Module (FICM) circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
