Remove the high-pressure fuel pipe of the first cylinder from the fuel injection pump. Have one person slowly rotate the crankshaft until it nearly reaches the fuel supply advance angle position of the first cylinder. Another person should carefully observe the oil surface at the outlet of the first cylinder's delivery valve. Stop rotating the crankshaft as soon as the oil surface begins to move upward. Remove the high-pressure fuel pipes of all four cylinders from the fuel injection pump, then remove the air bleed bolt on the fuel injection pump and install a specially processed adapter as needed. Attach a dial indicator.

What are the symptoms of a faulty engine igniter?

Symptoms of a faulty engine igniter: 1. The car may suddenly stall when using the igniter without obvious regularity, usually caused by poor contact in the igniter circuit or damaged wiring grounding; 2. After driving for a long time, the car may experience unstable stalling, but returns to normal after cooling down for a while. If this does not occur after using platinum, it is generally due to high-speed misfiring of the igniter chip, requiring replacement of the igniter; 3. The car operates normally before installing the igniter, but after installation and debugging, the idle speed becomes unstable during startup, and the engine shakes severely when accelerating, sometimes accompanied by backfiring from the exhaust pipe. If there is no improvement after adjusting the ignition timing, it is usually due to the sensor's red and black wires being reversed.
