Passat B5 startup problem

According to my B5 of 590,000 kilometers, I give you the following suggestions.

1: First, check the ignition coil of Gao Qi to see if the cylinder pressure is enough. Generally, good repair shops have this kind of instrument, with a pressure gauge on it, and all four cylinders can be read.

2. Clean the throttle and clean the carbon deposit inside the engine. You can choose fuel treasure, and hanging bottles is not recommended.

3. The nozzle may also be caused by insufficient oil injection from the nozzle. It may also be the oil pump, but the oil circuit is not smooth anyway.

4. Three-way catalytic blockage will also cause startup failure.

5. I suggest that the battery can be ignored, because it can strike a fire, and if you really can't find all the previous ones, you can also have a look.

6. I wonder if your car is shaking. If it is particularly shaky, the problem will be difficult. Either there is something wrong with the engine or the frisbee of the gearbox. It usually costs a lot of money.

When the car is old, all kinds of problems will be found, and there are too many possible factors. You can only check it step by step, starting with the simplest and cheapest. If you can't solve it, you must dismantle the engine and hoist the gearbox. At this time, you can budget the cost and see if it is suitable.
