Do-it-yourself repair of bad ignition problems in cars with leaking fuel injectors causing bad ignition

Today this car is every time you start, can not start at once, each time you have to play 2-3 times put to start, like this car is generally ignition or oil injection problems, we first take the spark plug out to check. There are many problems in the car, look at the colour of the spark plugs to know the reason, we will look at the colour of the spark plugs of this car in a moment.

1 cylinder 2 cylinders 3 cylinders 4 cylinders, the problem is obvious is not 1 cylinder 2 cylinders 4 cylinders, the colour is different from 3 cylinders, 3 cylinders of the colour is obviously lighter than the other three, and there is a great smell of gasoline, indicating that the problem lies in the 3 cylinders of the fuel injection nozzle. Use an oil pressure gauge to measure the oil pressure to verify whether it is the injector problem, connect it to this access port here, and then go to the car to open the key door, let the oil pressure up,

the oil pressure is now about 3 pressure, normally, he should be at 3 pressure, keep half an hour will not fall down, we look at the needle will not fall down, if it will fall down, it means that is the problem of the injector. After observing this oil pressure immediately

removed, see, after a few minutes, the oil pressure gauge is zero, indicating that there is indeed a leak in the injector nozzle, we give it a look to remove the injector nozzle out, now is a 3-cylinder injector nozzle leakage, leakage, then the mixture is too thick, the oil pressure is certainly not good firing. Then the cause of the problem has been found, the solution is not simple, then we go to the auto parts city to buy a replacement for him, buy a dismantled parts, only spent 5 yuan, see if the problem can be solved, and then the spark plug and ignition coil to it out. Let's see if we can start the vehicle at once. Well, it starts the vehicle at once every time. Isn't it easy to fix a car and do it yourself?
