Car repair cylinder pressure too low causing no start

 The car has been in the car park for a month today and now the vehicle won't start, so I'll see if I can get it fixed for him. The owner has just contacted the garage and the garage has come and checked it out and said they need to overhaul the engine.Let's get in the car and start it and see what the cause is. It's true that the car won't fire. There are generally three reasons why a car won't start, the circuit has to be normal, the oil circuit has to be normal and the cylinder pressure has to be sufficient so that the car can start properly. The circuit is relatively simple to check, we first check the circuit, lead out a spark plug, see if there is fire?


Do you see any spark? The circuit is normal, we then check the oil circuit, unplug the oil supply to the engine,

we find a bottle to catch it, start the vehicle to see if there is oil flowing out?

Do you see it? The fuel line is also normal, we put this fuel line back on him, pay a little attention when installing it, snap this tube card to the original position.

Our next step is to test the cylinder pressure, find some toilet paper, twist it into a ball,

stuff it into the hole of the spark plug, start the vehicle, normally, the paper will be able to fly out with a bang, but the car is slowly falling down, indicating that the cylinder pressure is insufficient, resulting in the vehicle can not start. We found the cause of the problem, the solution is easy, we took out all four spark plugs,

find a little oil, add a little oil to each cylinder, it is because he put the car for too long, the carbon inside the piston ring stuck, resulting in cylinder pressure is not enough, oil added to lubricate the piston ring, can also achieve the role of airtight. Then put all the spark plugs in, start the car, and it started successfully in one go. Is it very simple? Let the car owner run the highway, clean the carbon inside and learn a little car repair knowledge every day. Do-it-yourselfers can also repair their cars.

General this, can not start the vehicle, and can hear the starter in operation, which means that our battery and starter is no problem, we must consider the engine ignition and injection system is normal, we will start from a simple to check, in general, the probability of failure of the oil pump is the largest, we now find the fuse box in the airport, check whether the fuse of the oil pump is intact, we pull the fuse In fact, there are a lot of spare fuses in the fuse box,we use the above diagram to find the spare fuse and replace the damaged fuse on the fuel pump. After replacing the fuse, get in the car and start the vehicle, the ignition is successful, is it very simple? Learn car repair know...
