What is the reason why Poussin EFI truck has no high pressure fire?

There are many reasons for this, such as a damaged engine speed sensor, no ignition signal in the ECU, or a short circuit in the ignition fuse and no ignition power, or a damaged ignition.

The speed of the engine is related to the number of work times per unit time or the effective power of the engine, that is, the effective power of the engine changes with the different speeds. Therefore, when indicating the effective power of the engine, its corresponding speed must also be indicated. The effective power specified on the engine product label and its corresponding speed are called the rated power and the rated speed, respectively.

The working condition of the engine at the rated power and rated speed is called the calibration condition. The rated power is not the maximum power that the engine can emit, it is the maximum effective power use limit formulated according to the use of the engine. The nominal power value of the same type of engine is not the same when its use is different.

The effective torque also varies with the engine condition. Therefore, the maximum torque that the automobile engine can output and its corresponding speed are used as an index to evaluate the engine dynamics.

There are many reasons for this, such as a damaged engine speed sensor, no ignition signal in the ECU, or a short circuit in the ignition fuse, no ignition power, or a damaged ignition.

Focus on the camshaft and crankshaft position sensor, ignition coil, igniter and power supply line.

Summary. There are many reasons for this, such as a damaged engine speed sensor, no ignition signal in the ECU, or a short circuit in the ignition fuse and no ignition power, or a damaged ignition.

There are many reasons for this, such as damage to the engine speed sensor, no ignition in the ECU, no ignition signal, and ignition insurance, short circuit, no ignition power supply, or ignition damage.

The crank position has changed, the ignition coil has changed, and the ECU has changed.

Distributors, high-voltage wires, and spark plugs are all inspected on one side. If these are not broken, it is recommended that you change computers.

This car also has a distributor???

How not. This is a 08-year-old car, there is no distributor, there is a curved position, what does each of the three wires of the curved position mean, how many are electrified, what is the voltage, .

A computer provides a 5 volt voltage, a body with an iron wire, and a signal line to the computer including positive, negative, ignition pulse, and ignition circuit.

I just measured it, turned on the ignition switch, the first line of this curved position and the second line of the middle family (line 2) have a voltage of 5 volts, it is resistant to return ** There is a return question, how to check the gods, ask for high opinions, thank you.

There's no problem with that.

Probably not the problem.

1. Causes of oil supply system: low-pressure oil circuit blockage, loose pipeline oil leakage, high-pressure oil pipe with air, poor technical condition of fuel injector, incorrect fuel injection timing angle;

2. Reasons for starting device: power failure, poor contact of electromagnetic switch, poor contact between the commutator of the starter motor and brushes, and slippage of the clutch of the starter transmission mechanism;

3. Insufficient cylinder compression pressure: the remaining cylinder gasket is damaged, the balance socks are rolling, the valve is not closed tightly, the piston cylinder liner is worn and leaking;

4. Insufficient air intake: the air filter element is blocked.

There are several reasons why EFI engines do not have high-pressure sparks:

1. Causes of oil supply system: low-pressure oil circuit blockage, loose pipeline oil leakage, high-pressure oil pipe with air, poor technical condition of fuel injector, incorrect fuel injection timing angle;

2. Reasons for starting the device: power failure, poor contact of the electric magnetic switch, poor contact between the commutator and the brush, and slippage of the clutch of the transmission mechanism of the starter;

3. Insufficient cylinder compression pressure: the cylinder gasket is damaged and leaks, the valve is not closed tightly, and the piston cylinder liner is worn and leaking;

4. Insufficient air intake: the air filter element is blocked.

Hello, I'm helping you sort out the answer to your question, please wait a while Hello friend, if the engine has no oil and no fire, you have to check whether it is a problem caused by damage to the crankshaft position sensor? Replace the crankshaft position sensor with one, and you can read whether there is a fault in this engine**?

It feels like you can't get in the car.

Then you check it now, didn't it say that there is no fire, there is no oil yet? Then you can take a look, are you this eviction position sensor damaged? Or use a computer to check whether the engine is faulty**?

No fire, no oil? Is it that when starting, the engine does not respond at all? If you don't describe the fault phenomenon, thank you.

Problems with electrical circuits or ECUs, check the safety and trip computer.

The ECU is hung up, or the ECU power supply is poorly grounded, or the crankshaft has no signal.

What did you get in your car?

There are many reasons for this.

For example, the engine speed sensor is damaged.

The ECU has no ignition signal.

Another example is the ignition fuse short circuit and no ignition power supply.

Or the ignition is damaged.

There is an ignition control block on the left or right side of the wiper, look at it differently, and check the wiring.

There are many reasons for this.

1. The cylinder has a lot of carbon deposits, which causes the ignition to be untimely and not easy to start.

Maintenance method: Go to the repair shop to clean up the carbon deposits in the cylinder.

2. The oil is viscous, which makes it difficult to start.

Maintenance method: Change the engine oil and choose a fully synthetic one.
