12 ignition delay of new Regal gs is 5 seconds.
2, car carbon deposit or dirty parts.
A. Throttle: Carbon deposition in the throttle will affect the perception of throttle and air intake, leading to the delay or even error of computer transmission signal, which will lead to the failure to start the vehicle;
B. Nozzle: The nozzle is easy to stick some gum, which will block the normal fuel injection and cause poor atomization of gasoline, thus delaying ignition and making it difficult to start the car;
C. Spark plug: If the spark plug has more carbon deposit or the joint between metal and porcelain leaks, it will cause poor ignition;
D. battery: unclean battery terminals may also lead to poor conductivity, thus affecting ignition; Of course, insufficient battery power may also cause ignition start delay;
3. The starter relay is faulty;
4. The starting motor is faulty;
5. Improper oil viscosity: For example, in the case of very low temperature, the oil viscosity is high, which leads to slow oil circulation and dry mechanical friction, so it is difficult to start, which is very harmful to the car;
6. There is something wrong with the ignition switch;
7. There is something wrong with the solenoid valve of carbon canister: the ignition is weak after exposure, but there is no secondary ignition. Generally, there is something wrong with the solenoid valve of the carbon canister, because the gasoline transpiration is particularly large after exposure, and the valve of the carbon canister valve is not well sealed, which is easy to flood the cylinder or wet the wall.
8. There is something wrong with the ignition timing calibration;
9. Failure of camshaft sensor: If there is no problem with timing calibration, check whether the camshaft position sensor works normally;
10, insufficient oil pressure: insufficient oil pressure will be caused by the pressure relief of the gasoline pump and poor sealing of the fuel injector, thus prolonging the ignition time;
