Why Can't the Newly Replaced Igniter Get Fuel?
2 Answers
Newly replaced igniter cannot get fuel mainly due to dirty throttle, malfunctioning fuel pump, or insufficient oil pressure. Dirty Throttle: When carbon deposits on the throttle reach a certain level, it will cause air leakage in the compression chamber due to incomplete sealing, resulting in unstable engine idle speed, continuous high engine RPM, and difficulty in starting the engine, especially during cold starts. Malfunctioning Fuel Pump: If the fuel pump is damaged, it will directly cause the vehicle to be unable to drive. Poor performance may also lead to hesitation during acceleration. The failure often occurs without warning, making the vehicle unable to start, with no residual pressure, resulting in difficulty in starting. Insufficient Oil Pressure: Prolonged use can cause the engine oil to become dirty or viscous, preventing the oil pump from smoothly drawing in and pumping out the oil, leading to low oil pressure and consequently difficulty in starting the engine.
I've encountered similar issues before, like the engine not responding when accelerating after replacing the ignition coil. This is usually related to improper installation, such as loose wiring connections or incorrect pin connections, which can prevent signal transmission. Another possibility is that the new ignition coil itself is defective, with poor quality control during manufacturing. I remember one time I misdiagnosed the problem, only to find out later that the old spark plugs were too worn and incompatible with the new ignition coil. I recommend you first recheck the installation position and manually shake the wiring connectors to see if they're loose. If the problem persists, it's best to visit a repair shop and use a diagnostic scanner to check for error codes, ruling out other factors like insufficient fuel pressure or sensor failure. Don't force yourself to drive it—breaking down halfway is dangerous. This may seem minor, but details determine safety. Taking the time to double-check can save you from major trouble.
