You should first make sure the fuel filter is not installed backwards. If it is then turn it around. If filter is in correct then remove it and verify it is clear. You should be able to blow through the new filter. If not then replace the new filter again. As long as you did not do any other work that could cause it not to start then the only thing that can cause it is the fuel filter.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
Air pockets: When the fuel filter is replaced, it can create air pockets in the fuel system, which can prevent the engine from starting. To fix this, the air pockets need to be removed by bleeding the fuel system or using a priming pump.
You have a hard time starting car. If the problem is the fuel filter, and it isn`t changed soon, you may find that your vehicle won`t start at all. Misfire or rough idle. A dirty fuel filter could prevent the engine from getting enough fuel.
Stalling: If a clogged fuel filter goes unaddressed for too long, it may eventually cause the engine to stall as ideal fuel flow dwindles.
If you`re noticing that the engine does not start up easily, it may be due to a dirty air filter. An unclean air filter greatly impedes the amount of airflow to the engine, which in turn causes an overly rich air-fuel blend.
One common culprit for this problem is the crankshaft position sensor, which measures the position and speed of the crankshaft. The computer uses the information from this sensor to know when to fire the spark plugs. If the sensor isn`t working, the spark plugs won`t fire, keeping the engine from starting.
This usually means the battery is bad and incapable of handling a huge request for power to crank the engine over. Headlights begin white and bright, when you try to start the engine, they dim to nothing or almost nothing then as soon as you let go of the key, the headlights QUICKLY bounce back to white and bright.
1 Answer. No, you shouldn`t need to bleed a petrol system. If it was diesel, some require bleeding, because air pockets can act like cavitation points and it won`t pump the fuel.
Replacing the fuel filter will lead to an appropriate flow of fuel and air to the engine. This economizes fuel consumption and decreases emissions. Clean fuel is essential for optimal performance of the engine of your vehicle. The fuel filter removes dirt, rust, solids and other contaminants from the fuel.
Prime the fuel system by turning the ignition on (Run position) for 30 seconds, but do not start the engine. This allows the pump to prime the system. Turn the ignition off, and then crank it for 15 seconds.
A plugged fuel filter will restrict fuel flow to the engine. The drop in pressure may not be noticeable at idle, but as engine speed goes up, there may be a significant drop in pressure and a decrease in flow. The fuel filter is the fuel system`s first line of defense against contaminants.
If you install your filter in the wrong direction, air will have a hard time flowing through the filter`s material and your air handler will have to work overtime to make up for the loss of airflow. This is not only a waste of energy, but it can also possibly damage your air conditioner or heating system.
Without an air filter in place, the engine may also be sucking dirt and debris in at the same time. This can cause damage to internal engine parts, such as valves, pistons and cylinder walls. The result is excessive oil consumption, poor engine performance, and eventually engine failure.
The O2 sensor will not cause the no start. The no start can be caused by the fuel pump or the ignition system. You should check the engine for spark and fuel pressure, when it is not turning on to help narrow the problem down.
Such could be due to a big vacuum leak, an air induction fault like a stuck idle air control valve or, considering fuel, could be due to a failed temperature sensor that must be working properly to signal the PCM to enrich the mixture on cold start. Other common faults are defective spark plugs or a defective coil.
Restricted fuel supply to the engine might allow for proper fuel pressure while the engine is idling. However, when you`re accelerating or pulling a load, the demand for fuel is much greater. A blocked fuel filter prevents the fuel rail from staying full of fuel, restricting the amount of power your engine can produce.
