My car wont crank after I installed new fuel filter

My fuel filter had a pinhole in the bottom of it so I replaced the fuel filter and now my car wont start at all. It was running fine before I changed it.

My car has 180000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
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.
Bad Sensors

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.

Fuel pressure
ANSWER : Hello,
You may want to try checking the fuel pump relay. The relay wires should have ground on two wires, power on one wire and switched power on another wire. To activate the fuel pump your ECU actually connects one of the ground wires to complete the circuit and send power to the fuel pump. If the wires all have power running through them, then it is likely you have a faulty relay. The wire coming from the fuel pump is the other ground wire. I would recommend having an expert from YourMechanic come to your location to diagnose your wiring as this can be very difficult and time consuming without the proper wiring diagram.

I installed a new fuel pump on a 1997 dodge caravan, it turns on but no gas is getting to the engine. Access to the fuel filter is
ANSWER : Hi there. It sounds like the fuel filter being corroded is the issue. It will need to be removed as well as any lines that may be corroded. You may have to replace a good portion of the lines if there is a lot of corrosion. If the vehicle cannot be serviced where it is then fuel lines can be used but they need to be able to handle over 50 psi. You would be best to get some assistance from a certified mechanic, like one from YourMechanic, that can come to you to [replace the fuel filter and lines] https://www.yourmechanic.com/services/fuel-filter-replacement

My car cranks but will not start. I try to do fix the car myself. I put new battery, new alternator, and new ignition coils.
ANSWER : Hi there. Check the spark plugs and see if they are worn or burned. If the plugs are good and they have a good spark, then the engine compression could be low causing a no start situation. If the spark plugs are not emitting a spark, then the crankshaft position sensor could have failed or disconnected. Check the crankshaft position sensor wiring harness and make sure that its plugged in. Check the sensor and make sure that its not broken or damaged. If you need further assistance with your engine not starting, then seek out a professional, such as one from Your Mechanic, to help you.

Installed new delphi fuel pump and fram fuel filter. still no pressure on fuel rail valve and wont start. 2003 Chevrolet Tahoe
ANSWER : Hi there – I suspect you have weak power getting to the fuel pump. I would first check the voltage coming out of the fuel pump relay. If the contacts in the relay are burned, you will not get reliable current flow to the pump. Check the fuel pump ground as well (voltage drop across the ground, not just continuity). I recommend a fuel system inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

I put new throttle position sensor on now the car wont start i connected everything back on correctly so why wont it crank now ?
ANSWER : Hey there. Replacement of the throttle position sensor on your vehicle is pretty straight forward. There is no adjustment to be made – just remove and replace the sensor and you should be done. If the vehicle isn’t starting, you left something disconnected or there is a separate issue all together. If all of the work has been double checked and you still can’t get to the bottom of it then it is likely another problem that is occurring that is causing it to fail. You’ll want to see if the computer is still indicating a bad sensor even with the new one on. There are other sensors that could be causing the car to go into limp mode, such as a problem with the fuel system or another sensor on the vehicle. I recommend having another expert diagnose the starting problem so that this can be addressed properly.

To replace a fuel filter or not ? Vehicle had no fuel when bought; added fuel & it started, but should the filter be changed…
ANSWER : Hello, thank you for writing in. Your head is in the right place. While gas these days is held to some better standards, its very possible to collect debris in the tank over time. Considering the mileage on the vehicle, replacing the fuel filter is a great idea anyway, and you should definitely do so. They are quick and easy to do, but you need to be careful with the fuel lines. Also make sure you install the filter in the correct direction. If your fuel pump is original, then you may want to consider replacing it as well. Running a vehicle to empty can hurt the pump. It is also a great time to inspect the tank for debris. For more help replacing either fuel component, contact our service department to schedule an appointment.

I have a truck that won’t run and is not getting gas to the engine. Fuel pump is running, have a new filter and new fuel pressure
ANSWER : Hi There,
It sounds like you may have a clogged fuel injector or potentially a faulty injector that is fried internally. I would suggest testing them if you have access to a multi meter. Disconnect the injector from the electrical connector and set your multi meter to Ohms mode and measure the resistance of the injector. After testing all injectors, compare the resistance. They should be the same or very close. If they are not, they will likely need to be replaced.
