Question about 2004 Ford Focus

1 Answer

Fuel Problems To whom it may concern: I have recently developed a problem with my fuel system. I purchased some fuel from a common place and come to find out that the fuel filter had obtained the water. I then replaced the filter and now it died again and would not start could it be that it might either be the electrical grounding out or could it be i need to drain the fuel tank and start with a new one and replace the filter again? any help with this situation would be much appreciated.

    Thank you all for your help. After countless hours of troubleshooting the problem happened to be a Fuel pump control module was actually going out. After unplugging it and plugging it back in the problem was reset only to realize the problem later that day.

I think the tank has water and you will probably have to drain it. There are water removal fuel additives on the market, but I do not know if they work or not. you can buy them at any autoparts store.

Why my car will crank but wont start?


A crank no start concern is when your car has power to it, and when you try to start the car it will turn over but will not fire. There are two problems that are mostly associated with a crank no start concern. Starter is Bad.
If your starter has failed, you might get a crank no start concern. If you happen to be stranded somewhere, I would try to tap on the starter. This is an old trick used by those in the know, and sometimes it will work so you can get your vehicle to a repair facility. The reason for this is because when a starter fails, it usually binds up internally. Tapping on the starter will sometimes free the internal parts temporarily and allow you to crank and start the vehicle. If this doesn't work, you may have lost power to the starter and will have to have the vehicle towed.
Fuel Pump Failure.
Another common problem for a crank no start concern is a bad fuel pump. A fuel pump does exactly what it says, it pumps the fuel from the gas tank through the lines and to the motor. If your fuel pump is bad your car may just crank and crank, but won't start. Ironically a quick fix for this is the same as the starter. Try to tap on the fuel tank to get the car started. This may allow the vehicle to run on what's called false fuel for a while, or at least until you can get it to the repair facility. If this method fails, unfortunately it's time to get the vehicle towed.
Electrical Issues
These days most vehicles will have some form of security system in place. The most simple form of security often causes a lot of problems. If your electronic ignition switch has a security feature on it, it can fail and cause the vehicle not to start. Basically what happens, is the car thinks the wrong key is in the ignition and refuses to allow the vehicle to start. Really the only repair for something like this is to replace the entire ignition switch for faulty operation.

Does your car stop running after a short time, and start again after you wait a...


I've seen many questions in the vehicle section that concern this problem, and there is an almost universal answer.

On an older vehicle, the fuel pump is often quite worn out, and it is never checked, because of accesability issues.

When they start to fail due to perfectly normal wear and tear, the common symptom is a temporary "failure" while driving. The car can usually be driven again after the fuel pump cools down and operates normally again, usually 15 - 30 minutes.

There are three items that must be replaced when this happens. First of all is the fuel pump itself, and anything else that is replaceable in the tank that concerns the fuel system.

Second, is the fuel filter, just as a matter of course.

Third is the fuel pump relay, as they tend to fail at the same time as the pump, if not sooner.

I hope this answers many of the problems that you, the readers, are having with your cars.

Hi, I purchased a 06 volvo v50 t5 and had the car checked out and everything was OK and now about a week later the engine light came on, so took it back and the mech said its the fuel sensor. The car acts...


You should have checkup with the turbo air and fuel supply system . Its not the problem of the sensor . Its is the problem concerning fuel injection system . In india such a repair or replacement of the FI system of ur car would cost almost 20000 INR divided by 50 would give you the approx amount in us$. So the fuel injection systems JET inlet pin should be faulty .

With growing fuel costs and problems of global warming that are being faced by our planet, automotive industry is trying its best to create cars and engines that are more fuel efficient. In a recent news release Chevrolet unveiled the working of The Air Shutter system which is going to be used in the much awaited Chevrolet Cruze Eco model giving it a decently good fuel economy of 40MPG or 17 kmpl.

Air Shutter System Working Greg Fadler, aerodynamics engineering group manager at Chevrolet and his team developed The Air Shutter system to make 2011 Chevrolet Cruze Eco one of the most fuel efficient small cars on the market achieving almost hybrid like fuel economy without the Hybrid cost and maintenance. This was achieved by using commonly used techniques of reducing overall weight and ride height to provide it the aerodynamic benefit. chevrolet+cruze+eco+air+shutter.gif
The real innovation is the front grill which has an automatic shutter system that senses wind flow and temperature conditions with sensors which, are connected to small electric motors that open and close the shutter as and when needed. When the car is moving at slow speed (city driving) the shutters open to provide maximum air flow to the engine for cooling thus, reducing radiator power consumption. The shutter remain closed during high speeds (highway driving), providing an increase in half a mile per gallon in combined city and highway driving.
The system however doesn't compromise with engine cooling in anyway. The system in fact helps to provide maximum cooing in the worst of conditions with the advantage of increased fuel economy.

My 1995 Acura Integra starts running roughly at 3500 rpms. Kept below 3500 rpms, it runs fine with no problems. It just started doing this. Never before. It seems there is somekind of govenor that kicks in...


If the fuel filter hasn't been changed in the last 2 years, that is a good place to start. Also,have you given it a full tune-up recently? those are the easy suggestions. Typically the major stuff shows up with a "check engine light" indication. My '97 Civic acted similarly to this, and it ended up being the fuel filter(at 167,00 miles). Cap/rotor/plugs or other ignition system faults will also limit high rev performance. When in doubt, Autozone will check your computer system for no charge if you're concerned about sending good money after bad.

When the misfire monitor detects a misfire, it will trigger the check engine light with the specific cylinder number as the last digit in the P030X code. For instance cylinder 1 misfire is P0301, cylinder 2 is P0302 etc.

The misfire detection monitor, a software strategy built into the computer, is designed to detect an engine misfire. The computer can also normally identify the specific cylinder in which the misfire has occurred. A misfire is nothing more than a lack of combustion, which can be caused by poor fuel quality or metering, low compression, lack of spark or unmetered air entering the engine. There are other possible, less obvious causes as well, such as uncommanded Exhaust Gas Recirculatin (EGR), flow.



P0301:

Possible Causes:
Fuel injectors, related wiring, sensors and computer issues
Running out of gas, or poor fuel quality
Evaporative emissions system (EVAP) concerns: fuel vapors leaking into engine
Incorrect Fuel Pressure
EGR system concerns: leaking EGR valve or restricted ports
Base engine concerns: low compression, valve train problems and timing issues
Ignition system concerns including, but not limited to:
Faulty spark plugs
Faulty coil or related wiring
Ignition module or related wiring issues
Ignition related sensor faults or wiring issues

P0302:

Possible Causes:

Maybe the fuel pump??


hey wmezzetti, the fuel pump is located under the rear seat on the passenger side. you should see an access cover held in place with a few screws. under the cover is the pump held in place with a locking ring.when you replaced the pump, did you replace the filter? sometimes the filter gets contaminted. I would make sure the fuel pressure is ok, and also make sure your exhaust system is not restricted. another possibility is a torn intake boot causing a large vacuum leak.the boot can develope a hole at the small hose that tee's into the main boot. you can check it by feeling that area of the boot with your fingers. these are the most common problems I see, especially if there are no faults stored in the DME.
