Ford Focus Fuel Pump Driver Module Problems

Electrical problem 2005 Ford Focus 4 cyl Front Wheel Drive Manual 240000 miles I have a 2005 Ford focus with the 2.0 liter Duratec motor and a manual transmission. When I go to start it, the motor will take 1-6 tries to start. It will very often 'start' but sputter as if running on one cylinder, and nothing I do with the throttle will change how it runs.

(When this happens I have to either wait for it to die on its own, or shut it off and try again). Occasionally when it finally starts, the starter will grind as if it wasn't expecting it to start so quickly. When I cycle the ignition, I can hear the fuel pump run for a few seconds, and when the car does finally start, it runs completely normally. I have used a scan tool to try and pull codes, but there are none stored. Also, there is no CEL, or warning lights coming on. I do most of my own work on my car, so I'm not shy about getting my hands dirty, I just lack the diagnostic tools to figure this one out. Ok, your right the new system uses what's called a fuel sensor which senses fuel temperature and pressure.

Ford Focus Fuel Pump Driver Module Problems

Voltage is variable at the pump according to the sensor's information. This solves the problem of fuel return line losses. Check the fuel sensor. It's located in the center of the fuel rail above the intake manifold. You'll notice a small rubber line coming from the center of the sensor- this provides vacuum to the sensor for whatever purpose that serves.

Remove that line, and sniff. If you smell fuel, then the fuel sensor is definitely bad.. You need to test for fuel pressure. As OBX has stated it sounds like you have a faulty FRP or FRT.

It could also be getting a weak signal occassionaly from the CKP Electronic Returnless Fuel System The electronic returnless fuel system consists of a fuel tank with reservoir, the fuel pump, the fuel rail pressure (FRP) sensor, the fuel filter, the fuel supply line, the fuel rail temperature (FRT) sensor, the fuel rail, the fuel injectors, and a Schrader valve/pressure test point. Operation of the system is as follows: The fuel delivery system is enabled during crank or running mode once the PCM receives a crankshaft position (CKP) sensor signal. The fuel pump logic is defined in the fuel system control strategy and is executed by the PCM. The PCM commands a duty cycle to the fuel pump driver module (FPDM).

The FPDM modulates the voltage to the fuel pump (FP) required to achieve the proper fuel pressure. Voltage for the fuel pump is supplied by the power relay or FPDM power supply relay. (For additional information on FPDM operation, refer to FUEL PUMP and FUEL PUMP MONITOR (FPM).) The fuel rail pressure (FRP) sensor provides the PCM with the current fuel rail pressure. The PCM uses this information to vary the duty cycle output to the FPDM to compensate for varying loads. The fuel rail temperature (FRT) sensor measures the current fuel temperatures in the fuel rail.

Ford Focus Fuel Pump Driver Module Problems

Ford has released a replacement fuel pump module, to address problems with it on a specific range of 2000-02 Focus vehicles built at two different Ford assembly plants. To accomplish this, the PCM sends instructions to the fuel pump driver module, located under the passenger seat. The driver module then.

This information is used to vary the fuel pressure and avoid fuel system vaporization. The fuel injector is a solenoid-operated valve that meters the fuel flow to each combustion cylinder. The fuel injector is opened and closed a constant number of times per crankshaft revolution. The amount of fuel is controlled by the length of time the fuel injector is held open. The injector is normally closed and is operated by 12-volt VPWR from the power relay. The ground signal is controlled by the PCM. A pressure test point valve (Schrader valve) is located on the fuel rail and is used to measure the fuel injector supply pressure for diagnostic procedures and repairs.

On vehicles not equipped with a Schrader valve, use the Rotunda Fuel Pressure Test Kit #134-R0087 or equivalent. There are 3 filtering or screening devices in the fuel delivery system. The intake sock is a fine, nylon mesh screen mounted on the intake side of the fuel pump. There is a fuel filter screen located at the fuel rail side of the fuel injector. The fuel filter assembly is located between the fuel pump and the pressure test point/Schrader valve. The fuel pump (FP) module is a device that contains the fuel pump and the fuel sender assembly. The fuel pump is located inside the reservoir and supplies fuel through the fuel pump module manifold to the engine and the fuel pump module jet pump.

The inertia fuel shut-off (IFS) switch is used to de-energize the fuel delivery secondary circuit in the event of a collision. The IFS switch is a safety device that should only be reset after a thorough inspection of the vehicle following a collision. 67: Fuel System - Electronic Returnless Fig. 68: Electronic Returnless Fuel System Schematic Diagram. Problem solved. OK, this is really weird, but I have a theory.

After a while the starter started to grind more and more, and eventually started to just 'click' when I would try to start it. So, I replaced the starter. So far, since replacing the starter, it hasn't sputtered even once. It starts immediately every time. I also noticed that the new starter spins faster than the old one (obviously because it's new).

So here is my theory. The crank sensor is either going bad, or isn't designed to pick up slower crank speeds. Since the older starter had slowly gotten weaker, I hadn't noticed, but maybe it wasn't cranking fast enough for the sensor.

The center for automotive safety is in a legal battle for ford to recall fuel pumps that fail sporadically on the focus I have a 2002 se and the fuel pump will briefly stop working sometimes and then kick right back in after a few littel jumps I have verified this with a fuel pressure gage monitoring the fuel pressure and watching it drop we all need to be aware of thsi problem and how to handle it if this situation arises on the road. Ford is fighting a recall tooth and nail disregarding our safety if your car is sputttering sometimes under acceleration it may be your fuel pump you can go to the center for automotive safety website to read more into this severe safety issue for now I am going to deal with it. Download Boardmaker V6 Crack. Unless my pump fails completely hopefully I can get 100 thousand miles out of my car and trade it in for something else. I'm thinking WRX or R32 skyline as my next car I even like some of the new scions.

Where you from dude. I went to PArkway in winston which also suck but they fixed it. Take your car to them with less that 1/4 tank of gas and let the know that when you turn hard right like getting on to the highway or when you got to get off light when you have to go under the bridge and back around again hard right it cuts off on you.

I dont know if your familar with winston but if your coming 40e to get on to 52s you have to go under and back around to get off. Well I done this one day ans stalled out right at the top of the bridge trying to merge onto 52s and I tried to cost out of the way but she didnt make it. I had to push the b i tch up a freaking hill and bout got squished between my bumber and speeding 18wheeler. Once on level ground she cranked up and I took straight to them at 10pm and they fixed it the next day under the saftey recall. Make sure you tell them a story like that.

Just had ours replaced at 93,000 miles. It was a 2000. Extended Coverage Program 03N01 covers the replacement on 00 and 01 models. 03N01 states, 'that some of the affected vehicles may experience engine hesitation, loss of power, surging, and other similar symptoms as a result of contamination of the fuel pump filters. Because the contamination of the filters is progressive, they may ultimately become sufficiently blocked to cause the engine to stall completely.

Although the symptoms noted above can occur under a variety of driving conditions, they are most likely to occur when there is less than one-quarter tank of fuel and/or when the driver is attempting to accelerate while making a right turn maneuver (such as entering a highway through a cloverleaf) or while driving uphill.' Supplement #2 to 03N01 states 'that if the customer states that their vehicle stalls, has engine hesitation, loss of power, surging, or other similar symptoms, the FDM is to be replaced. Ford has determined that there is no need for further diagnostics prior to replacement.

This program covers only the replacement of the FDM.' FDM = Fuel Delivery Module.

My car was driving fine in the morning on the way to work but on the way home as the fuel got lower it would cut out whenever I pulled out to pass someone. I only had the first 1/2-inch of the gas pedal to use. If I floored it, it stalled out. This was not cool when I pulled into the fast lane to pass only to stall out.

My dealer knew what the problem was and was happy to do it. In case you were wondering, supplement #1 to 03N01 just told the dummies at Ford to be sure and replace the old fuel pump with the new design and not just install an old one which was going to fail again. I pretty sure that there are no more old pumps in Ford's inventory anymore. I had the same problem with my 2001 zx3, I suggest you go to NHTSA and file a complaint. Maybe if enough people complain Ford would be forced to issue a recall or expand the replacement program. I have been fighting with customer service in Dearborn with no help. Cost me 500.00 to get it fixed because I was out of state when it died.

Letters were sent to 671,000 owners that extended the warranty on the fuel delivery module to ten years, unlimited mileage. Ford Customer Relationship Center 866-436-7332 NHTSA Safety Hotline - 888-327-4236 Good luck and spread the word.

Robear54, NHTSA is already aware of the issue on your 2001 (there're made aware of ANY field fixes that are published by every manufacturer, and they perform detailed reviews of any with potential safety implications) so sending them reports on a 2000-2001 won't do any good at this time. But the big question is: if yours is a 2001 model, why wasn't it covered under the program?? From what I've read every 2001 should be covered. I do have some contacts at Ford, and if you'd consider sending me your VIN I'll see if I can find someone that can get you an answer.

Robear54, thanks for providing the VIN. I'll send your VIN and your story off to my contacts in the morning and hopefully they'll be able to tell us why your fuel pump wasn't covered under the program.or hopefully they can tell us why should have been. Either way, you'll have the facts.

Please allow me a few days to get an answer since digging into something like this isn't part of their normal job, but I'm sure I can find someone who'll look into it as a favor. I just can't expect them to make it their #1 priority. Download Spore Full Thai Bit.
