02 ford focus flooding so no start. I pull fuse an it will eventually start. But runs outta gas. Driver fuel module. Under seat?

2.0L L4 DOHC
2.0L L4 SOHC

2.3L L4 Which engine does it have ? This vehicle also has a fuel pump driver module under the back seat . Suggest you check out youtube video on how to test . Haven't heard of that module going out on that vehicle , F-150 etc... an expedition where the module is mounted under the vehicle is real common . Watch this video on how to test the fuel pump at the driver module.

Do you hear the pump energize when you turn the key to on//// yes/no if yes fuel pump and driver module are good dirty filter suspected ///if no fuel pump driver module ,relay,fuse ,fuel pump, I'm not a diesel guy , gas my specialty but check for spark / power to glow plugs if you have an ignition module or idle air control valve look up a parts company where you are /country and search your vehicle parts in US ONLY GAS PARTS

remove and clean the idle sensor valve. pull out and clean the PCV valve (on top of the valve cover).blow out (from the inside) the air filter. do not apply gas until after your vehicle starts.

Hello Dennis weird,
My name is Francis, From Pretoria, South Africa.
I would like to ask some few questions please.... I have a 2007 Ford Focus ST.2.5, 6 speed Manuel. I bought the car from an Insurance salvage ..... After installing the Radiator which was out. i tried to start the car, it refuses to start, it just sounds like is about to start, then is not starting. I open the bonnet and check if the fuel will spins out as i would be trying to start it... Nothing came out. when i on turn the key no sound of the fuel pump then i went to the Real Right seat. and open it, I saw that the cable going inside the fuel tank which is connected to the fuel pump has a sockets which is not plug and it nothing was there. it looks like the fuel pump driver module was there and they stole it. i can see the other sockets half as they just pull out the module along with the cable. I have gone to Ford with my VIN for them to order the parts for me, they all seems not to know what i m looking for.... i have other Ford Focus ST of 2008 2009 2010 2011, there was nothing on that back seat... its just cables going inside the tank and out... Please i need help as i m already frustrated... Does any one have an Ideal of what i m talking about?

Yes they are the same, the job of the fuel pump driver module is an electric voltage regulator that varies the voltage supplied to the fuel pump to slow it down, this makes it run very quietly and does away with the whine at idle that some people find annoying as I have found from personnel shop experience at the Ford dealer I worked for for 20 years..

Hi, the Fuel Pump Driver Module communicates diagnostic information to the powertrain control module (PCM) through the Fuel Pump Monitor (FPM) circuit. This information is sent by the FPDM as a duty cycle signal which in turns controls the fuel pump.

Can you hear the fuel pump running? Just lay under the car or take the seat out and have someone turn the key on to see if the pump can be heard. You can take this pump out from inside of the car because it has an access plate in the floor. Just use a brass punch and hammer to spin the locking ring off.

Fuel pressure regulator might be the problem, the diaphram ruptures and the regulator leaks gas into intake, causing the engine to flood. Try holding the gas pedal to the floor while your cranking it. An easy way to tell is pull the vacuum line off the fuel pressure regulator if it's wet with gas or smells like gas that's the problem. It should be on the fuel rail, on top of the engine and looks like vacuum advance unit only smaller.

pull your spark plug wires and look down to the spark plugs and make sure there isnt water in the spark plug holes if there is just blow out with compressed air to dry out.
and make sure the air box has no water and free from any debris
good luck

i was once pulling a trailer with a ranger when it suddenly lost power and the engine died. turns out the problem was with the fuel shut off inertia switch. the switch is supposed to activate in case of accident. on my model the inertia switch is located in the passenger side under the glove box. dont know where yours is located. once you find it, just push the button and see if it resets. good luck.
