Make sure all the connectors are really plugged in.
Sometimes the PCM plugs won't seat fully and need to be wiggled and reseated.

I may want to get an OBD-2 code reader it does run scans on the emission sensors( fumes capture, evap, ehxaust recirculation....). there are too many things going on at once to really pinpoint the exact problem. I tried.

If the brushes in the starter are worn out then the solenoid on the starter can't work.It needs to go to ground through the brushes to engage,i suggest that you replace the brushes in the starter.If i'm wrong then you need a starter solenoid switch,the one on the starter.

SOURCE: Car won't start on first

What type of battery was it replaced with? Was it sold with a good charge i.e. was it second hand?
Fuel pump is a separate issue. My experience of Fords is that the pump can generally be heard near the fuel tank. Ensure there's enough fuel in the tank as this may be the reason for increased noise.

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


Driver fuel module ???? Under the back seat ? The part your calling a driver fuel module is the fuel pump driver module ! What fuse do you pull ? If you would like help you need to go into more details . Your vehicle has electronic returnless fuel system (computer controlled ) Having the vehicle checked for DTC'S - diagnostic trouble codes could shed some light on to the problem . There is a fuel pressure sensor on the fuel injector fuel rail ,this is a input to the PCM engine computer .The PCM talks to the FPDM -fuel pump driver module to speed up or slow down the fuel pump .

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

the MAF (mass air flow) meter may be faulty, this is typical of the symptoms you are getting. It is just after the air filter in the large bore pipe leading to the inlet on the engine, not a cheap part but you may get one on ebay, just remove and unplug the original and swap it.
