Question about 2001 Ford Focus
My 2001 Ford Focus suddenly would not start. the engine would turn over. I was told it was the Fuel Pump. I've replaced the fuel pump, fuel filter, fuel regulator, Fuel relay, new spark plugs & wires, the Mass Air Flow, & new air filter (I tested it during the process & only got a code back for Mass Air flow ) It finally started, sounded great, went for a test drive. I didn't get 1 mile, & the red battery light came on & the car died. it did start again if I didn't give it any gas. But as soon as I put it in Drive & gave it gas, it would die. I did it back into the garage, but now again, it will not start. I'm begging for help!!! PLEASE!

It sounds from your description that the fuel pump is weak. To check the fuel pressure you need a fuel pressure test gauge for fuel injection. Attach the gauge to the test port schrader valve and turn the ignition to the on position. Record the reading. Now start the engine and record that reading. Unplug the pressure regulator vacuum line and record the reading.
The pump should have pressure with in specs but if low, start with the installation of a new complete pump. It is located in the fuel tank. Also replace your fuel filter.
Hope this helps you.

SOURCE: TOO LEAN CODES
yes very very common code for these motors i get them all the time. now the first thing i do is listen to the pcv valve for noise if it is rattling this is the problem and is the most common of all. another thing is the intakes leak from cracks in them but the only way to find it is with a smoke machine. now the one other thing i have seen before is debre like a leaf in the mass air flow sensor but you have replaced it so most likely no that.
do your self a favor and change the pcv valve it only cost under 5 dollars. if this is not it you will need to find the leak in and around the intake or a vacuum hose.
because you have two lean banks this mean if it is a leak then it has to be in common with both banks and that is the vacuum line system intake etc...
let mew know if you have any more question. good luck man

This valve can become sticky with deposits. shoot some spray carb cleaner into it to free it up.
also check for vacuum leaks at all hoses and connections
