Ford Focus 2000 Problem Solution

That such friends, I have a problem, to start I have a Ford Focus sedan Motor Spi 2.0 Automatic transmission, the problem is that after a certain time the car is emphasized to maroon and turns off as if fuel fuel, after it goes out I started again and as if nothing but advanced the same of distance and re -pulls again and again turns off, and so it happens repeatedly, and so it happens repeatedly, and so it happens again, and so it happens again, and so it is repeated. Nothing, already check injectors and these are perfect, check gasoline filter and it is clean, since it changes it recently, it is placed Scanner and does not appear fault codes, the pressure is monitored and walks in 65 psi and is correct and when it begins This discomfort causes me and if this fuel supply system brings a special attachment to control the pressure or pump, and if it works. I will be very grateful to your aid that can provide me.

Solution at the bottom

The bombs are calibrated for a certain precion can lower but never upload, the check does not turn on so it discards the electronic system and the gearbox because it should run to fail in both senses, it could That is your problem if it helps you, it opened to check all hoses and fuel pump

That such a friend I have the same problem as you alone that in a 2002 Mondeo as soon as I find my problem I give you the news of how to solve it but for the moment I do not buy a bomb or replace

In such a case it can be anything like the relay that sends the power supply to the pump this failure is not recorded in the memory of the ECU, or the fuel pressure regulator.

It is discarding things to me that you have a motor fails and it turns out that the foller lid of the gasoline tank does not seal or the power maintenance relay that feeds the fuel pump relay or there is an air input to the injection system as Kikec comments good luck with the problem Macplus: Woohoo :.

SOLUTION:

As I ticked a few days ago, I had the problem that it advanced certain kilometers and began to pull and went out, well, what I had that day was to check everything that I mentioned above, well, it monitored again but this time with the car on the way and took a few times until the fault appeared again, the pressure of 65 psi to 0 psi to 0 Check where the pump was located, lifted the rear seat thinking that I had a lid to take out the pump and what caught my attention is that it brought a black box and proceeded to investigate that it was that, before doing something else, this box is called the controller (or driver) module of the fuel pump, so it also investigates the electronic diagrams of the connection to the pump, assuming that this was the fault, it connects a multimeter for a multimeter, it connects a multimeter to connect a multimeter for a multimeter, connect Check if the connector did not have failures, uncovered the module and everything seemed to indicate that it was fine, connect the multimeter and put the manometyro again, I turned a few times to the car until the fault appeared, and the pressure was repeated again. To the low pressure that existed, and with this I deduced that it was the bomb definitely, the tank came down, for my bad fortune, and check the pump outside in a bottle with fuel and put it to work until the fault appeared, what the pump had is that it works well but for the working time it was already dirty and covered with the oxide of the tank and towards which the fuel was Remove all the success and oxide, which if I had to buy the pump spare, and from there it has not failed again.

And as Kikemec mention the check Engine since it does not stop in this type of failures, just place the scan to see some pending code and monitor the pressure and automatic transmission, so having this as a basis I went straight to the fuel system.

I hope the solution I found for my problem and greetings to everyone and thanks for your comments.
