The 1999 Ford Countour SE, V6, 2.5 L car would stall and turn off when I was driving, unless I would put my foot on the accelerator. The check engine
light was on. This problem became more pronounced over time and seemed to have worsened when the car would be sitting cold, too long. I took it to Ford mechanic and they replaced the IMRC and o2 sensors replaced (no reading from O2 sensors). They also said that there was a vacuum leak in the lower intake manifold + hose, since the O2 sensors were saying that the engine was running lean in Bank 2. And that it would need replacement (parts were not available)
Yesterday, the car would not start, when i tried to restart it to return home from a friend's, after having had driven it 20 miles only 10 minutes before. The engine would turn but it would not catch. I had fuel in the car. I had even let the car sit for a day, in case of water in the tank. But So it was towed to the dealership. Apparently, they said that the fuel pump is not working and needs replacement. No electrical output from the part.
It was strange, when I was driving the car, there was a moment, when I felt like I couldn't push on the brakes
. This was the point when the check engine light came on again.
Does it sound like the fuel pump. And if so...should i get the full fuel pump assembly?
And does a bad fuel pump/fuel pump assmbly, have anything to do with the vacuum leak in the lower intake manifold which was causing a reading to the O2 sensors to indicate, "lean conditions in bank 1 and 2"? And as for the IMRC, it must have something to do with vacuum leak in the the lower intake manifold, no?
