Customer Question
I have a 2002...

I have a 2002 Ford Focus zetec motor quad cam . It will not stay running. It’s giving a code po171 lean. I’ve had new fuel pump new fuel filter new plugs and wires new coil pack new throttle position sensor injectors cleaned PCs valve and hose replaced . It will start but runs rough and when I try to drive it it stalls out. I checked for vacuum leaks and replaced a couple bad hoses now I’m stuck and tired of throwing parts in and it not working . Any help would be appreciated

Mechanic's Assistant: Are you certain it's the fuel pressure sensor that's in need of attention? What about the fuel rail? Have you checked it yet?

No how can they be checked to see if it’s bad?

Mechanic's Assistant: Are you fixing your Focus yourself? What have you tried so far?

I’ve had about5 people work on it

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Thats all for now

If there is a P0171 lean code and the engine will not remain running, this is likely an air/vacuum leak provided there is no internal engine damage.

In addition, the mass air flow sensor could be faulty and or the air intake snorkle could be cracked/ripped too causing this condition.

I will start checking those two things. I know a compression test was done and it was good.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey

I would (and have) recommend your site to others I was quite satisfied with the quality of the information received, the professional with whom I interacted, and the quick response time. Thanks, and be sure that I'll be back whenever I need a question answered in a hurry.
