Something that we couldn't determine today. maybe bad fuel pump, may be something else electrical. It is fine at first, then the f/p drops off at 4K. to 20psi. and goes way lean. Scott has the graphs, I'll get him to post em. I have had too many problems with my fuel pressure ever since changing the pump. I can't afford to keep trying to fix what the hell is wrong with this p.o.s. car.

what pump did you put in?

It has a SVT Focus pump that was correctly installed, but there was a fuel delivery problem after the install. It looks like someone put a jack under the tank and jacked the car up bending the tank right at the fuel sump. The bend was fixed and the pump reinstalled and the car ran fine. I runs fine until you accelerate hard, then the fuel pressure goes up like it is suppose to, but at about 3500 the fuel pressure drops off to about 25 psi at 4000 rpm and the car leans out badly. We think it might be a bad fuel pump.

Have you guys checked the fuel pressure rail sensor? That was the first thing that went out on our focus. Then the pump went out

Lee we got a code: "Fuel pressure sensor error" right after the install and Richard bought a new one. When we made the second dyno run I watched the fuel pressure drop off from 40 psi to 25 psi and the "service engine soon" light came on. Doug was allready hooked up to the car and he said it was the same code so we swapped out the old FPS for the new one, but the fuel pressure dropped off and the car went lean again.

The fuel pump hose and clamps inside the tank need to be checked for leaks. It sound like he has fuel bleeding off when it gets to a certain pressure.

I'm assuming the fuel filter has been replaced recently, right? If not, that's the first thing he needs to do. Lee and I just experienced the same problem tonight on a new-edge Cobra with the fuel dropping off eraticly above 3500rpm.

Not the first time we've heard of a SVT Focus fuel pump having problems.

Just when I was starting to forget. You remind me
