Fuel delivery problem HELP!
 
Hello,

I'm a noob, love the site!

I have a 2002 ZX5 Zetec with 170,000mi and I'm getting no fuel at all. I just bought the car in a non-running state. I put a new battery in it and it turns over just fine, but and when I turned the key on I couldn't hear the pump prime. I then got a wiring diagram and traced power all the way to the pump so I figured it was the pump. I dropped the tank, replaced the pump, and put it back together.

Now I can hear the pump prime up like it's supposed to...but I've still got no fuel delivery at all. I even disconnected the supply line from the tank to the filter....nothing coming out of the tank, no fuel flow, and I'm highly confused. I bought a code reader and there are no codes.

Has anyone else run into this problem, this is my first high mileage focus...FPDM gone bad? Fuel pressure regulator gone bad? Any help would be greatly appreciated. Thanks

Maybe fuel pump control module

welcome to the forum. maybe filter or as stated above the module.. if car sat for a period of time im wondering if somehow maybe a line is clogged up

Very unlikely the Fuel Pump Driver Module went bad.


Where did you disconnect from to test if fuel spewed out?

this is where he disconected according to his first post

I even disconnected the supply line from the tank to the filter....nothing coming out of the tank

The line is plugged IMO.

Run something like a coat hangar through it and se if it works then.

yes run a coat hanger through the line or take a air hose and blow through it its possible that its plugged

I disconnected behind the fuel filter because I wanted to isolate the tank and pump from the rest of the system to see if it was the pump or the body fuel lines or etc... The only thing left is that little 10" fuel supply line coming off if the fuel pump sending unit.

The gauge reads 1/4tank of fuel, and the pump runs so the car is telling it to supply fuel... But nothing spews out. I don't want to drop the tank again for fear of a weld nut breaking or the 170,000mile old straps, so maybe I will cut the access door to access the sending unit and make life a little easier.

Thanks for the suggestions to far, let me know if anything else comes to mind

When you got a pump, did you get a whole pump assembly or just the pump? If you just got a pump, it might be that the pump is disconnected from the sump, and therefore isn't pumping anything.

I agree with Iminhell that the fuel pump control module is still good- otherwise the pump wouldn't come on at all.

No matter what, if you're not getting fuel that close to the tank, then you're going to have to drop the tank again. You might have a pinched line, or disconnected pump in the tank, or just a bad pump. Apparently your problem is right there, so we're not going to be much help.

Ya, it sucks, but we've all been there and done that on some repair at some point.

I just bought the pump.
