I AM IN DIRE NEED OF ASSIASSTANCE.... I cant [:)][:)][:)][:)] this project up anymore, or i have to send the car to the junk card, and ive put so much time, money, and my child hood into it.



So I recently inheritied a 2001 Zx3 2.0 DOHC which is my child hood car because my mom passed last april, and ive been trying to fix it up so its cherry. So far, ive spent over 1500$ in the Engine, and some suspension. And now the focus curse has reared its ugly head again, and now my fuel pump took a shit (im pretty sure).

After siphoning a full tank of gas (and getting plenty of gas in my mouth) i tried to replace my bad pump with an aftermarket O'rielys, autozone, and car quest pump. All of them sat in my assembly cruckid, and did not seat all the way properly. So I returned them, and went onto my next option.. No money lost there,

So, I went to a JY and ripped out a 2003 Focus LX 2.0 SEFI Fuel pump, assembly, and the driver module. After replacing the Fuel pump the first time with aftermarket ones and it not working, I turned here. Bad idea, I ended up spending 70$ for those 3 parts, and after replacing the fuel pump, putting the tank back up into the car, i primed the JY pump, and it started! but it was idling so rough, and only stayed alive for maybe 10 seconds? Dead after that.... Lost some there,

Next, EBAY! 30$ brand new pump, hope it works, keep reading lol

(new ebay on left, old on right)

Now im onto my next option, which i have already put into the car, but before I try to start the car, i am going to test every connection with my multimeter, I just need to know what certain wires are suppost to be, what volt. And im kinda concerned about a few parts, and also have no idea what others are, which is why im here. I took in-depth pictures of everything, so you can guys can tell me what i'm doing wrong..


My inhertia switch... has it tripped? Should the wires both be 12v power sources?

the cords look in good condition



Onto my Fuel Pump Driver Module. (The OEM one that came with my ZX3. Not the JY Donor car)
Will this work with my Ebay fuel pump??
I REALLY NEED THE VOLT READINGS FOR WHAT EACH WIRE SHOULD BE COMING OUT OF THE CONNECTORS..

Do I need to sand this surface down? (for a better ground?)

Are theses wires correct?


Six wires, Left to right,
Green/Orange (12v Power?), Green/Orange (12v Power?), Solid Black (Ground), Solid Black (ground), Black/White stripe (Whats this?), Green/black (Another ground)?
What is the voltage they should read with the key "On" and the also with the engine cranking?

Does this all look correct so far?






Is this going to screw me??


Do they match up?

What is this?


I had to swtich the fuel sending unit from my original assembly to the donor assembly because the donor unit did not work (Im using the donor assembly, no donor pump/sending unit)


spliced right?

my old spliced, i re-did it and cleaned the assembly up



what is this?

I can not tell you what wires need to check but I will ask this, Did you check to make sure the relay is working right by swaping it out with different relay in the fuse block?

No.... I personally don't trust aftermarket pumps. Motorcraft pumps have much longer lifetimes which makes that more expensive option on the front end much cheaper in the long run.

To test the inertia switch, just push the button down. If you think the switch might be the problem, remove the kick panel, unplug the switch, and bypass the the switch by bridging the two pins in the plug with a paperclip. Do not leave it like that under any circumstances. If the pump will not run with this switch plugged in, replace the switch before driving. Bridging the pins is only for testing purposes or emergencies.

I assume you changed the fuel filter and purchased one with the fuel pump. That will be necessary to return it. I saw the pic of it. Warranty information like that comes from experience since most people don't read that a filter must be purchased and installed at the same time as the pump. You should also replace the sock filter over the pickup. All the different things are why I now purchase a whole fuel pump assembly. Check prices at places like Rock Auto if you don't want to get one at a local parts store. It is much cheaper to buy complete assemblies at online parts stores.

If you are not getting 12v power to the fuel pump module with the key on, stop. You have problems elsewhere.

so, if i bought a new fuel filter with the first jy pump, i have to put an entirly new fuel filter with the ebay fuel pump ? or its okay since i recently bought this one. I'm also gonna put fuel threw it before i accually try to filter with it.

i really cant spend anymore money on this is why im doing it myself, i went to buy a new relay for it, and there 25$.. i only want to spend more money if i know itll fix,
theres no warranitys on electrical items so i cant return the relay :/

I wouldn't feel stupid. The reason he originally suggested that you swap the relay with another relay is because it is extremely rare that those go out. I've been working on vehicles for a very long time, and I can only recall a very few times when relays went bad. Timed relays- yes, but not simple switch relays. Therefore the best way to test before you buy is to simply swap the relay with another relay which you can test easily like a headlight relay. I would be more suspect of the wiring to the relay than the relay itself.

Glad it worked out for ya.

Glad it you found it out.
I was in the same boat with my truck a wile back. I put a brand new relay in it before I replaced the fuel pump. (pump was not working and then started making a horrible noise) but right before that I had been having issue and then I had them after I installed the new pump.
Well 90% of my Issues were due to the brand new relay not working out of the box just like it should have. I over looked it the whole time.
