Hello,
I have been tinkering with a Barn-find 1998 ZX-2 for the last year. It sat for 10 years and will become my girlfriend's son's first car. It was his great-grandmother's last car.

I determined that the fuel pump was bad, and expensive. I found a barely-used pump from a later car and now the car runs. It does not drive yet. Concerned family members cut the throttle cable...

My question is about the 2 extra connectors on my earlier pump. I get fuel and the gauge works, so one 6-wire plug works.

New to ZX-2s but not new to Fords.

The actual fuel pump only uses two wires, so can't you just change it, without altering the other wiring?

Could you post a picture or two of what your setup is?

I buy cheap ebay or Rockauto fuel pumps, they seem to last forever. What usually kills them is sitting in ten year old rancid gasoline.

Always a good idea to clean out the tank whenever you replace a fuel pump, otherwise whatever took out the last pump will likely take out the new pump, then you're replacing fuel pumps on a yearly basis.

Are you talking about wires to the pump itself, or the wires to the fuel tank pressure sensor?

The filter sock is supposed to keep all that junk out of the pump.
I did have a jammed pump once from the sock falling off, no doubt I didn't put it on properly in the first place. I was able to un-jam the pump (on the side of the road), put the sock back on and carry on.

Good advice on the tank cleaning. Just as soon as the car proves itself. Then new tires.
The old sock was ripped apart and full of "mud".

Huh, I'm pretty sure my car is an early 98 and it only has the 6 pin connector for the fuel pump, sending unit, etc. and a separate connector that does not go to the fuel pump at all, but rather to a separate fuel tank pressure sensor.

Were they plugged into anything when you pulled the old pump? Might be that someone already threw a fuel pump at this car and used some aftermarket pump.

All three plugs were connected. I was the first person to access the fuel pump.

I understand what you're asking now, perhaps my car is a late 98 model after all. Though I'm not sure what the 3rd 3 pin connector is, unless that's an integrated fuel tank pressure sensor.

Assuming everything on the pump is the same, which I would be surprised if it was, and If the pins are the same on the car harness side, you would just need a new connector (or snip off a pigtail at the junkyard from a later car and extract the pins of the cut wires), extract the pins on the car side of the harness, and put the pins into your new 6 pin connector, making sure each one goes to the right harness.

This is the route I would go being careful not to bend any of the pins, this would require no cutting of the car harness.

It is also possible an adapter exists (or I suppose one could be made pretty easily) to go from the 4 pin and 2 pin connector to a single 6 pin connector.

That's a whole fuel pump module. It's not difficult to get it apart to find the actual pump inside to change:

Which, I believe, should look like this, numerous examples available for $8 to $20 on ebay:

I also see Rockauto has a whole assembly for $55, Ultrapower 2630322 (1998 Escort,one year only!), which looks like it has the three connectors:

I think he already has a new (used) fuel pump, but got it out of a car that has a single 6 pin connector instead of one with a 4 pin, 2 pin, and 3 pin connector. Looking at that picture from RockAuto that almost looks like the existing connector has spots for 6 pins? Also, if the new fuel pump does not have a fuel tank pressure sensor (again, assuming that's what the 3 pin connector is, and that it is integrated), you will have an open circuit for the FTPS. This may make the evap system not work correctly. You would need to either replace the whole tank with the newer style (assuming it would still work), or get the proper fuel pump.

I'm guessing he's looking to get it working to the point where it will be easy to tell if it is worth putting the money into it for new parts.

The fuel pump itself only has two wires.
I think there may be some confusion between the entire fuel pump assembly and the fuel pump itself.

I can mix and match between the 2 pumps I have. Using the newer pump (2 wires) with the original housing and plugs.
