alright as if the halfshaft wasnt enough, today about an hour ago, my friendly fuel pump decided to die, as if it wasnt a such a bad time i wouldnt be upset, i had to call and reschedule a job interveiw...Lucky me. Anyways im gonna need to know an easy way to do this, with out dropping the tank if its at all possible. Im thinkin cut a hole and weld it back to gether, or hell just silicone it? id like to know if anyone else has changed a fuel pump on a 1 gen. Only because i need to get this fixed, cheap and fast. So i can sell it. And the only reason im selling it is because im buying rabs pony...the modded one he put on the board. You must remember. Anyways the sooner the better.

Fuel pump is easier then the half shaft.

two push button clips hold the rear bench cushion.

screw driver to remove the plate :

NOTE: BE VERY careful, dont bend the metal fuel lines going to the sending unit.

You may need to use a screw driver and a hammer to move the locking ring.

the pump plugs in and sits in the sending unit harness just like the factory one.

Replace the fuel sock and get a gas tank gasket from ford. The aftermarket ones never seem to seal right.

alright, i seem to have run into a problem. On my 1989 LX, there is no door. Im sure someone here knows a nice quick way to change this thing. And where is the pump exactly, is it above the tank, or inline?
I need some more help. And another thing, how long should this take. Im sure someone changed one? i have my interior stripped also, so if its accesible from the interior thatll help.

The fuel pump is right under the rear seat. Just take it off. The instructions given you above are great. Take off the seat bottom only. There you will see an aluminum cover. Remove the four screws and take that cover off and VOILA! There's your fuel pump. Well, at least that's where it is on my 1998.

...and I think it goes without saying, but I'll say it anyway. If you're a smoker, this would not be a good time to light up...

Hey Seth, ahh my bad, sorry just kinda assumed the rest of the world drives a 2G like mine. 1G scorts may be different in which case you would have to drop the tank. Really sorry man, I was just tired and ignorant. Ask some of the 1G guru's like Justin.

But for 2G (and ZX2) owners...my directions can be useful.

Turbo: my partner in forcedinduction-crime that always helps me with my mods smokes like a chimminy and it seems like every time we're working on the fuel system he's lit up like a Xmas tree with bad wiring. Ya know, I guess I'm just pretty lucky gas isn't flammable in its liquid state.

I'm reasonably sure that you can't go through the back seats on the 1st gen to get to the fuel pump. I think on my 1984 GT it was underneath the car right in front of the tank.

hehe yeah I'm fairly sure 1gens have to drop the tank. Justin just had to replace his because his side exit exhaust punched a whole in the fuel tank and the pump was going out.

Go over to www.alldata.com its $25 but you get ever tsb and instructions for removing repairing just about any thing on a car. I have a 98 zx2 and here is what it says to do, at the bottom is the Fuel Pressure Release guide.

I AM IN NO WAY BE RESPONSIBLE FOR ANY PROPERTY DAMAGE, PROPERTY DAMAGE, OR ANY THING ELSE YOU DO BY FOLLOWING THESE DIRECTIONS. :D

Disconnect the battery ground cable.
Perform the fuel pressure release procedure.
Remove the rear seat cushion assembly.
Disconnect the two fuel delivery module electrical connectors.
Remove the four fuel delivery module access cover screws and remove the fuel delivery module access cover.
Disconnect the fuel delivery module electrical connector for fuel tank pressure transducer.
Remove the fuel line clip and disconnect the fuel line.
Use Fuel Tank Locking Wrench to remove the fuel delivery module locking retainer ring.
INSTALLATION
To install, reverse the removal procedure. NOTE:
When the battery is disconnected and reconnected, some abnormal drive symptoms may occur while the vehicle relearns its adaptive strategy. The vehicle may need to be driven 16km (10 mi) or more to relearn the strategy.
Install a new fuel pump mounting gasket. Replace the fuel line clips if necessary.

Remove the schrader valve cap at the end of the fuel injection supply manifold, and attach Fuel Pressure Gauge. WARNING:
DO NOT SMOKE OR CARRY LIGHTED TOBACCO OR AN OPEN FLAME OF ANY TYPE WHEN WORKING ON OR NEAR ANY FUEL RELATED COMPONENT. HIGHLY FLAMMABLE MIXTURES ARE ALWAYS PRESENT AND MAY BE IGNITED, RESULTING IN POSSIBLE PERSONAL INJURY.
FUEL IN THE FUEL SYSTEM REMAINS UNDER HIGH PRESSURE EVEN WHEN THE ENGINE IS NOT RUNNING.
BEFORE REPAIRING OR DISCONNECTING ANY OF THE FUEL LINES OR FUEL SYSTEM COMPONENTS, THE FUEL SYSTEM PRESSURE MUST BE RELIEVED.
Open the manual valve on Fuel Pressure Gauge slowly to relieve fuel system pressure.
