So I checked recently and my car wasn't getting any fuel in the fuel rail. Its barely any. Like after couple of cranks little comes out. Not enough for injectors to spray it in.

I took the old pump out and found out my AWD Eclipse GSX has FWD tank. So disconnecting the pressure line it was stuck like it'll break so I did some cutting just to bring the filter up enough to change it.

Now problem is I tested the old pump with 9v battery. It spins just like the new one. Will it be worthless to switch it? I'd rather not waste the 80 if the car will do the same thing after I change it. Old pump was making the same spinning noise connecting 9v battery.

What else could be the issue? Should I change it anyway and see ?

Check / change your strainer and filter. Disconnect the fuel lines and make sure they are clear. If the pump pumps, it sounds like something's clogged up.
I'm not familiar with the differences between the fwd and awd tanks so cant say if that has anything to do with it.
 
A 9v won't tell you anything between the two pumps, they have a hard enough time with 12+ volts.

You need to ensure there are not obstructions in the line (kinks, filter and strainer sock clogged, etc), then address the pump and it's wiring. I would do a rewire so the pump gets adequate voltage and a good, solid ground. See what you get after this.

Is there any guide to rewiring it?

I was thinking the same thing.

I don't see how you could possibly have an AWD with a FWD tank. AWD tanks have clearance for the drive shaft, a FWD tank would be in the way


AWD ...............................................................................................................FWD

As above, a fwd tank isnt a saddle design so your driveshaft would not fit under it. Also a 9v battery might spin the pump impeller but you wont get any appreciable flow as it cant supply enough juice.

do you have the ability to toggle fuel pump while checking voltage at its connector with a multimeter?

lastly, that thread title was really confusing

Nobody here can figure out how you determined you can't get any fuel through the rail or how you think you have a mismatched fuel tank....did you forget to check and see if your filter was clogged or needed changed? Don't just buy parts if you're worried about 80 dollars without properly diagnosing your issue. Clean up your terminology, and form a technically sound question. People may be more relaxed on new members due to how dry the forums are in 2019, but it will only help YOU in the long run to get a real answer to your problem(s). Most members will see bad sentence structure and obviously answered questions as an instant pass rather than to comment. Good luck

To me, it seems like english is his 2nd language.
 
So thanks for the all the replies. I'm sorry, it was very difficult to explain all these stuff. I'm new to this so sorry in advance for not doing a better job at writing my problems.

This is what I meant. I might still be wrong so please do clarify. The first pic is how my housing is. maybe saying fwd tank was the word way of putting it. If I'm not wrong. The 2nd pic is how the housing should be and theres also another extra line running from the housing there which my housing dosent have

I have a new fuel pump on but it seems like power isnt getting to my pump when I the key on. I made the mistake or just changing parts without doing a full diagnose. So my question is. My fuel pump seems like it's not getting power. I disconnected the rail and saw no fuel was flowing. After multiple cranks fuel starts pouring out but it's not a lot. I was wondering if I could use direct power from the battery to turn the fuel pump on. Is that possible if yes could someone explain it to me in details. Thanks in advance.
 
I just want you to make sure, when you replaced the pump, did you have to solder the power/ground cables to it or did you use the already existing OEM plug? I feel I need to ask this, because I once had a no start issue and it turned out I mixed up both wires on the pump so it ran backwards each time I cranked. Sometimes it's silly things like these...

Good catch but I made sure black went with black and blue with blue. Thars how it goes right ? Xd. I'll double check it though.
 
the 1g AWD tank has the bolt on top

so just to be sure your car is a 2g, what is the year of your car?

on a 2g AWD there are 2 assemblies, the upper one is this picture (drivers side) is for the fuel gauge,
the lower one (passenger side) is for the fuel pump

Mine is the first pic for the thr 1g tank. My car is 1995 eclipse gsx awd turbo 2.0.


I'm having fuel issues. It dosent prime when I turn the key on to acc. Once u crank that's when therrs slight sound of pressure back in the tank but it dosent come to the rail. Is it possible that my battery dosent have enough juice to supply the 12v? I have . A bad battery. Was boosting it from my other car.

the black one is for the fuel pump

blue is for engine speed (RPM)
brown is for ignition timing adjustment
 
on 2g cars there are 2 access panels under the rear seat

FWD has one on the passenger side and one in the middle
AWD has one on the passenger side and one on the drives side

FWD have a metal fuel tank
AWD have a plastic fuel tank

i don't see how it would be possible to use a 1g tank on a 2g.
This might be a dumb question but have you actually looked under the car and made sure it has a drive shaft?
Maybe the previous owner (if there is one) converted it to FWD or something stupid like that.

Thats really the only way i can think of to have the bolt on style of top on the fuel pump assembly.

If you want to post up a few pictures we can probably figure it out. other than that i don't know what else to tell ya
