Is the Fuel pump controller necessary for WRX swap?

Homemade WRX · 05-01-2003, 12:18 PM

Hi, I am going to be swapping a 02 WRX engine into a 94L and am not sure if my wiring harness hass the fuel pump controller. I need to know if it is necessary to run the car, if not what are the side effects? could someone also show me a pic of one so that i can be sure whether or not I have one?
Thanks, Micah

yes the 94 is too small

Aspen · 05-01-2003, 01:16 PM

no not necessary, it will run without it.

side effects: might run rich in the lower ranges.

Homemade WRX · 05-03-2003, 11:00 AM

could a rrfpr control this? or maybe a S-AFC? and what do you mean too small? I don't know what this is in reference to.
thanks, Micah

The fuel pump controller is a small box, about the size of a deck of cards, physically located on the passenger side of the trunk behind the trunk liner, about 3" below the trunk lid.

I would highly recommend using the WRX fuel pump controller.

Without getting too technical, the computer won't be able to calculate and deliver the right amount of fuel your engine needs to run RIGHT!

Homemade WRX · 05-07-2003, 12:27 AM

how much does one cost? and could I see a picture of one? I may have it and don't know it.
Please help, Micah

Homemade WRX · 05-10-2003, 03:14 PM

does anyone have a picture of one? I may have it and may not know it. Please help!!

Aspen_2.5RS · 05-12-2003, 12:23 PM

I need this information as well. Basically what it would cost new and if anyone has one laying around from a wreck.

Guess I'll call the dealer soon.

I would highly recommend against buying directly from the dealer. It will be atleast 200% more than the cost at a yard. 4subaru will almost undoubtedly have it, but it will probably be priced higher than the other places.

Jon,

Thanks for the information. Yeah, I didn't plan on buying it from the dealership, I just wanted to find out what they charged so I could get an idea of what a reasonable cost would be for it.

Thanks again,

Cam

so does anyone have a picture of one or can give me a detailed discription or deminsions of the unit itself.
Thanks, Micah

stimpy · 05-13-2003, 04:30 PM

I'll gladly take a picture of it once I have mine in hand. However, since my donor car hasn't been located yet, I can't give you a picture.

Yes you need it...You will throw a check engine light if you don't have it...The controller talks to the ECU...I paid $120 for it from the local dealer...Its part of the WRX chassis harness and yes it bolts behind the passenger side trunk trim, in the hollow space...Its a little computer made by DENSO...

Soon2Bgreat · 05-19-2003, 10:47 PM

Just something else to think about. Someone with a v7 swap into a gc didn't use a fuel pump controller, it's also needed for that, and supposedly the car runs great, although there is a check engine light. I can't imagine it's something that an aftermarket ecu couldn't fix. Anyway, personally i'd get one, after all if your spending all the money on the swap, what's another 120 just to be sure and for peace of mind. Good luck.

Homemade WRX · 05-21-2003, 07:01 PM

yes I agree what's another 120 but that Denso tip may be helpful.
Thanks, Micah

What's another $120, ... the problem is that little things like that end up being alot of money in the end . That's the whole deal with doing a swap it always cost more than what you think.

I'd figure gas mileage might suffer a bit if you don't use it. .due to the fact that hard wired it would be at full blast all the time.

WRX rotors, calipers, pads, and brackets $200.00
AWD hubs $135.00
RS hood $185.94
RS front axles (pair) $90.00
RS rear axles, 05/2000+ (pair) $90.00
pedal assm. (with clutch master cyl.) $125.00
WRX wagon front control arms $130.00
Stock turbo-back exhaust $150.00

The drivetrain isn't even here yet so I'm sure more will be added...

Sunrise City Rider · 05-23-2003, 01:25 PM

Don't forget the $150 Rear 02 Sensor...

stimpy · 05-23-2003, 01:31 PM

That _should_ be included... ( I hope)

-Jon

Homemade WRX · 05-23-2003, 02:23 PM

dos anyone know of a sustitute system that can control the fuel? could a rrfpr or a S-AFC work?
Thanks, Micah

Imprezd · 05-23-2003, 02:44 PM
