Subaru RX Problems


Recommended Posts

Maybe rust in your tank, tap the fuel filter on the ground and look for rust. Those "jumper wires" are the fuses, they are called fusible links.

 

I'd crimp off the line that goes from the fuel tank to the pump under the car with some vise grips, remove the line from the pump and release the vise grips. Drain it into a coffee can with some sort of paint strainer on it and look for rust or anything else that could be getting clogged in the lines or the tank. If yo do find something, either replace the tank from any fuel injected EA82 car (2wd, 4wd, manual, auto, it doesn't matter) or have it professionally cleaned out.

I will check the tank too.

 

But today i found the real problem.

The connection on the fuelpump is loose.

And i have to hold it tight together to get the pump going.

 

Tomorrow i'm doing a new connection and hopes for better function.

Was no rust in the fuelfilter when i checked it today.

 

Hopefully i can drive the car tomorrow :P

 

My Grandpa will be really happy now.

He bought this car from the Factory 1987

and sold it to my cousins who drove rally with it :)

Or they thought they where :P

 

It went from mint condition to crappy in 2 years :(

But i think i can get it back up again.

the relay is under the steering wheel area by the computer with other relays for headlights, defrost, ignition, etc.....

 

I had to swap fuel tanks due to lagre amount of crud in tank, but now is good

 

I used to have an '87 RX 3door, and sold it about a year later

now I drive the '86 gl-10 turbo wagon with ea81 :banana:

 

ask any questions you may have :D

Thanks for the update.

 

The pump you have sounds like a pump for fuel injection?

I did not look it up to see.

 

I mean to say, it's not the volume so much as it is the pressure

it delivers the fuel at.

 

The factory pump when operating properly is very well

suited for the engine in stock form.

So you dont think i should use the Walbro pump instead ?

 

Because here in sweden its almost impossible to find a used pump

to this car.

And a new one costs 3 times more than a Walbro.

 

 

The thing with my pump is when its out in the cold its just

working when i hit it.

But inside it works all the time.

 

And its not the connections that is the problems because i have changed them now.

Sir, if it is indeed meant for fuel injection systems

yes use it (see below)

Your old pump may have had a fuel damper

connected directly in line with it.

Some people leave it some don't.

Well this is an entirely different situation.

 

My previous statement was based on the fact that you said

"But today i found the real problem.

fuel pump pressures and flow

carb 2.6 - 3.3 psi 38L / 10 gmp

mpfi 61 - 71 psi max relief valve setting, 95L / 25.1 gpm @ 43.4 psi

 

the pressure regulator adjusts the fuel pressure to 36.3 psi compared to the intake manifold pressure

 

pressure engine at idle 26 - 30 psi

pressure with pump on and engine off 37 psi

pressure with pump off and engine off 33 psi

 

'85 fsm

 

spfi is approx. 20 psi
