RHD JDM Intermittent Stall
Posted: Wed Oct 01, 2008 4:21 am
Hello All,
My first post here...have enjoyed reading others for a while. I own a JDM RHD 1991 Legacy GT with the EJ20G and an automatic transmission.
Great car, love it, perfect for the winter's here in Calgary..... However, it has develepoded an issue that has made it unsafe to drive. It began stalling at random times and I can't figure out what is causing this.
It stalls when driving normally, when the foot comes off the accelerator while driving, while sitting in the driveway idling, etc. It usually starts right away again, but sometimes it takes some coaxing and then it runs like new (until it happens again), one thing I have noted is that it has not stalled from cold.
With regards to frequency, you can be sure it will happen once every 10 minutes of driving (though lately I haven't driven it a lot except to test it or take it to a technician)
I initially took the car to a Subaru "specialist" shp in town and they replaced:
1. Crank sensor
2. Cam sensor
3. Atmospheric Pressure Sensor (I had to order this from a wrecker in Australia)
Three times they said "It's fixed!", I picked it up, only to have it stall on the way home. Extremely disappointing and I will not be taking it back there.
The only code they ever said it had was for the Atmospheric Pressure Sensor....and changing this did not fix the problem.
I don't know a lot about diagnostics but I have looked for the black flash code wires (as discussed in other posts) and cant find them.....I think it has an OBD port...is this possible?
At any rate, I was wondering if you guys had any ideas. So far, I have changed the fuel filter (no fix) and I think I will change the fuel pump next so that I can rule out "air" and "fuel" and focus on spark.
I removed the stock pump and turns out it is a JECS A42-646055 which was only used on the early Legacy's with the EJ20 and the 92-00 WRX (which wasn't available in North America I understand). So if anyone has a source for this or another solution, let me know (I tried the one from the 2.2T and found that it has the wrong base to it).
The only other thing I can suggest is that there is a red wire heading into the fuse box under the dash that a technician tapped ( a couple years ago) to run the relay for the daytime running light system ... it is a small wire and I have removed the tap and there is some exposed wire. I will try and describe it more clearly ASAP.
So that's it.....if anyone knows a good technician in Calgary I could take it to, or how to get the correct (or next best) fuel pump, or any other suggestions, I would greatly appreciate it.
Thanks in advance.
Matt
