Thanks danzik, Funny thing is the last time it died and I checked under the hood I noticed that the fuel injector connector was dangling perilously close to the accessory belts. The little plastic "shield" was missing that prevents things from contacting the moving belts. I unplugged it and tucked it in with the other wiring in that location and reconnected it and the car has been running fine since! The only odd thing is that even though I have NO warning lights lit on the dash when I do a read memory trouble code 14 comes up and I cannot clear the memory by the FSM procedure. My kid hasn't been left stranded again so it's just "keep your fingers crossed and call me if you need a ride".

Thanks for the reply. I didn't think the O2 sensor had anything to do with it but figured I'd throw it out there. Here's a brief update. The CEL is not on but the code remains in memory and will not clear by the FSM procedure. The car cold started just fine yesterday and ran for a 36 mi round trip with a hot start in the middle. When I got home the code (displayed in Read Memory mode only) still refused to clear. I guess we'll just keep running it and hoping that nobody gets left stranded anywhere. The alternator was recently replaced with a used one that's putting out 18V (the old one caused the dash to look like a Christmas tree).

Hi all. I know this thread is almost a year old but it is the first one I've found that is describing anything close to my problem. You probably guessed from my name that I'm new to Subaru. I've done tons of reading so this might sound like I know more than I really do. I've had a '91 Loyale SPFI for almost 2 years and recently ran into some issues. I'm the second owner and bought it with only 68k on the odo. Has only about 75K now. Tried my hand at a timing belt and re-gasketing job last summer for the first time on any car and still had leaking problems so I had a local garage with a former Sub tech redo the HG's and cam covers, leaks stopped. Anyway, recently got a CEL, read the codes and it was the O2 sensor. I had a new Denso single wire one (p/n 234-1000) hanging around that appeared very similar with correct threads so I put it in. CEL gone within 5 min of first drive. Probably unrelated but not sure (which is why I gave the history above), the car was driving along fine and just quit on my son and wouldn't restart. Left it roadside for the night, stopped by in the morning and it started right up! Got to within 2 miles of home and it quit again and wouldn't restart. Came back about an hour later to tow it home and it started again and drove home. Read codes and now have code 14 - Fuel Injector Abnormal Output in the read memory mode (white connectors) but nothing in D-check mode! The FSM says that this indicates a problem with the harness for the component but not the component (in this case the injector). I unplugged the ECU and tested the continuity from connector terminals 43 and 48 (injector + and injector -) to the plug at the injector and it tested OK but the memory won't clear by the FSM procedure! I don't trust the car but my son has no choice, he need to get to work. Now the $64,000 question, is it possible that the non-Subaru O2 sensor is providing weird values to the ECU so it is cutting off the fuel to prevent engine damage? Why can't I clear this code and more importantly, can I trust the car? Oh yeah, new fuel pump last year also (another long story). Thanks for reading my saga and for any help anybody can offer.
