Hello all,
This is my first post here. I hope someone can help with this trouble I am having. Please be patient while I bore you with the details leading up to where I am now......my wit's end.
This past summer I bought a 1988 2WD Subaru station wagon. It is a fuel injected non-turbo 1.8 with an automatic transmission. It is loaded with options (A/C, P.S., etc.). I bought it from relatives who had kept it well maintained, and were not experiencing any difficulty with it. Prior to me purchasing the car, they had just done lots of engine work to it....new head gaskets, timing belts, oil pump seals, water pump, tune up, fuel filter, etc. It was there daughters daily around town driver. The mileage is 114,000
I bought it and drove it 40 miles home with no troubles (and none expected). The next day I left for my 24 mile commute to work. After 8 miles or so, it started cutting out. I thought maybe my fuel gauge was wrong, and that maybe I was running out of gas. I pulled over, and by the time I came to a stop, the engine had died and would not restart. About 2 hours later it would start up. I headed back home, but it only ran for about a mile. I towed it the rest of the way. The local import mechanic didn't have time to work on the car but suggested 2 things. 1) A breather system update (rerouting of part of the breather system), and 2) A bad alternator....yeah, a bad alternator could cause it to cut out (he said).
About 6 hours later, I went home and updated the breather system. It started right up (probably would have anyway). I drove it the rest of the week with no problem. My wife then took it out of town shopping. After about 60 miles of highway and in town driving, it quit on her. I got there a few hours later. It would start and run just long enough to get it on the trailer. I tried isolating the alternator, but that did nothing.
By the next day, it would start and run fine. I took it to another shop for diagnosis. They had it for a couple of weeks. They scanned it and drove it a lot, and could not find any problem. Finally they called and said just drive it......call if it breaks down again.
It ran for 2 more days and then shut down one morning after about 3 miles of driving. This time I had some tools with me. I checked for spark.....It had spark. I pulled off the fuel line from the filter.....fuel would come out. I have no idea if it was enough pressure. I then towed it home.
A couple people suggested that the fuel cap may not be venting properly. I bought a new one and went home. First, I verified that it would still not start....it wouldn't. Second, I loosened the old fuel cap. It started right up. I tightened the old fuel cap back up and went for a drive. A couple of miles down the road it quit. I pulled the old cap off and put the new one on. It wouldn't start....ugh. I loosened it. It would not start.
Since this time, I have not been willing to leave the house with it. It will start up in the driveway and run just fine. I have idled it in the driveway for at least 20 minutes with no troubles.
The problem has happened after a couple miles, and after several miles. It has happened on a full fuel tank, and on a partial tank.
PLEASE help. I want to drive it or sell it, but either way, it needs to run. Could it be a weak fuel pump or ??????? I have been careful to not just throw money at guesses. I don't mind spending money on it, I just want good direction of which way to spend it. I hope to find something conclusive, so I am confident driving it.
Thanks very much for your time,
Michael Spears
