#139 of 156 1996 Subaru legacy 2.2L having trouble starting and staying started
Oct 16, 2011 (4:24 pm)
About a month ago my Subaru would sputter when taking off, until eventually it went out. My son and I put in a new fuel filter and fuel pump and it ran great for about two weeks. Then it just went out on my son while he was driving. Would turn over but wouldn't start, as if it wasn't getting any gas. Went to tow it and it started right up after sitting for about a week??? Today... Didn't start! Does anyone know if this can be electrical or a injector problem? Battery and terminals are fine. Any help would be much appreciated!

When is it not starting? In other words, do you notice this when the engine is cold (such as sitting over night), or warm, or does it matter.... ?

It does it in warm or cold weather. First time was on the highway,second about 2 miles after leaving home in war
m weather. When it started the other night,it had been sitting for about 5 days, the next day... Nothing.

Okay, have you had any issues with it while it is running? Any engine stammering, etc?
It almost sounds to me like there is a relay that is shutting down the fuel system on it, which means the relay is either going bad or it is getting poor feedback from one of the connected sensors. That, too, could either be a sensor, or a poor wiring connection, but those things work on resistance. So, if it is within spec at the time the car is doing the system check, you're up and running until you shut it off. If not, you're not going anywhere.
When the problem happens, do you hear the fuel pump priming in the rear of the car? In other words, when you put the key in the ignition, turn it to "on" and wait a few seconds. What sounds do you hear?

Before we put the fuel pump in we did have problems, it sputtered at take off. After the fuel pump, no sputter but flat out dies and stays dead. Just went and tried starting it and it did start after sitting again for a few days. And it stood running. Heard the starter make a humming noise before starting. Tried starting it again and nothing.

Okay, that if you were not attempting to start, that was the fuel pump making that humming sound, so it's not the relay I was visualizing.
It sounds like an electrical/sensor issue. That's going to mean diagnostics. Simple things to check... are you getting any current out of the fuel injectors when it will not start? How about spark? If it isn't even trying to fire, one of those things has to be missing. After you determine that, the "why" becomes the fun part.

I will try look into the current but can't really get busy on it until this weekend due to getting home after dark every day.I appreciate your help in narrowing it down and will post when I work on it this weekend. Thanks again for your help!
#147 of 156 Trouble starting the engine.
Nov 06, 2011 (10:03 am)
I have a 1996 Legacy Brighton 2.2 L with 100,000k on it. I recently had the timing belt, water pump, thermostat, and belts changed. A couple of weeks after this, the car wouldn't start. I tried for some time and finally it started. The check engine light came on and I went to the mechanic who checked the engine code and it stated "Cam Shaft sensor circuit fault" . He changed the camshaft sensor to the new one with the yellow dot on it because his code reader said that there had been problems with the old camshaft sensor. The problem went away for a week and then again the car would not start after a short trip. I left it and half hour later, tried and it started. I then checked the connector that looked a little rough and went to a wrecker and got a new connector with a long length of wire. I spliced the new connector on, soldering the wires and used heat shrink tubing to repair the insulation. Again the problem went away and then a couple of weeks later it again failed to start after a short trip, engine cranks at a good speed but no firing. I waited for a half an hour and it started and seems to run fine now. Has anybody had this intermittent starting problem with the Subaru engines?

Yep; I had that problem for years. Initially it drove me nuts, then it was just something I became used to encountering. Mine was a 1996 (Outback) with a 2.5L engine. I could crank it dead and it wouldn't start, but if I cranked it and nothing, then I would wait 5-10 minutes and try again until eventually it would fire up as if nothing had ever been wrong. The longest it ever took was about 50 minutes, but it sure was annoying. It only ever happened when I tried to start the car within about an hour (or so) of last using it - basically, if the engine was still warm, there was risk of no-start. Again - completely random. Sometimes it would work perfectly for weeks, sometimes it would happen several times within a week (or even multiple times a day).
After about four years of that, I had a problem with the knock sensor. I replaced the knock, cam, and crank sensors simultaneously, and not only did that solve my immediate problem, but it had the happy coincidence of eliminating the no-start issue as well.
Good luck.... !
