Hi Subaru guys. I have had a 94 Legacy engine in my van for 4 years now with no problems. Recently as I was driving down the rod it just quit like I turned thje key off.
It restarted after about 3 tries and I drove home. This started to happen whenever and wherever. I changed the ignition switch as suggested by yahoo van subaru group.
My battery was at the end of usefulness so I bought a new battery. The van ran fine for about 3 weeks and same thing. I checked all the VW problem areas but all the +P points are good all the way to the ecu, same year as engine.
I notice that when I crank the motor, then let the key rest to the on position nothing happens and when I crank the motor, turn the key to the off position, just as I am twisting the key off the engine gives a slight rumble as if wanting to start.
It seems as thogh when I remove +P from the system while turning the key off something fires the ignition just once and burns one or two cylinders.
This happens every time. If I crank for several seconds and turn the key off I get a much more agressive rumble than if I crank for just a second or two.
Yesterday when it wouldnt start in the driveway I was prepared with a test light and body and engine ground were good and all the +P points at the ecu were hot.
At this point I am a bit lost and dont want to just start changing parts.
It seems I had an old vw 40 years ago that would not start when I cranked it and gave the same engine firing as I turned the key to off position. It turned out to be the coil.
However the Subaru motor seems to have more components to the firing system than the old 6 volt vw.
Any thoughts? I have visually checked, pulled , shaken the engine wiring and had no luck. Just sit for a few minutes and everything is working again.
