cwerst Posted November 11, 2016 Share Posted November 11, 2016 Hello, My fiancee has a 2011 Legacy 2.5i and she as been having issues with what I am assuming is the electrical system. About two months ago she was having issues with it not wanting to start after having been sitting for 8 hours while she was at work. We took it to the local dealer and they inspected and said it was the battery. So I bought a new battery and put it in and things were better for a time. The starting issues have returned and today she was driving, luckily just waiting in a turing lane, and her car died. She said all the lights lit up and then it just died. No sputtering or anything it simply died. After being pushed out of the way and waiting a couple minutes her car started and made it the 6 miles back to our place from in town. I have done some research about the starting issue and what I've read suggests that the engine isn't getting fuel to it. But this dying in the middle of the road thing has me lost. I'm not the most knowledgeable guy especially with Subaru's. Any tips or solutions to her issues would be very much appreciated. Thank you, C.

wtdash Posted November 11, 2016 Share Posted November 11, 2016 (edited) HI and Welcome, If the dealer didn't test the Alternator, don't go back there. That would be my next guess. They're 'usually' easy enough to test and you can likely replace it yourself. But does the CEL/MIL light ever come on while she's driving?

cwerst Posted November 11, 2016 Author Share Posted November 11, 2016 The alternator was my first thought when she was having starting issues, so I had it tested before and after I replaced the battery and it was good. But as far as the CEL/MIL light, I haven't noticed it when driving and she hasn't mentioned any lights on before either. I've also checked fuses but that is the limit of my knowledge of electrical issues. I know to check the battery and it's terminals, alternator, and fuses. It seems that everything in the cab and on the exterior work fine from an electrical standpoint but the engine is different and I am lost. Link to comment Share on other sites More sharing options...
wtdash Posted November 11, 2016 Share Posted November 11, 2016 (edited) Well....I'm not the 'diagnostic expert' on here, so others will likely have other ideas. Miles? Might want to get a Code scanner (CANBUS compatible) to see if there are any stored codes? "not wanting to start" = Turns over/cranks? Or just 'makes some noise'? Next: - MAF sensor - based on what I see online, yours has one- it's next to the air filter on top of the intake tube. On older Subies it was a somewhat common failure point...but yours should have a code. - Fuel pump - not sure about this on newer - 2005+ - models. And Fuel filter, but that may be in the tank too... - cam and crank sensors? - ?? Edited November 11, 2016 by wtdash Link to comment Share on other sites More sharing options...
cwerst Posted November 28, 2016 Author Share Posted November 28, 2016 Thank you all for your help after driving it a few weeks myself with no issues, my fiancee started driving it again and on saturday it threw a check engine light. I was able to get it read this morning and it has a crankshaft position sensor throwing code. I bought the replacement part but could use some advice as to how to replace it. Any info you guys could provide would be very helpful. Thanks cwerst Link to comment Share on other sites More sharing options...
