mikaleda Posted January 10, 2015 Share Posted January 10, 2015 Is the check engine light on? If so I would try and pull the codes and see what is coming up. Also is this a multi port fuel injection? I'm not familiar with this model of Subaru so I can't be sure what kind of fuel system it has. Link to comment Share on other sites More sharing options...
Fairtax4me Posted January 10, 2015 Share Posted January 10, 2015 When its warm the engine turns over but it just won't start? That's usually due to a bad Engine coolant temperature sensor. The sensor fails and is telling the computer the engine is cold all the time so it gets too much fuel and floods the engine. 1 Link to comment Share on other sites More sharing options...

Check engine light is not on, this model doesn't have computer to read the codes. Link to comment Share on other sites More sharing options...

I know that some non usdm models of subaru still used a carb and disty in the 90's and would have a different setup for the fuel system monitor than multi port Link to comment Share on other sites More sharing options...

I left my car in my official service, now i can't start up even it is cold or warm(I couldn't start it at all) Link to comment Share on other sites More sharing options...

mikaleda Posted January 10, 2015 Share Posted January 10, 2015 I think it is mono injection system Okay that sounds like throttle body injection. I'm assuming you have the 1.2l 3 cylinder? Link to comment Share on other sites More sharing options...

mikaleda Posted January 10, 2015 Share Posted January 10, 2015 Okay, I'm trying to find info on this particular engine. Very cool subaru I wish we could get these in the states. Link to comment Share on other sites More sharing options...
mikaleda Posted January 10, 2015 Share Posted January 10, 2015 Okay from the info I found the EF12 is the engine you should have in this car. The two fuel system options it came with is a 2 barrel Hitachi carb or a multipoint fuel injection system I found some pictures please tell me which one your engine looks like This one http://upload.wikimedia.org/wikipedia/commons/thumb/3/36/Subaru_ef12_justy_engine.JPG/440px-Subaru_ef12_justy_engine.JPG Or this one http://upload.wikimedia.org/wikipedia/commons/8/87/EF12engine.JPG Link to comment Share on other sites More sharing options...

mikaleda Posted January 10, 2015 Share Posted January 10, 2015 Crazy, this Subaru is hard to find info on. Well I would start with the basics. First do you have spark? Link to comment Share on other sites More sharing options...

libero1 Posted January 10, 2015 Author Share Posted January 10, 2015 Crazy, this Subaru is hard to find info on. Well I would start with the basics. First do you have spark? In service they suspected on the induction coil, they replace it with their induction coil and it give the same parameters. There is no power or spark.

mikaleda Posted January 10, 2015 Share Posted January 10, 2015 Okay now were getting somewhere. A little more searching shows that both models have a cap and rotor, i would try changing those out and seeing what happens. Sometimes the cap or rotor can get a hairline crack causing loss of spark Link to comment Share on other sites More sharing options...
mikaleda Posted January 10, 2015 Share Posted January 10, 2015 Also could be an ignition control moduel if this model has one Link to comment Share on other sites More sharing options...
libero1 Posted January 10, 2015 Author Share Posted January 10, 2015 I will change those parts and see what will happen. Thank you for your time Link to comment Share on other sites More sharing options...
