ivantruckman Posted January 5, 2010 Share Posted January 5, 2010 will it run if you put a small amount of gas down the carb ? Link to comment Share on other sites More sharing options...
notsosubaru Posted January 5, 2010 Author Share Posted January 5, 2010 its fuel injected. Link to comment Share on other sites More sharing options...
rpholz Posted January 5, 2010 Share Posted January 5, 2010 its fuel injected. so spray some carb cleaner down the throttle body and see if it turns over. are you positive its fuel and not spark related? Link to comment Share on other sites More sharing options...
notsosubaru Posted January 5, 2010 Author Share Posted January 5, 2010 it starts up so not spark related Im thinkin. The car also sat for for 3 weeks with a pretty empty tank so possibly condensation got into the tank?? Tried HEET to remove water vapor but will only start and drive a little ways after sitting for more than about 12 hrs...Frusturating!!! Link to comment Share on other sites More sharing options...
MilesFox Posted January 6, 2010 Share Posted January 6, 2010 you have a big canister filter under the hood behind the driver strut. the fuel pump is located on a mounting plate just ahead of the passenger rear tire, there are 3 bolts, the pump sits on top. you will more than likely break the bolts taking it apart, but that is to be expected. first check for voltage to the pump. if you have volts, check for ground. the fuel pump grounds to the ECU, but you can bypass ground straight to the body. you can use any spfi or turbo fuel pump frpm parts cars. otherwise you can buy a generic universal in-line fuel pump for about 60-100 bucks, depending on store/online, etc. if the parts counter has a hard time finding one under a subaru listing, try a ford f250 with secondary tank, main thing is in-line unit and fuel pressure rating of at least 40 or so lb.

ragzuk Posted January 16, 2010 Share Posted January 16, 2010 if this is still an issue i just had this prob with my gl10 at my friends house same story really got there and wouldn't start..after hours of checking wires it was the ground wire to the fuel pump just pop the back seat up (on the gl10) and try running a diff ground to your pump see if that helps Link to comment Share on other sites More sharing options...
