DaveT Posted June 18, 2015 Share Posted June 18, 2015 Dashboard lights are not controlled by the ECU, except for the check engine light Quote Link to comment Share on other sites More sharing options...
SoobDood05 Posted June 18, 2015 Share Posted June 18, 2015 (edited) Since its fuel injected check your fuel pressure. Or use a noid light to make sure the injectors are being pulsed. Isnt there I fusible link to the injectors you can check? Someone else may be able to clarify See if theres anything electrical these components share. Always start with spark, then fuel, then compression. If you confirm all three then the problem is elsewhere.

Loyale 2.7 Turbo Posted June 18, 2015 Share Posted June 18, 2015 ... Isnt there I fusible link ... Yes, check the Fusible Links on the black box, on the Radiator overflow tank. Kind Regards. Quote Link to comment Share on other sites More sharing options...
wagonist Posted June 18, 2015 Share Posted June 18, 2015 Also, is this the earlier EFI with flapper style MAF sensor on the airbox, or hot wire? 87 is when Subaru changed, so it makes a difference. The earlier ones have a problem with the fuel pump electrical circuit through the ECU., so the fuel pump stops working. Just need to connect the earth wire from the pump to the body instead of letting it go through the ECU. Quote Link to comment Share on other sites More sharing options...
