pa9213 Posted September 4, 2021 Share Posted September 4, 2021 I have a 1981 Subaru DL 1.6 engine. I cannot get fuel to the carburetor. I have not started the car in about 2 years. I have a new fuel filter located under the car at the back and no fuel gets to their. My fuel pump in located under the hood. I have started the car with starting fluid and it runs fine for about 3 seconds. Could someone suggest what I can check to locate what is wrong? Thanks Paul Quote Link to comment Share on other sites More sharing options...
pa9213 Posted December 1, 2021 Author Share Posted December 1, 2021 Can you tell me where on the 1981 Subaru DL 1.6 engine the Fuse is for the Fuel pump? The Wiring Diagram the Wires are colored different on mine. I have checked the fuel pump and it runs. Any help would be appreciated. Quote Link to comment Share on other sites More sharing options...
moosens Posted December 1, 2021 Share Posted December 1, 2021 I’m thinking a DL 1600 of that era is a leftover from the previous 1600’s of the late 70’s. So you want to verify that your alternator and voltage regulator are working well. Did you jumped wire the pump to verify it’s working or just turn the key and see that it pumps ? And does it pump more than 3 seconds ? Quote Link to comment Share on other sites More sharing options...
moosens Posted December 1, 2021 Share Posted December 1, 2021 Fuse box under the dash on the left side ? I don’t have a good recollection at this time since I ditched the 80’s cars two decades ago or more. Fusible links up front in the engine bay for sure. When I get home I’ll check a factory manual from 1982 , also has 1600’s with the 1800’s Quote Link to comment Share on other sites More sharing options...
pa9213 Posted December 1, 2021 Author Share Posted December 1, 2021 Thanks for asking. I have replaced the Voltage Regulator and I have tested the Fuel Pump and it runs well being jumped from the car battery. The fuse box is located under the dash and I have checked all of the fuses and they are good. I will be rechecking them because my son say that the engine fuse may have something to do with the fuel pump. I have also found that the fuel pump wiring goes to the EMC box. I have not had time to check the wiring to see if it could lead me to what is keeping the fuel pump from running when starting the car. I have started the engine by putting gas in the carburetor. The engine runs well accept the fuel pump. Paul Quote Link to comment Share on other sites More sharing options...
moosens Posted December 2, 2021 Share Posted December 2, 2021 Those glass fuses can be bad and easily overlooked when the glass has separated from the metal end cap and it LOOKS like it’s ok until you tug on the end cap and it reveals itself. That is assuming yours is like the previous 1600’s and I’m pretty sure yours is mostly carryover of that era for engine electrical. The factory service manual suggests to exchange both the alternator and VR at the same time on the previous 1600’s 1976-79 But now that you mention the EMC box I think that begins in 1980/81 so that could be something I’m far from familiarity with.

OldieSubie Posted January 11, 2022 Share Posted January 11, 2022 Can someone post a picture of the voltage regulator? I have an 81 DL 1800 and I think someone jerry-rigged a relay as a VR. And it's been the bane of this cars existence since I've become an owner. I have been searching everywhere for what the grey harness connects to, and I think it is the Voltage Regulator.

moosens Posted January 11, 2022 Share Posted January 11, 2022 As best as I can recall a car from 1981 being a DL 1800 would be internally regulated (alternator). Quote Link to comment Share on other sites More sharing options...

My wiring diagram shows that the alternator goes to a voltage regulator....and that just happens to be where a previous owner installed a relay and crammed 6 out of the seven wires into three wires to fit the relay. I've been trying to figure out where the grey connector goes to, and this post gave me the much needed breakthrough! Quote Link to comment Share on other sites More sharing options...
