Reza Posted May 27, 2012 Share Posted May 27, 2012 I am new to this forum and have already posted on intro page. I have been pulling my hair out on a 1980 subaru gl wagon to no avail, I need some help trying to diagnose two electrical problems. I am getting no power to the fuel pump after it starts running. It gets power while cranking but that's it. and after it is running on the limited fuel it does not turn off with the key i can turn it to the off position and it keeps running till it dies from lack of fuel. Iv tried 3 different regulators, I can turn the fuel pump on manually while running by connecting the circuit in the regulator. Iv tried another ignition switch no change Iv swapped in 2 different alternators since i know these run off the charging system. Iv tried another fuel pump any ideas?

Reza Posted May 27, 2012 Author Share Posted May 27, 2012 ok, duh. I was using an internally regulated alternator. thats done, as for the turning off issue could that also be attribute to the wrong alt. as far as internal systems and external.
