I own a 01 Lincoln ls 3.9. It started with dead fuel pump, and progressed to losing my tail lights and dash cluster. And now I have to power to my head lights. I checked all my fuses and found 8-12 have no power.I checked under the hood and also no power to my pcm. I had a blown fuel pump fuse replaced already. And I also had a blown heated mirror fuse replaced. When I replaced those fuses when I lost all power to my Lincoln. Iv been worken on cars for years and im stumped.

Check all the fusible links and test the headlight switch

Test for voltage at head light bulb as well as the fuseable links by the starter. If the links are good. Check the voltage at the dimmer switch harness and it transfers voltage properly. If not you going to have to replace the turn signal switch.

I did this also. I could not get a reading at all. I forgot to mention that while I was testing the pump the horn went nuts and when u turn the key It was acting like the battery wwas going dead. On currently holding 8.7 volts in the battery from my wife cranking trying to start it while it broke down. I can't get any power at all in the car.

You need to check the voltage at the headlight switch. Start there.
