    Guys,

    I have tried to a search for a similar problem, however I haven't come across anything and am hoping you can help.

    Earlier today, I changed the plugs on my 86 328. I started her and she ran well after the plug change. Then I opened the air filter to see what shape it was in, at this point, I decided to start the car to see how she would run with the filter out. I did not put the air filter compartment back together and just started the car. It started fine and ran well for a few minutes while I was revving her, and then she died. When I turned the key in order to try restart her, I noticed the fuel pump was not coming on, and also the 'Fasten Seat Belts' light was not on. Obviously she cranked but did not start up. I then dug further into the fusepanel, and turns out I now do not have power to a number of my fuses. From what I can tell, I dont have 12v to a number of the fuses on the left side of the panel.

    Any thoughts or guidance would be greatly appreciated.

    There's a general relay for ignition switch items. Check it out.

    Where would this relay be located, and would it also control the power for the window motors, as I also do not have any power to them as well.

    Relay u in the figure Paul posted.

    Yes. Not having the windows work when the key is "on" is another sign that relay u might be the trouble. You can remove relay u and install a jumper wire as shown in this jpeg between the terminal 30 contact and terminal 87 contact to simulate a "closed" relay u. If the windows work with the jumper in place, try a new relay u. If the windows still don't work, the trouble is futher upstream most likely:

    Guys,

    Replaced the relay, and I am back up and running! Thanks again to all of you for your help.
