Solved - No power to fuel pump, radio, windshield wipers, etc

85 Ford T-bird - 5.0 HO swap - 5 speed

Tryn to get the tbird going after sitting about a year.  Got plates and a battery for it.  Problem though.  Hooked up the battery but the fuel pump don't run, power windows don't work, no windshield wipers, no radio.  Car has been sittn a while so I'm sure its something with a ground or wire somewhere.  I relocated the battery to the trunk years ago when I did the 5.0 HO swap and everything had been working for years.  I checked the ground at the battery. Sanded it all up etc and it sparked when I hooked it back up so it's got good connection there..  It cranks fine, dash lights all work, interior lights work, cluster lights work, but fuel gauge doesn't show fuel level upon putting the ignition in run position.  All the head/tail lights and signals work.    I checked a few of the fuses and they were good. Not sure what's going on exactly. I was wanting to drive this thing this weekend to knock some of the rust off and get her purring nice again.  Darn it!!  Any help would be greatly appreciated.  Thanks.  Jason.

Leave that positive battery cable undone until you get the ign switch replaced. You probably know this, but just in case.

not sure about te radio and all, but there's a connection by the battery that i've had come apart and the fuel pump wouldn't work. i was all like "wtf?!!?" until i found out that i had disconnected it when i had replaced the battery. check it.

Yes, I'd check the fusible links on the starter relay first (check their condition AND make sure they're bolted to the proper side of the relay, IE the side closest to the battery), then the ignition switch. As V8Demon said, if you find it to be the ignition switch, disconnect the battery and leave it disconnected until you replace it.

Usually when an ignition switch goes you lose the turn signals, gauges and blower motor functions but the car will still run. Usually.

Ok, and the winner is ignition switch.  Thanks for the tip.  When I pulled the column shroud off the ignition switch fell apart.  Hopefully the borg werner inition switch from Oreily's will last longer.  These dang things are rediculously troublesome.  Thanks guys!!!
