Default 85 pickup starting issue

The truck sat for about a month and now it will not start. First thought the battery was dead but it isn't. When I turn the key over the relay on the passenger side by the glove box clicks once. I have power going to the relay but nothing going to the starter solenoid. I have power from the battery to the starter. If I cross the terminals it will turn over. Does this sound like a bad relay? Not much to the system but I can not figure it out. If its not the relay I am going to do push button start and get rid of all of the crap. Any help would be great.

If you have power going into the relay, and power coming from the key to the relay, but no power out, you have a bad relay.

If you cobble it with a push button you still need a relay, the switch won't handle the load for long, that's what relays are for. Just replace the relay with a new quality one and make sure the connections are good.

That's what my plan was is to replace the relay. If it is more then just a relay I will make my own relay setup and clean up some of the factory mumbo jumbo. I will double check to make sure I have power from the key to the relay but I am certain I checked and did. Just nothing after the relay. Turn the key and "Click"

So I finally had a chance to look at the truck. I decided to jumper the relay and try starting it and bingo she turns over. Jumpered the big black wire that has 12v when the key is turned to the blue wire with brown stripe. I'm guessing all I need is a new relay. $73 at my local auto value. Sound right to everyone else?

The only 2 parts I have seen fail are the contacts in the starter (which is not your problem) and the ignition switch in the column. The bad ignition switch leads to a single click noise and no crank. The ignition switch is about 35 dollars.

If the ignition switch was bad why would it turn over with the key when I jumper the relay?

Right. The research I have done pointed out the same things you mentioned. Thanks.
