ok, so i got a 86 runner it is automatic.When the guy 1st started it up had a little trouble he said it had been sitting seemed like it made sense battery was from '06 and it was a little corroded. I cleaned them up it would still just click replace the connectors, no solution. I went to interstate had battery tested they said charge was pretty low so I got another installed it and it worked after a few tries from there after no luck, no start no click like it would before ,so we got a tester and tested the starter that cranks really easy. so we continue to check wire connecting the ing. to the starter with a multimeter no signal. The guy had a alarm installed so it really doesn't look factory behind the dash at all. I was wondering what relays could i check or something that is very common I know there are other threads about similar problems but i really think that this is a special case.
Thanks
(my dad thinks it has something to do with the alarm anything could help thanks so much)

 

First off, Try to use periods and revise your posts before posting. The entire post is completely confusing and hard to follow due to the run on sentences and information that is not needed.

Secondly, Do you have power to the ignition? Do the lights come on when you turn the key or is it completely dead? If it is dead try to re-wire the wire that comes from the fuse box underneath the hood.

It could be related to the alarm. If that is the case all you have to do is pull off the panel near the ignition and un-hook it.

 

revised and when you turn the key the clock and every thing dimms like its the battery but it did that when it would start and yes there is power to the ignition.

 

Have you tried a different battery?
I had a bronco do this, turned out the battery just completely was dead. Showed 12v from the posts, but wouldn't hold a charge and DEFINITELY couldn't start that 302.

 

yeah i replaced the battery yesterday started one time then after that nothing im sure its something to do with the ignition im tearing the dash off now any tips haha

 

Check to make sure the battery has charge..
Like i said, i had a battery that was pretty new show 12v at the post, but still not start the truck.

 

well unless interstate battery's are going to fail 2 times 1 of them is fresh from there warehouse brand new both showed 12v at the post, will light up everything in my truck I'm sure its not the battery (don't mean to sound douche-y if i do)
