I'm a Toyota disciple up in Alaska. I love my truck! It's a 91 SR5 with 147700 miles. I am hoping to find among you some Toyota gurus who can tell me why my truck has an intermittent starting problem. I seem to have plenty of juice available to lights/ gauges, etc. It doesn't do anything when I turn the key - not even a click. Have cleaned battery terminals and connections. Jumpstarting doesn't work. And if I let it sit it will eventually (overnight, a couple hours, whatever it wants) start. Have tried different keys. Normally I don't have any trouble with it, only a couple times a year for about three years. But the not knowing when I'll be left sitting is very frustrating. Any ideas?
Thanks!

I am guessing it's the starter wire at the starter. You have the big wire from the battery, and the smaller wire. I bet the smaller wire is corroded at the connection.
