Just wondering if anyone has had this problem. No voltage at the little wire when you turn the key so solenoid doesn't pull in. I am hoping someone says it is just a fuse somewhere! The truck is seldom used these days, I am using an aftermarket key if that matters. I can and do start the truck by jumping the solenoid. About 120K miles. Anyone know where the wiring diagram is for this truck? I realize this isn't a Chevy truck, but I figure there are a lot more Chevys out there!

Thanks for any help you may be able to provide.
