Maybe a Starter Solenoid Problem??
 

Well, I went to start my truck the other day and all the Acc. came on but it wouldn't crank. It sounded like the solenoid on the starter was engaging but not all the way so the starter wouldn't crank. I tried it a couple more times and then I couldn't get the solenoid to work at all.

All the Acc. come on when I turn the key and I tried jumping it so I know its not the battery. The starter just won't crank.

So what I'm asking is do you think my diagnosis of the Solenoid being bad is correct or do you think its the starter all together? Or maybe something totaly different?

Thanks
