Had a battery go bad so replaced both. Truck still hesitated to turn over and I thought that I had burned the starter contacts. I pulled the starter and contacts were showing wear, but not bad. Finally the old lightbulb went on in my head and I remembered the underhood relays. Sure enough, close inspection showed slight corrosion on the contact pins. Cleaned and reinstalled. Problem gone. Hope this may help someone else.

Good deal on the fixer,I mightadd that I bought the truck I have now used a few months ago,and am preparing it to go on a 10k trip thru Canada and Alaska next summer,I have been going thru it with as some say a fine tooth comb,The guy I bought it from had just installed a new starter,as part of what I am doing,when changing the fuel lines above starter I orderd fuel lines,and a starter repair kit from www.fostertruck.com I bought the starter kit to carry with me, when I got it I was amazed at the size of the starter contacts,so I went in to the starter as I already had it out,and the starter was I guess to be around 5 months old and the starter contacts was not bad but they were burnt so as a precaution I changed them, the starter contacts he sells is well worth the money.Goodluck and hope this helps some one too!
