I have a 2008 Job1 F-350 SRW, Spartan 275 tuned. I tried to start the truck yesterday twice and I couldn't get it to turn over. I got new batteries and tried to turn it over. The first time, after holding the key for about 4 seconds it stopped turning over and I just heard a grinding noise and free spinning underneath the truck. I'm assuming the starter? Since that happened, I've hit the starter and tried to restart twice and I get the same noise. I'm in northern NY so it's pretty cold, not sure if that's a factor. I appreciate any thoughts or help.
