HELP!!!!!
i have a 97 6.5, replaced the starter with a used one, was cranking over but no start, now will not crank over now. I have 2 1000cca batteries in it. turn key wait for glow plugs then it just clicks. connections are good as i am a heavy duty mechanic but i still have not got my head around these 6.5L.

any help will be awsome. would love to have this truck on the road again
