I'd first suspect a bad connection at the battery, or a bad ground connection. I'd remove battery cables, clean the connections and reinstall. I'd also remove ground nut above battery, clean and reinstall all wires.

done all that.. cleaned every connection at the battery and above the ground..could just a weak battery cause this?

That's to warn you that you have a disfunctional glow plug, they're supposed to do that when there is a glow plug issue.
