Late 99 F250 7.3 won't start unless plugged in when temps drop below 40f. Checked the GPR and it seems to be operating fine. Is it possible that all my glow plugs are bad? I've heard of 1 or 2 going bad but never all 8 at once. I need the truck for work and I can't use it if it won't start at the end of the work day. Any suggestions?
