Ooooorrrrrrrr "smelling salts" comes in a can
non petroeum product. As a "last" resort I'll let the glow plugs go out, let 'em cool for a minute in sub freezing (10+) and hit the air cleaner intake with 2 seconds of ether. use only in an emergency. Not reccomended for faint of heart. Usually used on closed course with a professional driver.

Hate to hear that 'death rattle' when it takes off, but like I said, use in extreme emergencies.

Many remote diesels have direct injection starting fluid into the intake mainifold as the only starting aid. But that is without plugs.

I think the military has direct start and you have to hit the deuce and halfs and 5 tons with ether. Never blew one with ether. They were Cummins straight 6's NTC's. used the same thing on 2 cycle Gimmies. Scary times.
