SAR JK r2.8 Cummins conversion

Does it have glow plugs?
Have you confirmed they're wired up and working?
All the diesels I've driven with glow plugs have had no trouble well into the negative F temperatures.

Heat grid on the intake. It should have glow plugs, but Cummins decided not to for reasons (I hope).
