Novel approach, a red hot piece of steel, crank the engine for ten seconds then blast the air intake with pure O2 from a torch (high altitude). Never failed. Did not imply to mean Cummins had glow plugs. But I sure stripped out a lot of series parallel switches, and changed 4 wimpy group 4 batteries for the heaviest 31's I could find, along with a 50MT starter motor for the 400+ horsepower tractors.
Just the tiniest slowdown can making starting difficult. For jump starting I series a 7-D with a 150 lb 8 volt battery, and a massive solenoid. Have the driver crank the starter and then hit the system with 12+ under full load volts.
Got many a bus started at Mammoth Mountain Ski area, that way. 28 volt battery jumper system that was recharged at 32 volts. No one else would go up there when it was -20 with a 40mph wind. Magic was a 200,000 BTU LPG space heater aimed right at me. The momentary solenoid control was the key, let the engine crank then zap it with higher voltage.
