Exhaust temp (max im guessing)is stated in the specs as just over 1200 deg. Interesting.

You should start a new thread about your rig where everyone will see and respond. But start with new oil and ALL NEW fuel and filters. Replace 1/4" fuel return line out front of Ip with clear tubing to watch for bubbles indicating air intrusion into fuel lines. Remove all glowplugs add a few drops of oil into each cylinder. Turn engine over by hand, then with starter while all the plugs are out. After cranking for 30 seconds you should be getting a mist of fuel out the glowplug holes. Install new ACDelco 60G plugs and try starting.

Start the new thread for any questions and/or to let us know how it goes.

EGT is nothing more than heartburn. If you have a turbo it tells you where the turbine melts, maybe. I have run a 1985 6.2 with a DS4 and ATT turbo to 1550 degrees steady pulling a grade. As long as the ECT is under control and timing isn't advanced EGT can be ignored. On this engine anyway. NA engines run higher that that 1200 EGT anyway : stock.
