Many thanks to all! @paraclete: a plentiful supply of liquid bread is always on hand
So trying to get the 09 running after xmas... changed the oil (nice black color, no signs of water or debris); drained 15 gals of old diesel out of the tank (no signs of water or debris), added 5 gals of fresh with some fuel additive; new fuel filter; 2 group 31 Napa commercial batts (ouch!)... any tips on priming the injector lines?
And a couple of underhood pics:
The resistor bypass was already done, though I've now disconnected the 24v supply and may remove the resistor bank entirely. The truck was converted to a manual glow plug switch and they used what looks like a C-code civvy relay for it. Idiot lights all work though the volt meter isn't functioning.
Once the motor is firing I'll be doing a coolant change...
Future projects:
1. Doghead mod (if not already done)
2. Fix the voltmeter
3. Restore the glow plug system to stock (keeping it 12v and piggybacking the manual switch for backup)
4. Fixing the window regulators (drivers and back windows both don't crank properly)
5. Adding a USB power supply in the ashtray tray for phone charging and such
