start up procedure
When I parked the truck I filled both tanks full w/ diesel and disconnected both batteries.
Should I do anything to the engine before I crank it, as far priming the fuel system or anything?
Thanks for the help.
1, Probably a good idea to put in new batteries to start. Given the age if the old batteries still hold a charge they probably won't be putting out enough amps and you risk damaging the starter during prolonged cranking.
2, Diesel Fuel does deteriorate over time and eight years is a long time. If you are in an area that gets pretty warm then the diesel fuel can go bad even faster. An algea bloom in the tanks is a distinct possibility in that amount of time. Although the algea may have long died off it leaves solid residue in the tank which can quickly plug up your fuel filter.
3, For Diesel engines that have sat for long it is aways a good idea to pump up the oil galleries first to avoid risk spinning a bearing during the initial start-up. Remove the oil pressure sending unit and pressure some 10W40 oil into the oil galleries. If the above seems like to much work turn the engine over by hand a few times using a socket on the front damper. In eight years most of the oil would have drained from all the bearings and oil galleries into the oil pan.
4, Install a new fuel filter and fill it with a good additive such as Diesel Keen before re-installing the filter. This will help lubricate the injection pump and injectors during initial start-up.
5, Make sure your Wait To Start Light stays on for about 10 to 15 seconds prior to cranking the engine, this is a good indicator that the glow plug system is working properly.
6, Pull your front break pads off and put some neverseize on the caliper sliders, they would have rusted up pretty good in eight years of sitting.
Milage is also fantastic at 18-19 mpg city; especially if you compare that to a 2005 Duramax automatic at 15 mpg city. The newer trucks may have more power, but sure disappoint on milage.
