Before starting the engine drain the condensation from the fuel tank, there should be a drain on the bottom.Then I would replace the fuel filters and prime. Next would be replacing the oil and filters (pre-fill the filter), and then check the air intake for nests or holes, and replace the air filter if necessary.

After that I would try starting. Let it crank for a little while before trying anything drastic so that oil can begin to circulate. Good batteries are necessary as a diesel will not start well at low RPMs cranking, and be sure you don't crank too long as you will overheat your starter.

If it doesn't hit after a little cranking, you can try a little WD-40 as a starting fluid. You might or might not have an ether starting aid, but I recommend against using ether as it can stretch head bolts and also it washes the lubrication off of cylinder walls which can cause scoring.

Once you get it to run, keep an eye on your oil pressure, and on your fuel filters. You might have to dispose of the fuel if you have a severe algae problem, algae grows in diesel fuel tanks in the condesation on the walls above the fuel, and you will probably see it in the filler neck if it has a severe case. The fuel itself should be good.

Before running it on the road, it is a good idea to replace all of the engine coolant, bad coolant can kill a wet-sleeve diesel. You will want to run a good coolant, with distilled water, and NO MORE THAN 60% Coolant in your water.

Good luck.

For information on any of the systems in the coach, there are plenty of us out here with manuals and knowledge. If you don't have any luck at this site, hop over to www.wanderlodge.org and we can help you there.

I think if it were me, I would pull both head pan covers and six injectors. Then I would carefully spray a light oil
into each cylinder and let them set a day or so. DO NOT EVEN TRY TO ROLL THE ENGINE OVER UNTIL THIS OIL SOAKS IN WELL. The reason being that your engine has set so long that it may have rusted the pistons & sleeves and if you move the pistons without lubrication you could score piston sleeves. In a day or so, bump the starter so the pistons move to new locations but not far, and then oil again. Replace and reset injectors and pans an try cranking it. Of course you will need new batteries as well. Then I would try to get it to a detroit dealer or truck dealer who HAS SOME ONE WHO KNOWS HOW TO WORK ON THE 6V92. Believe me when I say not all Detroit dealers do!! From there it is a matter of checking systems to see what works. Do not try to jump start the thing and remember that when you pull the injectors you will remove the control rack. This must be reconnected before trying to start the engine, otherwise the engine will run away and destroy itself. I would also drain any fuel in the tank and use it to kill unwanted grass, and replace it with fresh fuel. If you do not feel confident in doing these things then find a good 6V92 man.
Of course follow the advice about changing oils and the filters and change the one on the transmission too.
