Make sure you have a good battery; charge it, load test it, warm it up indoors before your start attempts if you can. A spare battery is a good idea as well.

Obviously, if it has a block heater and you can get power to that, use it to warm the engine before trying to start it.

You might as well take the opportunity to test the glow plugs. Not sure what spec is on the 190s, but they should all read very low resistance on a volt/ohm meter.

You've probably lost prime on the fuel pump unless the system is exceptionally well sealed. If you don't have a primer pump or it doesn't seem to be working, one trick is to disconnect the supply and return lines, then use an air compressor to put a few psi of air into the tank through the return line, which should move fuel down the supply line. You have to do this very gradually, not more than a couple seconds of air flow at a time. You can also use a MightyVac or similar to pull fuel down the supply line with the return line disconnected or the fuel fill cap off. If you do that, make sure you have a collection jar hooked up (used for bleeding brakes) or length of clear tubing so you don't suck fuel into the vac.

Once you have fuel at the IP, you can open up the lines at the injectors and crank until you see fuel there, then re-tighten. This will also move some oil around the engine. Don't crank more than 20 seconds at a time, with at least a minute in between tries.

I'm not sure if the 190 requires manual valve adjustments, but if it does, having that set correct will be critical to getting enough compression to start the engine.

DO NOT under any circumstances use ether or any other 'starting aid' with the glow plug system energized.
