Dodge started using the 5.9L Cummins engine in the 1989 model year.
Remove the fuel filter, fill it with fuel... IIRC, the Duramax has an electric fuel pump... cycle the key in the "on" position a couple times to let it prime.This is, of course, assuming that, when you say "gas", you actually mean #2 Ultra Low Sulphur Diesel, which is the only fuel you should be using for that engine, especially if it's 2007 or newer.If you ran that diesel engine on gas you probably destroyed the engine. That's why it won't start.
To start the engine
Ford did not start using the 5.4 in the F-150 until the 1997 model year
Smoke is just unburned fuel, too much smoke is not good for the engine. Anything that causes the engine to run rich, or have more fuel in the fuel to air ratio will make it smoke. You can either put in more fuel by using a better lift pump, or using better injectors, or you can starve the engine of air (not recommended) by unhooking the turbo or putting a paper bag over the air filter. Smoke is just wasted power, a truck that burns all this extra fuel runs much faster. Note that the fastest duramax in the world blows little to no smoke.

1975 model year.
You need to find out if the fire or fuel quits and go from there If your Subie is a newer model (mine is 2015) you have to unlock it with the remote-equipped key, and start it with the same key. Otherwise you can run into the "engine immobilizer" that kicks in if you are not using the correct key with the proximity sensor built in.
Made first one in 1967 295hp
Push the starter. Crank the engine. Turn the key.
Using the wrong weight engine oil for that climate, The battery/electrical system is not in good condition,
You wouldn't happen to be using too heavy of an engine oil ? What grade of engine oil are you using ?
