2002 E.450 c.class starting issues

I have a 2002 e450 v.10 c.class with 26,000mi sat for 3 mo. Went to start it it back fired a couple of times then tried again it started ran kinda rough. Went out a month later it was supper hard to start would barely hold a low idle. Went out a month later even harder to start and if it did it was for a second or two. If I keep cycling the key 5 to 10 times eventually it might start for just a second and have a very low idle but if I touch the gas pedal in the slightest it dies. I changed the fuel filter,air filter. checked the fuel pump and its pumping out fuel at every key cycle. Checked the inertia switch its ok.not sure what else to try? Won't run
so can't take it to a repair shop.
Class C

    Tried to drain the tank but the hose I was using would only go in about 2 ft then stop.

    Stabil won't do anything for old gas. You need to drop the tank and flush it. Then you'll need the entire fuel system flushed ($$$$). If you add more good gas, you'll still have bad gas, just more of it. Spme one will mention "Seafoam", but that won't get rid of the bad gas either.

    I,d rather think moisture is forming in your low fuel tank. don,t cost to much but add couple cans sea foam and fix it with three gal good gas. never ever let sit with a almost empty tank.be patient let sit for a half a day.

    Pulled out a gallon of gasoline through the fuel pump and it looks clean no water.

    Having a rig sit for 3 months is no big deal ... most of us let our rigs sit that long during the winter months w/o experiencing a problem. And gas sitting that long should not present a problem for an E450 - I doubt seafoam is going to solve your issue.

    Agree with Wizard ... having a stuck IAC would be something to rule out.
