My 72' roadrunner and 71' charger R/T both sick right now?

My 72' RR is a 340 auto, and my 71 R/T 440 auto both are not starting but do run for a second with a blast of starting fluid both have less than a 1/4 tank of fuel any thoughts thanks.

How long they been sitting? getting fuel in the carb?

Did you put them up with ethanol????

they have been sitting about a year and a half

i havent checked to see if fuel is reading carb yet
