car hasn't been driven & sitting up for about 1 1/2yrs, and i can't get it to start. The engine is cranking up but it just won't turn over & start. I'm pretty sure that it's getting spark. And when i took off gas cap from fuel tank, it still had pressure. Which leads me to believe that it's not the fuel pump. And i'm sure that it's not getting gas to the carb because when i put a little gas in the carb it starts up but soon die's out. The only thing i can think of is the fuel line is clogged seeing as how it was sitting for so long without being driven. Suggestions please.
