Question
Do I need to drop the fuel tank and start fresh? My Sunbird has been sitting outside for 7 years uncovered. Engine is like new with only 10,000 miles. Started it 6 months ago and ran rough...you could smell the old fuel (1/4 tank). Today,changed plugs added 2 gal fuel, but won't start. Fires with starting fluid or when primed with gas.
Is there an easy way to get rid of the old gas, short of dropping the tank? There seems to be an anti-siphon screen in the filling hose. If I need to drop the tank...how do I accomplish this? Will I need to change the fuel pump and fuel filter too? I really appreciate any help you can give.
Your fuel pump may be frozen. Are you getting any fuel in the carbs?
If not, change the fuel pump. Also, change the fuel filter and yes, dump and clean the fuel tank. You should have a drain plug somewhere on the tank. If not, you will have to drop it. I'm betting you also need new plugs, wires and points after sitting for 7 years.
