Uh...I dunno if my battery is even strong enough to crank my bitch for 1 minute. r u getting fuel to it right away? When I let the tank get
really low (like the needle on or below "E", it takes about 10 seconds for the fuel pump to suck fuel up from the tank, as opposed to about 3 cranks when I have fuel. I don't know any real good way to test this, other than to spray fuel all over yourself while someone cranks it for you.
