Hi, I have a 1986 f-150 with an efi 302. It was working great but one day it wouldn't start. We finaly got it started by pushing the gas all the way to the floor. It still won't start sometimes. We've ran a fuel pressure test and It's within specs. We've also tested the spark and fuel pumps. It's getting fuel and spark, but it still won't start unless we hold it on the floor. Does anyone have any ideas?
