i have a2003 alero that would crank but not start . plenty of spark would only start if i used starting fluid or gas into the spark plug hole. but once it was started it would restart as long as there was still gas or fumes in the cylinders I spent hours and hours researching different web sites. spent hours running different tests and tempted my self to start changing out parts. One website said check ALL your fuses under the hood and at each end of the dash even if you don't think they're related to the problem. thats what i did. I found a blown fuse that was marked A/C BFC. I changed it and the car started right up. apparently it controls the flow of fuel somehow . the fuse may have gotten blown by snow ,slush or ice from our northeast roads getting packed into the area around the A/C compressor. changing that fuse saved me hundreds of dollars in parts alone.
