The usually very reliable 351W in our eight truck is on a temporary hiatis meaning it doesn't want to run. It's getting gas (I can see it going into the carb when I turn the fuel pump on) and it's getting spark (although maybe not enough to ignite) but she wont run. When we try to start it it just turns over and over sometimes it sputters for a minute but doesn't really start. We even tried using some starter fluid but it still wont start. Any ideas????? It has the stock duraspark II ignition system. Is is possilbe for something to go out in the ignition system and still allow the engine to spark but not produce enough volts to ignite the fuel???? Thanks much.
