I have a 4.3L EFI engine that will not idle. Actually, it refuses to run at all below about 1200rpm. Whenever the engine drops below 1200 (approx), there is one long beep (same beep heard upon turning the key on initially), and then the engine dies. Above 1200, I have no issues whatsoever; good smooth power. I replaced the IAC thinking that was of course my problem, but to no avail. Money down the drain...again! I took the flame arrester off and started the boat this afternoon, and watched the injectors behavior. Immediately after the beep (actually during, the beep is long), the injectors stop spraying, and engine dies. replaced fuel filter today, no change. I believe it has to be electrical, but do not have enogh knowledge in this area. I have spent the past few hours searching this site as well as google, and have had no luck. Anybody know if this is more common than I have found? Can a sensor do this? All gauges read normal when this happens.
Any help greatly appreciated!!!!!!:huh:
