Got a 94 GTS this weekend... changed the gas as it had been sitting and checked the oil. Started first try and ran amazing... didnt pin it ever but had been pulling a wakeskate for a couple hours (never past 2/3 throttle). Was idling waiting for a person to grab the rope when the idle went really low, rumbled for a second then died. Tried to start it again and it started and died after 5 seconds. After that it would only make one loud click and not turn over when the ignition was pressed. Gas is fine, oil is fine. Tried to jump start it (which i now know is a big mistake). Any tips? Help? Hoping i didnt blow the engine.
