The car 1981 Eagle Summit, just up and quite running, the battery is fine, the starter works fine, engine spins over fine, if you hold the throttle to the floor the car will light off for about 3-5 seconds then quit, and the cycle starts all over again. The under hood fuses and circuit breakers are fine visually, can not even think what the problem might be. Help
