I have a 1988 Allegro. I haven't used it much this summer and haven't kept up with starting it to keep the house batteries charged. I went out today to crank it up and charge up the batteries. Of course the house batteries were dead, but the engine started up right away. It ran for about 10 minutes and then quit. I attempted to start it again, and it would turn over but not start, like it was flooded. I also heard a clicking noise in the rear under the floor. The noise stopped when I turned off the ignition. I had my wife come out and turn the key without turning the engine over and could still hear the clicking noise underneath. It would stop in less than a minute. I hooked up a battery charger to the house batteries and charged them enough to start the generator, which started and ran fine. In fact it's still running and continuing to charge the batteries. So the question is, why won't the engine start? Is it a fuel pump thing? Any ideas would be greatly appreciated.
