I have a 79 gmc jimmy with a 350, the last time I started it up was around Christmas (I'm away from the truck for college). There weren't any problems then, just had to crank it and it fired right up. I tried starting it today and it turned over maybe 1/4 of a complete cycle and then there was just a clicking sound, no cranking or anything. What could this be? I need to get the truck to my new apartment so I can get it ready for summer. Thanks for any help!
