I have a 91 GMC sierra 2500 model. It use to run good. Until I park the car at my mom house and haven't start like 3 or more month. and now it not even crankin or starting at all. I replace the spark plug, check the battery and they good, but no crank. I was thinking maybe it was the alternator. or the battery. The auto store guy told me to try the carb. spraying can, and see if it work. But I think that not the problem. Can anyone help me? please. Other time when I drive the truck to my friend house and try to drive back home the car won't start, try jump start couple of times and about 1hrs later it start. I also check with the Tires LEswab for battery check up they said they battery are good. Any suggestion or things I need to fix my truck again? Also if you have the alternator can you let me know I buy it from you. thank.

You have a weak battery, probably flooded the engine it before you went to jump start it at a friends house, if the truck runs eventually after you boost the car then its clearly not the starter or the alternator.

Have the battery charged up or put a jump on it...if still no crank, it could be a bad starter or neutral safety switch or ignition switch. Try moving the shifter to neutral or jiggle it a little when trying to start. If no luck, you'll have to diagnose if you're getting power to the starter. Could also be loose or corroded battery cables.
