Re: 99 blazer cranking problem
What is liter size of engine? If you have the spider type fuel system, those fuel systems are known for problems, Sticking fuel poppets for one. Check fuel pressure, also.
Can you check fuel injector pulse? Any applicable trouble codes? Did you visually check for spark at the spark plugs when problem is ongoing? Even a new battery will run down if you crank it enough without starting.
