Default 1999 4.3 blazer Engine crank then progressed to not starting

Hi everyone,

My grandfather has a 1999 blazer 4.3 liter v 6 4 door 4x4 that had a crank problem. It would crank a lot before starting but now will not start at all unless putting gas down the intake. he replaced the mass airflow sensor and the spark plugs to see if anything would help but nothing seems to help. Do you any suggestions?
