I JUST TRIED TO START MY 97 CHEVY BLAZER AFTER SITTING UP FOR ABOUT 2 YEARS AND IT WON’T TURN OVER. I PUT A NEW BATTERY IN IT AND IT HAS PLENTY OF GAS. WAS RUNNING FINE WHEN IT PARKED.
Clean, or replace, the battery cables. Corrosion on them won’t let enough juice get through.
You could also try taking the spark plugs out and handcracking the engine to see it it turns over.
Hey thanks for the great ideas. it looks like a fuel sending problem
