2003 Chevrolet Blazer 4.3L V6. Replaced crankshaft sensor, truck won't turn over.
Truck over heated, replaced camshaft
sensor earlier. Then it would not turn over
just replaced crankshaft sensor.
Your cam or crank sensor will not stop your car from cranking over, check your battery and starter first, maybe since you over heated it the head gasket went and you have a cylinder full of antifreeze its called a hydolock
Or the starter is burned out from being overheated. HTH. -Jim
