Why won't my 2002 blazer start it trun over just won't start was running good that I shut it off an hasn't start back up an has milky oil

 

Milky oil is caused by condensation, or coolant in the oil. The lower intake manifold gaskets leak coolant around the coolant passages between the intake manifold and the cylinder heads, (very common problem on this engine). This will not cause the no-start, but it will cause damage to the bearings in the engine, and needs to be repaired ASAP.


As for the no-start, first step is to check the fuel delivery system. This thread explains: https://blazerforum.com/forum/2nd-ge...eakdown-88305/
