Default Blazer starts randomly
Recently replaced intake manifold gasket (4.3). Started fine ran fine after repair. Turned it over the next morning, the engine shakes and sputters and doesn't start. I tried til it did start. Ran fine. Now it starts randomly. Scanned it and pulled a P1345 code. Looks like the Crankcase sensor. Any other ideas?
