Did you check the harness down to the crank sensor? These have been known to break right at the connector, they look good but the wires inside are broken. If that checks good then you need to find out if it is spark or fuel related, a little starter spray down the intake tube will tell you that, if its fuel it will start and run briefly, if it is spark it won't

P0336 CHEVROLET - Crankshaft Position Sensor 'A' Circuit Range/Performance.... Possible causes - Faulty crankshaft position sensor - Crankshaft position sensor harness is open or shorted - Crankshaft position sensor circuit poor electrical connection - Signal plate may be damage - Starter motor may be faulty - Starting system circuit - Dead or weak battery..... The crankshaft position sensor (POS) signal is not detected by the Powertrain Control Module (PCM) during the first few seconds of engine cranking... Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light) - Engine Cranks but Does Not Start - Lack/Loss of Power - Engine Stall... P0336 Chevrolet Description... The Crankshaft Position Sensor (CKP) also known as the crank position sensor is an electronic device used in an engine to record the rate at which the crankshaft is spinning. This information is used by the Powertrain Control Module (PCM) to control ignition and fuel injection. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor. When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change.
