Order of inspection
P0338 Crankshaft Position Sensor A Circuit High High
The P0338 code means the signal from crankshaft position sensor A is higher than the computer expects. Without a clean crankshaft signal there is no spark and no injection, so the engine can be hard to start or can stall. An open signal circuit or a broken sensor ground is the usual reason.
