If the complaint was Engine Cranks But Will Not Run, you may set DTC P0336 when attempting to start the engine more than 15 times, and ignition is not turned OFF between attempts.
The following conditions may cause this DTC to set: Poor connection or poor terminal tension at the sensor, crankshaft reluctor wheel damage or improper installation, excessive air gap between CKP sensor and reluctor wheel, engine running out of fuel, or foreign material passing between sensor and reluctor wheel.
Excess crankshaft end play causes the CKP sensor reluctor wheel to move out of alignment with the CKP sensor. This could result in any one of the following: A no start, a start and stall or erratic performance.
For an intermittent, refer to INTERMITTENTS in TROUBLE SHOOTING - NO CODES - 2.2L ALERO, CAVALIER, GRAND AM & SUNFIRE - GASOLINE article.
