2001 Buick LeSabre mileage: 31,000. Last time I drove my car, the service engine soon light came on, it also seemed to hesitate some. Now the car won't start. It just turns over. I disconnected the battery so I lost any info stored in the ECM. It has a strong spark and good gas pressure. I am sure it is a timing issue. Can you tell me how I can check individual sensors and modules in the timing system?

Disconnecting the battery will erase the fault codes from the ECM. However, hooking the battery back up and turning the key on will reset “hard codes.” This information should pinpoint your malfunctioning component.
