Asked by Jan 01, 2016 at 10:34 PM about the 2000 Chevrolet Blazer

Question type: Maintenance & Repair

After testing a getting good spark at the top post
of the coil I'm guessing the culprit to be the ECM
?? HOW DO I TEST THE ECM AND DO I HAVE TO
PULL THE DISTRIBUTOR TO REPLACE IT ??
DOES THE COIL HAVING GOOD SPARK MEAN
THAT THE CAM POSITION SENSOR IS GOOD ??

A code checker is the best way to test the ECM, I have seen these rigs run even with the sensor unplugged, so no it does not mean that it is good. What is your actual problem?
