2000 chevy blazer 4.3
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?
