My son has a 1997 Mazda 626 which has no spark comming from the distributor to the spark plugs. I already replaced the distributor which has the crankshaft position sensor and the camshaft position sensor built into it. I have the Haynes manual and looked at the electrical and found that it has a knock sensor according to the manual will creat the AC output voltage. It suppose to have a resistance reading of 560 ohms, I can not measure anything, if it is an open circuit will this not allow for any spark. If this is not the problem is it the powertrain control module? Can the module be repaired or reprogrammed?
