2007 mazda 3 2.3 hatchback, 148000 miles. auto. I have a no crank issue. can crank from relay and starter but getting no spark. No security light rapid flashing or immobilizer codes but i feel like the immobiliser is on because of the symptoms. Have two keys with one fob that still works. Have a solus pro and getting a ucode for can bus and a code for losing com with abs. i also have no com but no code for the PJB, airbag module and temp control module. I can use my test light to provide a ground to the starter relay control out side pin and it will crank with the key but still no spark. I changed battery cables, cleaned all grounds ,PITA!!.. I caused this when attempting to figure out why the second and new tcm was losing com every other day. Hoping i fixed by actually providing fresh grounds but taking apart connectors and cleaning pins gave me one start that filled my garage with white smoke from the car then the no crank condition. please any ideas?
