How to test a 1988 mazda 323 electronic ignition module and replace it, the car just suddenly died. It has new rotor, cap and plug wires. New plugs too.
I had that problem on my 1991 Mazda MX6. Indeed, it was the ignition module. As I recall, I was able to test the old one at an "Auto Zone" store near me. The problem was, however, that it tested "good" there and so I had the dilemma of trusting my instincts which told me it was bad, since I had eliminated other logical alternatives (as it appears you have as well). I strongly believed that the failure was intermittent/heat related, as I was in fact able to drive the car the next day from the parking lot I had left it at, back to my house (in order to remove the module in the convenience of my own driveway) to take it to be tested. Another clue that it was a heat-related intermittency, was that the clowns who put it in at the mazda plant had forgotten to put any heat-sink grease on the module prior to installing it...bad news. So I made the decision to risk the $98 on the new module (non-refundable, on electrical parts) and buy the new module in spite of the old one testing "good". I installed the new module, WITH the included heat-sink grease...and drove that car for another 75,000 miles, with no more ignition troubles!
