My first problem is that I love this car. I have had very few problems between service intervals and it's easy to work on.
1992 Mazda Protege SOHC DX, about 180,000 miles, real close to needing engine rebuild but doesn't burn oil.
I drove it to a 4H meeting in the morning (5 miles), and it wouldn't start 2 hours later. Tried fuel starter fluid at the throttle plate, not even a bump (engine turns from starter only). Let it cool down, nothing. Had it towed home.
Checked for spark at no. 1 spark plug, nothing. Checked for spark at the igntition coil, nothing. Igniton coil meets spec (1ohm at primary, 16Kohm at secondary through the ignition wire).
I had no way of checking the ignition module. Mazda dealership only tests it in the car and NAPA didn't have a cross-reference for the Protege igniters in their tester manual.
Hey, the CEL is on! Set up for reading codes at the diagnostic plug by jumping TEN to GND. All accessories OFF, transmission in neutral, ignition switch to position ON. CEL is on, but not blinking any codes. Checked battery, 12.93Vdc using Fluke DMM. Reset jumper (22ga solid copper wire) in diagnostic plug. Tried again. CEL is on, but not blinking any codes.
Time to try clearing the CEL. Disconnected the negative battery terminal and pressed the brake for more than five seconds, basically following the procedure in the Haynes manual. Reconnected the neg. battery terminal.
Turned ignition switch to ON, CEL comes on but does not go off. I haven't tried starting the car, so I don't see how any new codes could have been entered or saved. Tried to start the car. It wouldn't start, same as it was four days ago.
I was hoping for a code 02, replace the distributor, and drive off!
Is my engine control module bricked?!
