I have a 1994 Mazda DX 1.8. One day while driving car was hesitating off and on from a stop. After a while quit hesitating. Then, after parking and restarting, went for a drive and the car just stopped - died and would not start.
After towing home and testing, there was NO spark, replaced coil - no spark, replaced coil again - no spark, replaced distributor - no spark, replaced TPS, no spark. Just double-checked, gets juice to positive side of coil and juice to positive of distributor. Still NO spark. Tried jumping ten and ground in diagnosis module to get codes, didn't seem to work. (Engine light does NOT come on when ignition is in the ON position) I am stumped. What in the world could it be??
the Coil (Twice, new one)
the TPS (new)
the main relay (new)
the ECU (twice, used)
the distributor with cap and rotor (new).
