On the 1993-1997 Mazda 626 2.0L FS I4, the 626's distributor assembly contains the ignition coil and hall effect sensor, both of which fail prematurely. The distributor is mounted on the rear of the cylinder head where it is exposed to engine heat. Internal components fail between 80,000-120,000 miles causing intermittent no-start, misfires, and stalling. The failure is often intermittent, making diagnosis difficult.
Replace the complete distributor assembly ($200-$400). Replacing only the cap and rotor will not fix internal electronic failures. A remanufactured distributor from Cardone is a reliable budget option. Verify the coil wire resistance and check for spark at each cylinder before condemning the distributor. The ignition control module (ICM) should also be tested, as it can cause similar symptoms.
