1993 Mazda MPV Problems
If the engine cranks but won't start, the fault may be internal to the distributor. Diagnosis will show no spark and trouble codes for the crankshaft position sensor (CKP) or the camshaft position sensor (CMP). Our technicians recommend replacement of the complete distributor assembly if these conditions occur.
A loud ticking noise (hydraulic valve lifter noise) may be heard from the top of the engine, particularly when the engine is still cold. The noise may occur more frequently on higher mileage vehicles; Hydraulic valve lash adjusters may need to be replaced to correct this issue. Following the maintenance schedule for oil changes will also help prevent a recurrence of the noise.
If a rumbling noise is heard from the engine, along with a possible loss in power, it may be caused by a collapsed hydraulic timing belt tensioner creating excessive cam backlash. Our technicians recommend replacing the timing belt and water pump at the same time, if they have not been recently replaced.
A leaking coolant pump can leak onto the timing belt and cause it to tear. Our technicians recommend replacing the coolant pump and timing belt every 60,000 miles to help avoid this problem. It is also important to follow the fill procedure for coolant on this engine to avoid problems.
