2004 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.
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.
