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.Google+

Our Mazda MPV randomly won't start, it cranks but won't start or it starts for 1-2 seconds and quits and then won't start again.

I replaced the distributor and did fix problem for a day. Next morning I drove the van to the same service station where it broke down and would not crank the week before and it refused to start again. The distance is less then one mile. There seems to be a correlation between engine temperature and it not starting.(Cool = won't crank back up) Now I let the engine completely warm up before shutting it down and it re-cranks every time.

Car was running like normal then all of a sudden it died as if it ran out of gas. Checked fuel pump and filter they ok. Shut off engine and something seemed like it was still turning (Radiator Cooling Fan?). After tried starting...cranks but dues not run. Checked coil by taking wire and holding metal opened end close to metal grounded. No sparks.
