I have a 1996 Mazda 626 DX 4-cyl. which on occasion will not start. It seems to occur when it sits over the weekend. I have changed the fuel filter hoping that was the problem, but it did it again this AM. It could be a sensor, but I don't know where to start. After it does start it runs fine, except a possible hesitation that is so minor that I cannot be sure that is what it is.

Suggested Repair

Check when the last tune-up was done and inspect and test the coolant temperature sensor.

Conversation Summary

The owner of a 1996 Mazda 626 DX reports an occasional no-start after the car sits, especially over a weekend. Replacing the fuel filter did not fix it, and the engine runs fine once started, with only a possible slight hesitation. A user asked whether ECM codes were stored, but none were confirmed. An expert asked about the last tune-up and recommended inspecting and testing the coolant temperature sensor. The owner planned to follow those steps, but no results or confirmed repair were reported.
