If the engine cranks but does not start, it may be caused by a tripped inertia switch. Switch the key to "ON" and the fuel pump should be heard running for a second or two. Listen at the gas filler if necessary. If you do not hear the pump the inertia switch should be reset, it will "click" when it is reset.

2002 Mazda 626 Problems
Misfires under load (acceleration) can be caused by leaky spark plug boots. When a spark plug boot leaks, it allows the spark to arc, or jump, to the cylinder head. If evidence of arcing can be seen on the inside of the spark plug boot, new spark plug wires will be needed.
The passages for the Exhaust Gas Recirculation (EGR) system can become restricted or clogged causing the Check Engine Light to illuminate. The EGR valve will need to be inspected and the passages cleaned.
If the engine cranks but will not start, it may be due a failed distributor. In the diagnosis, it may be discovered that the Electronic Engine Control (EEC) Unit is the cause if ignition spark is restored after disconnecting the Spark Output (SPOUT) Connector.
Vehicles with a V6 engine may develop an engine misfire under load (acceleration). This can be caused by a valve cover gasket leaking oil into a spark plug well, shorting the spark plug to the cylinder head. To repair this concern, the valve cover needs to be resealed and the spark plugs and wires should be replaced.

2002 Mazda 626 Reviews
This is a 2002 Mazda 626 LX V6 with Automatic Transmission. Bought car used (former rental). Owned it for 8 years so far, still going strong. Regular oil change and 30K, 60K maintenance... only repair bill was to recharge the freon last year - must've leaked out from lack of use through the years. Car indicates needing premium gas but have been using regular with no problems. Did not notice any gain in MPG when using premium. Plan to keep this car for another 2-5 years.
