2002 Mazda 626 ProblemsTransmission Failure Common
Premature automatic transmission failure is common. Diagnoses of the fault will be necessary to determine if repair or replacement is the proper repair.
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.
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.
