2002 Mazda 626 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2002 Mazda 626

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.

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.

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.
