Another common problem experienced by 626 owners is a crank but no start issue. This occurs when the engine cranks but fails to start and run independently. This issue can be caused by various factors, including a faulty fuel pump, clogged fuel filter, failed ignition coil, or a malfunctioning crankshaft position sensor.

Additionally, issues with the timing belt or camshaft position sensor can also cause this problem. Model years from 1993 to 2002 suffer from this issue, with repairs costing up to $1000. Therefore, it’s important to have a qualified mechanic perform a diagnostic assessment of the vehicle to identify and resolve the root cause of the problem.

One other common problem experienced by Mazda 626 owners is a failure of the intake manifold gasket, which can result in a vacuum leak and rough idle. If the gasket fails, air can leak into the system, causing rough idle and other issues, such as reduced power or acceleration. The cost to repair these issues ranges from $502-575.

Some common causes of intake manifold gasket failure include age, heat, and pressure. Suppose you suspect a vacuum leak or notice a rough idle in your Mazda 626. In that case, it’s important to have the intake manifold gasket inspected by a qualified mechanic to diagnose and resolve the problem before it causes further damage to the engine.

In conclusion, while the 626 is a good value, there are many issues. These issues include transmission failure, crank but no start problems, and intake manifold gasket failure. Left unaddressed, these problems can lead to significant damage to other components in the vehicle and costly repairs. Therefore, it’s essential to have any used Mazda 626 you’re considering inspected by a qualified mechanic to identify and address these issues before making a purchase.
