Mazda Repair: 2002 Mazda 626 doesnt start, spark plug wires, mazda 626
QuestionMy car does not start. It is getting fuel but seems to have a weak spark. The sensors have been tested with a meter and appear to read fine. I have been told that these reading don't really mean anything though.
Answera weak spark can be a number of contibuters frist check te plugs themselfs for proper gapping and cardon deposits or signs of needing replacement if the plugs look ok check the spark plug wires ( if they have any) you can do this by misting the wires with water from a spray bottle if the engine stumbles and seems it wants to die the wires are arcing and need replacement. and worse case is that the coil pack is gone i suggest that if you susect a bad coil you have it tested my and automotive shop it's best test with special test equipment however there is individual tests of the different components in the coil.
