The gap will increase during use as metal is lost from the electrode surfaces. Dual platinum or iridium plugs grow their gap much more slowly than the traditional plugs do.
The gap can be decreased, in rare cases, if a piston or foreign object in the combustion chamber comes into contact with a plug's side electrode.

Why won't my 1993 Mitsubishi 3000gt start Replaced ECU fuel pump and still not running.?
well the real question is do you have spark are you getting fuel? well you can take and roll the motor oveer and then pull the spark plug. if the spark plug is wet you don't have spark if the spark plug is dry you have spark that's the easiest way to take a look. the motor need three thing to run fuel oxygen and spark. DO NOT ROLL THE MOTOR OVER WITH THE SPARK PLUG OUT OF THE CYLINDER YOU WILL MORE THAN LIKELY LIGHT THE FUEL THATS PUSHED OUT OF THE MOTOR IN THE COMPRESSION STAGE. when you find out if the motors getting fuel and not spark it could be your crank sensor which tells the motor when to ignite the spark plug to cause your explosion which makes the motor run. i hope this was helpful.

If the engine jumped time could it cause the spark plugs not to fire on a 1966 Valiant?
You will still have spark, car will try to start or backfire. If no spark at all the plugs see if you have GOOD spark from coil. If coil is working then you will find the problem in between the coil and the plugs, probably a distributor component issue. The ballast resister is a possible cause also.
