Often, the glow plugs on a diesel engine are overlooked, until they are malfunctioning. As a diesel pickup owner, it is important that you understand the signs of failing glow plugs and that you act quickly to get them replaced. The longer you wait to replace faulty glow plugs, the more damage you will have to deal with.

If a glow plug fails, your pickups’ combustion chamber will not receive the heat that it needs to ignite. On warmer days, you may be able to achieve ignition after multiple startup attempts. But, in the colder winter temperatures, it is very unlikely that your engine will ignite at all if you have faulty glow plugs.
