How do you clean a glow plug in a diesel engine?
Pull the glow plug wire out of the engine. You will be cleaning all of the plugs, but you should start and work on only one plug at a time. Pull the top of the plug wire off the top of the engine. You may need to twist the plug wire gently back and forth while you are pulling up on it, but it should come right out.

What should I do if my glow plug is dirty?
Clean each electrical contact and nut. Similar to battery contacts, glow plug wires can become dirty, which can result in a poor electrical connection. Use reamer and ream the glow plug hole for each glow plug. This is just to clean out the glow plug hole, so ream only long enough to remove any buildup.
Is the glow plug on a power stroke engine working?
The Power Stroke Diesel engines rely heavily on the glow plug system. This time of year, when temperatures get low, it can be especially critical that the glow plug system is working properly. In this article, we discuss the important of glow plug operation and how to diagnose and fix Power Stroke glow plug faults.
What should I do if my glow plug is not working?
But the PCM continues to provide power to the glow plugs for as long as 180 seconds to pre-heat the combustion chamber—even though the “wait” light is off. If you suspect a problem with the glow plug system, start here: 2.At the glow plug connector (GPC) on the right side valve cover, check for battery voltage on the large black/yellow wire.
When do glow plugs on diesel engines wear out?

How do you test a glow plug in an engine?
Testing Glow Plugs in the Engine Grab a multimeter. Set your multimeter to ohms. Find resistance value of your multimeter. Test the voltage of the battery. Locate the glow plugs. Remove the caps or connectors to the glow plugs. Clip the multimeter’s negative lead to a ground point in the engine.
How does the California glow plug system work?
The California system operates in a similar fashion but uses a module to switch power to the glow plugs instead of a relay. The output from the module is different than for the 49-state version. It has one output wire for each cylinder.
