No, Glow Plugs are used to help start a cold engine. They can also be used for emisions (cold start up).

Do the glow plugs cycle after engine is running?

No they do not, After engine is running there is no need for glow plugs because there is enough heat in the cylinders to warm the fuel. The glow plugs are designed to heat up the cold diesel fuel on start up only. Actually glow plugs will cycle briefly after engine start up to keep the cold fuel from bringing down cyl temp until the engine warms up. A power stroke will keep glow plugs on for up to 180 sec. A chev will run considerably less I believe.

Where are glow plugs on a Kia Sedona?

Kia Sedona 2.0 CRDI does not have glow plugs. It does not have glow plugs it uses compression to start. It might be the heater box? You can try priming the fuel before you turn it over by squeezing the baloon in the front of the engine compartment when you squeeze it it pushes the fuel up for starting.This worked for me but the fault code showed it was the fuel pump. It wasn't it turned out to be a leaking injector. Needed to change 2 then it starts fine now. It was not the fuel pump at all.
