Go to the glow plug controler on back of engine.
Check for power to it and if it is powering the glow plugs.

Does the wait light on dash work as it should?

sorry was sent out of town
ok turns out someone that i bought truck from tryed to tap in main power line think he was trying to bypass glow plug controller
i have it wire to where there is power and glow plugs come on and truck starts but after truck is started the glow plug light come back on ... does that mean the glow plugs are are turning back on while its running

When and How long does it come back on?
Does it go off after truck warms up as it should?
