^^^This guy is leading you down the right path, do the test light test on the glowplug relay.

 

ok thanks is there anything else that could be wrong with it???

 

but isn't there a silenoid instead of a relay???

 

Bad fuel. But like said, smoke means there is fuel but if it is low in cetane, it may not light the fire

 

Same thing. one is just bigger. but yes you are right it is a solenoid. There should be four posts total on the solenoid, two small two large. One large will have power all the time, one small will be ground the other positive, one the small curcit is energized, the other large post will have power.

 

depending on the location the truck was sold in there could be a cold weather package on the truck. this would include the manifold heater. it has a controller that looks similar to the glow plug controller but it is taller. they are beside each other so make sure to test the shorter solenoid. that is the one for the glow plugs

 

ok i fixed the problem and it was the glow plug silenoid

now when she started up the motor makes a serious ticking sound and it gets worse when i rev it up a little could it be lifters or rocker arms???
its definately not a knocking sound its more of a ticking and its up top some where

 

fuel knock? or valve noise?

 

it really sounds like a lifter or a rocker arm ticking sound...
is there any kind of problem with the valvetrain that you have ever heard of before or do you think that it could be something else???

 

nothing common on those. they were pretty bulletproof. hard to tell without actually hearing it.
