I would suspect that your attitude and language would have offended said truck... There are a multitude of fixes for the glow plug system and they are in the archives of several of the lists... All that you have to do is actuate the glow plug relay manually by means of a momentary contact switch.. However, if you have already tried everything, that means that you have done that too.. Of course the plugs may be fried, but you have probably taken them out and checked their resistance individually on the bench to be sure they are OK...Fuel getting to the cylinders? etc etc etc...then, lastly... in the manuals which all MV owners should have for their trucks, there is a wonderful section on troubleshooting the glow plug system... the Manuals are the TM 9-2320-289 series...
