Went to start the Blazer and my glow plugs dont work! No glow plugs=no start. Its been converted to a push button, no "wait" light. Its an old ARMY CUCV so its a 24V system, when the glow plugs work you can see the voltage drop on the gauge. The solinoid works OK, but no voltage drop, and no glow plugs, is there a fuse or something I am missing? Im stumped, and its my DD so I kinda need it fixed soon! 84 K5 Blazer 6.2L diesel TH400/NP208 4" lift on 35" Pro Comp Xtremes 4:10 gears with detroit lockers front & rear. I just put new glow plugs and injectors in it and had the injector pump rebuilt.
