I have been replacing my glow plugs two at a time every pay day from the start of last month.. now I'm having them go out .... what could be making them go out so fast? Is there a sensor that controls how long the glow plugs preheats? 2 days ago it had 3 glow plugs go out..tested all of them with test light. Norm I would have to replace them year/year and a half..they are the zd 9's.... Info on truck. 93 f250 non turbo...4x4 about 215000 for miles.... injectors,injector pump and glow plug controller replaced about 2 1/2 years ago right when the cold snap happens.I Replace the glow plug harnesses to the make your own harnesses last winter. I do run a 50/50 mix of wmo and diesel for the last 2 years. When glow plugs are out they have a sooty look to them.I also run the block heater from 12am-6am and then from 2pm-5pm. Thanks Joe
