SOLVED: Tested the GPs and found 3 of the 5 brand new Autolite glow plugs (installed the week before this happend) were completely dead and a 4th was reading way too much resistance. The fuel was definitely gelled, I could see it in the clear fuel line and pumping the primer pump wouldnt move the fuel, but who knows if it would have started or not had all 5 glow plugs been working. I put in the old glow plugs that i luckily saved, and it fired right up, instantly. NEVER NEVER NEVER NEVER will i ever purchase anything with the Autolite brand name again, period. The Bosche glow plugs that were in there before look like they are 20 years old, and they still work. It is beyond belief that 4 out of 5 brand new glow plugs could go dead in a single week of use, Autolite should be ashamed of themselves for even having that product on the shelf. Lesson learned, brand names do matter sometimes and never assume something you just replaced is actually working just cause its new... And thanks to all of you for your suggestions.


I live in DC and it got down near zero last night, 10 deg this morning. I last filled up in Sept and had not driven it until last week when I finally got around to fixing the heater... Drove it yesterday, no issues, went to start it this morning, no go, got under the hood and pumped the primer pump, diesel not moving in the clear line that goes to the spin on fuel filter. I can clearly see it is gelled. Slowly poured a gallon of boiling water on the IP, filter, and fuel lines just now, still no go. Anyone have any experience here on this? Do I need to change the spin on filter now, maybe light a bonfire under the engine. Never even crossed my mind that it only had "summer blend" in it...
