12 valve won't start
#31
Here is some quick fixes for people with gelled diesels ive been all over the country traveling on pipelines and running diesel trucks, from mountains to the cold tundras i dont plug my 12 valve in unless its below about 10deg., but if i know ill be in a cold place for awhile around 0deg. i retard my timing close to factory to help starting, also if it gells on u dump methanol in the fuel tank not the fuel filter incase yur fuel supply line gelled, methanol is thinner than diesel and will go straight to bottom, another thing is spraying either in a soda bottle until u get some liquid in it and dumping it into the fuel filter and screwing it back on....btw i live in Mo. to but im hardly here usually somewheres colder

With the grid heater functioning you'll cause the intake manifold to explode in your face causing serious injuries. These trucks shouldnt need ANY starting fluids if the fuel system is working correctly. Anyone that tells you that ether or starting fluids are a good idea is a dummy (just to make this clear, if they dont mention grid heaters their dummies) Modern diesels should only see ether in a controlled diagnoses enviroment by a trained tech. If it wont start, Bleed the fuel system, verify fuel pressure and flow and then think about spraying it.
Unless of course we're talking low compression pullers or race trucks.
Another thought about this thread has anyone looked at the diesel blends for the US? If you look at the numbers you'll see that it rarely get's cold enough in most areas to gel or wax. A good additive would completely eliminate the concern of gelling. We see more waxing that stops up fuel filters in this area.

Verify Lift pump pressure and flow. It would be best to delete the fuel heater, install a new rubber loop line to the pump and verify the rubber and steel line is in good shape. If you pressurize and see no leaks the lines are fine. The fuel heat can allow enough air to enter that the truck wont ever prime. Sounds like the lift pumps bad. 30 minute pie job!

New lift pump didn't fix the problem?
If not and you are getting fuel to the injectors, I would check the pump timing it may have slipped and would cause the problems you mentioned.
Also get rid of the fuel heater and replace the lift pump to fuel heater line, I've got rid of mine last fall and the truck starts and runs perfect in -40c (-22f)
