When temps get down in low 30s my 7.3 won't start. Sure fire way to get it to go is to slightly preasureize the fuel tank. Fires up and runs a little rough for a minute or so while blowing white smoke. Seems like there is a restriction in the tank outlet or does someone have another idea. So far this only happens when parked overnight so I haven't been stranded yet... but that day is coming for sure. HELP!!
sounds like the fuel is gelling in the lines and by pressurizing the tank your forcing un-gelled fuel to the pump. Just start putting some additives in with each tank and you shouldnt have to do this anymore.
Diesel Kleen's white bottle should help you with this. Might want to check your fuel filter, batteries (and battery connection), and Glow Plug Relay, as these are all contributing factors to a hard start, as well as the gelled fuel as ^^^ kyle has said.
Well the good only lasted 2 days and then back to no starting. Did FINALLY find the block heater and since I started plugging in fires first try every time even when cold.
