hell get a can of starting fluid to fire it up but be carefull you don't over do it cause your truck could do a run away and unless its a manual transmission where u can dump the clutch and kill it you could blow the motor.

you can also put sum additive in your fuel tank if it is gelled up so it wont happen again in the future.

8 degrees here the other morning and mine wasn't plugged in, so just for ***** and giggles I tried it. Cycled the grid heaters twice and it fired right up. No oil pressure though untill I brought the rpm's up a little, I guess 15w40 is a little thick for those temps.

whats so horrible about ether? some 3.9 and 5.9 applications had ether injectors installed from the factory. just dont spray it on a hot grid heater. pull the little wires off the heater solenoids on the fender so they dont come on. if ur paranoid about a runaway problem take the intercooler pipe connector off at the intake so the ether will go right in and not get built up in the intercooler and then stir up any oil that may be laying in there. definitely dont spray any liquid like wd40 in the turbo. that will make it run away cause it wont even make it to the engine until its running and then will come all at once when the rpm is high enough.

btw, if u wanna see proof of what happens when u put non vaporizing things like wd40 in the turbo, come to newburg and ill show you a customers 24 valve i have torn down right now cause he put liquid in the turbo and it ran away after it started and messed up the cam and crank gears.
