COLD START NIGHTMARES

[stroke me 70]

Hey can someone clue me in on a recent problem with my stroker ? when the truck sits for 8hrs or so while I work second shift , it does;nt want to start when I come out at 12am.. iun the cold (7degrees) last night to be precise... Its a 2000 f-350 7.3 dually , has 100,508 miles on it... could it be the glow-plugs ? It will fire when there cycled but stahls right away , after about 15 cycles and start-ups it will diesel over and throw the tuck from side-to-side until the computer tells it to up the rpm's....

Glow plugs and your glow plug relay is a very goo place to start with the no start issue.

my 99 acts the same way. I am going to change the oil over to 5W-40 and see if that helps anything.

How does it run after its started?

start with the glow plug relay its easy to test and they fail way more often than glow plugs

[tonypagnano]

where can i find a picture of the glow plug relay, i dont have a manual for my truck yet i need to get one but im starting to learn alot. Is it the brown solenoid looking thing on the top of the motor next to the fuel filter? (late 99)

[vitalidle]

Yes it is. Have a look at this writeupTroubleshooting GPR & GP's

yep when your looking there theres 2 of them its the rear one if you replace it use the big stanadyne one

My parents 99 did the exact same thing as what your describing. The truck would take about 10-15 cycles and then chug like no tomorrow. Ended up being the GP relay. I forgot to plug mine in the other night and the temp went down to around 10-15 below and i just cycled my GP's 2 times and she fired right up. Shook a little then smoothed right out. I am also still running 15/40 wating for my change time, then i'm gonna try 5/40 syn.
