Vids of Your cold start?

[Farmertom390]

I am really hating winter lately but before I started my truck up today for the first time in forever i figured I would take a quick video. It started up way faster than I figured it would. Does anyone else have vids of your truck starting up?

Typically a cold/sticky ICP sensor or IPR valve.

Try starting the rig with the ICP unplugged. If it doesnt romp, then you have a bad sensor. If it still romps, you probably have a bad/sticky IPR

The romps are usually caused by running 15w40 in extreme cold temps. Switch to a 15w40 or 5w40 synthetic. The romps will go away

my dad owns a 99" sd 7.3 (one of his company trucks)
he told me today that it wouldnt start
so i said...
pluged in? yes
wait to start? yes
then i said has it had trouble starting for a while now? no just this past week
so i said lets go look at it and it would turn over and it turns over quick enough and sounds like its trying to fire but dosent fire
so i said lets try the gpr
so i went to napa-closed
then autozone and they said whats a gpr? and i showed it to him and he said the starter selinoid and i said ?????????????????
and he got one-duralast looked simalar but it was olny 10 bucks and i was again like ????????????????????
so dad said yep!!! thats it so i changed it and nothin changed
called dads mechanic and he said the 7.3's dont have a gpr
he said they dont even have gp's, said they have some ordeal under the intake that dose somethan or another-i didnt pay much atention after he said 7.3's=no gp's
and i just pretty much just hung up on him
but when you turn the key on (idk what it is) there is a l black cylnder looking thing with a 1/4" hose or 2 comeing off of it that clicks real fast while the key is on
sorry for the hijack

Thats what i figured. Do you have a technical explanation as to why 15w-40 makes it do that?

Not to technical. 5w40 has a better cold temp flow rate than 15w40.

heres a test for you. If you have a spare quart of 15w40 laying around. If its 10 degrees or colder Leave it outside overnight. Try to pour it out of the jug in the morning. It pours very slow and is very thick
