My OBS started this morning in 25* cold, easier than ANY of my other diesels EVER have... my TDI was the best starting cold-starter I've ever seen until I got this OBS... what gives? My NBS would be cranky with anything under 50*... and nearly ALWAYS needed the GP's cycled. With my new OBS, the GP's only need to be cycled once for the first cold-start, and the rest of the day they are optional.

What the?!

 

Your SD probably needed glow plugs and a relay.

 

The thing that kills me is, my VW diesel is the easiest starting cold-weather diesel i've ever seen in my life, and powerstrokes are notorious for being hard-starters due to being HEUI injection, so they dont like the cold.

This morning it was about 10*f out, and my psd started prettttty easy with 1 gp cycle. My vw took 1 gp cycle, and I had to crank for nearly 15seconds, while applying throttle!

 

Mine starts right up too at 10*... Nothing out of the ordinary...

There are a lot of players involved in starting a cold diesel... If one of those were not doing their job, then that was the cause of your hard start on the SD...

Don't sweat this... Be happy that it starts.

 

I'm actually super pumped it starts so good. Granted, it does have new GP's in it.. I just cant believe how easily the supposed hard-starter out of the big-3 is starting so easily.

 

Only hard starters if you don't replace the glow plugs and relay and your starter isn't up to the job... Or your HPOP is worn to where you can't get the oil pressure you need to fire the injectors... Or your fuel pressure isn't up to par... Or your injector O-rings are failing...

See where I'm going with this?

 

Yep, I think I do. Thanks for the input

 

Because Cold has an o in it like obs but not an n like nbs

 

hahahaha wow. That was rather insightful of you
