Rough Cold Start, IPR?

just picked up a 97 CCLB 4x4 E40D last weekend and noticed it has a bit of a rough start different then what i have dealt with on past OBS

no matter if its hot or cold outside( we have had both -5C and +25C in the last week here in Calgary haha)

If its been sitting for more than 12 or so hours without running it doesn't like to start on first crank, it fires a bit and kind of sputters out and dies and then immediately fires on the second crank and runs like a top, doesnt miss a beat at all, if i shut it off and fire it up even a couple hours later it fires up fine, just not when its sitting.

i am thinking maybe sticky IPR? the glow plugs and harnesses/gaskets were done about 3 years ago and injectors/injector o rings done about 4 years ago

when it does fire I do get a little bit of white smoke, nothing crazy but it hasn't been real cold yet either.

I also notice that after I do get it running(the second time) my TS6POS doesn't work, I need to shut the truck off and start it again and then its fine, it doesn't seem to like the rough starts.

Before I pull the IPR to clean it is there any checks I can do with my Auto Enginuity to see if its the IPR?

Thanks
Dustin

Also forgot to mention i notice the WTS light only stays lit for about 3 seconds, no matter how cold or hot the truck is.

I am going to try and throw a Snowplow relay on later today, that woke my last truck up.

Thanks
Dustin

IPR O rings usually cause a hard start when the engine is hot. The WTS light is about right unless its really cold out. A little white smoke is probably because you had to crank on it and its unburned fuel. I don't know what to tell you about the TS?

I would try pulling the TS chip and see if you still have the hard start issue without the chip.

If it isn't under warranty, I'll fix it myself.

What Nate said. That seems to have happened to a few guys on here IIRC.
