Need help with cold start, just switched to Synthetic

Up in Canada land here we are getting into some colder weather. This is my first winter with the truck and it seems to have, what I'm assuming, is some stiction. Mainly coming from one injector.

Prior to this weekend, it was running regular dino oil, castrol 15w40 I believe. No conditioners in the fuel, etc.

When starting, one cylinder would not fire for the first 5 to 10 seconds when cold, but then would pick up. I can hear a distinctive tick noise when running, which I'm assuming is some stiction noise?

Well anyhoo, this weekend I did a new set of fuel filters, oil filter, Rotella T6 5w40, and an accessory belt. When I first started it up (it was in a warm shop) it fired up first time every time, and ran noticeably smoother and quieter.

I drove it home, double checked my oil level, no leaks, all was good.

This morning, it was -11 Celsius (12 Fahrenheit), and when I went to start it, it would fire then die. It did that 3 times, just fire up, but die out right away.
On the 4th time, I gave it a bit of throttle and it stayed running, but ran like a bag of POOP. At least 2 cylinders were not participating for the first 10 seconds, then it smoother out to just 1 cylinder, then it finally picked up for a total of about 15 to 20 seconds.

Over the weekend, I put in a full tank added in some CRC fuel anti gel (see link here, and a 16 oz bottle of 2 stroke oil.

Is there anything I should be starting with? There was no check engine light.

I do have an archoil kit here, that I plan to add in, I was just hoping to do it all in stages so I could post up some better findings rather than switching it all at once.

Thanks folks.

could be air in the fuel system.. Did you take the top fuel filter cap off and then prime the fuel system with the cap off filling the reservoir?

No sir.

I did a search on here, and found a process for replacing them. The only info it gave on the matter was to let the pump run at least 2 times before starting.
Which I did, and it fired up nicely.

Where do I find the procedure for priming? Or what do I do at this point?

It is possible that the lower filter was not seated correctly, there is an air bleed valve in the upper filter, no need to prime the system other than two koeo cycles. Check the lower filter again.

Sent from my phone that somebody didn't help me get.

Will do. Not looking forward to getting soaked in diesel fuel again, but will do!

nothing special on a prime like mentioned

I know the book states 2 cycles but actually u need to cycle more in my experience

the fuel pump only runs for a few seconds at KOEO and watching a fuel gauge I find more like 5 cycles will bring psi to the full

I can't find a distributor for diesel Kleen up here in Canada land, aside from ordering it. Can I use diesel kleen with the archoil?

I always leave the top filter cap off and watch the fuel bowl fill up with fuel- no air bubbles and then i put the cap back on.. No issues with running... Yes like southend said, the lower could not be seated as well... Did u lube the cap o-rings up with motor oil etc?

I assumed you were using Archoil 9000 oil additive?


the diesel kleen is in the fuel and helps with cold temp issues
