Yeah, this is what it says for mine without the push button:

1. Turn the key to position II.
Note: Wait until the glow plug indicator turns off.

2. Fully press the brake pedal.
Note: Do not touch the accelerator pedal.

3. Turn the key to position III.
Note: The engine may continue cranking for up to 15 seconds or until it starts.

Note: The engine takes longer to start at lower temperatures. It may crank for several seconds when very cold.

I'll admit, I haven't taken the time to look for the glow plug indicator, but I'm about to go out and look right now. I thought I had read that waiting for the glow plug was something that older diesels had to wait on though... maybe I'm wrong... I'm going check right now... be right back!

I'm back.... and nope, no indicator came on for a glow plug on my truck...

 

Found it.

As for the glow plug light, I never notice it but don't live in a cold climate. The truck won't start anyway until it's ready to.

 

I bet it's been too warm where I am too for it to come on...

I bet this is the video too:

 

It’s enough of an issue that Ram stopped using them after just 1.5 years. Ram went CP4.2 in 2019, then switched to a different style of CP4.2 more closely related to the CP3 in late 2020.

 

I've read that the CP4.2 that Ford uses has had small changes over the years to improve it's durability. 2015+ apparently had some coating on the pistons. I have seen mention of additional changes being made in 17 and again 2020+ but haven't seen any details on those changes. It would be interesting to know what exactly those differences are and if they have helped lower the number of failures. I'm actually surprised there isn't a write up with photos, or video comparing the HPFP used by Ford, detailing the differences throughout the years, from '11 till now.

 

I'm learning more and more about the modern diesel. I've never owned one but just ordered one. The above video was interesting and I'm surprised the ECM doesn't just do some the items automatically, like wait to start until the glow plugs do their thing. I can imagine most just push the brake and then push start.

 

So I wonder if the truck goes through these steps when we use the key fob to auto start the truck?

 

Most would be correct based on how the manual describes starting it. If need be, such as in very cold weather, there may be a message and delay in starting. Bellow is a partial screen shot for the push button diesel starting procedure.

 

Tow piglet from youtube had a 2020 6.7 cp4 grenade about 40 miles from my house.

 

To avoid the question of/if the trucks cou is properly managing the startup sequence in terms of is the fuel system under pressure before the engine starts cranking…..avoiding dry starts, I installed a 10 psi lift pump . The pump is a key on pump and puts the fuel system under pressure ensuring in my mind that it’s not dry starting.

the lift pump is an additional water removal point and removes air as well as provide additional filtration.

 

So you now have 2 lift pumps? The stock lift pump is key on also, what is wrong with the OEM lift pump?

 

no air removal
poor water separation
and I wanted a second inline pump in the event my intank pump fails. the second pump will prevent dry outs of the fuel that lubes the cp4 roller bearing.
also, the intank pump stops after a few seconds.....so if you press the button and wait...the little pressure it did build up bleeds off thru the fuel sys return lines. once it bleeds off...the pump does not restart...so if you engage the engine start process..CP4 will be running dry.

 

You only hear about the failures because people will complain and come on a forum the second something bad happens. It's not like people out there are looking for a forum just to post they don't have an issue...

For every 1 failure, there's tens of thousands of trucks out there without one.

I still religiously change my filters, get good fuel, and run an additive. But I'm not worrying abiut it...

 

My previous truck had metal particles in the engine bay fuel filter.

I suspect it was a post fuel system failure trade in.

the problem is common enough that fords sells a repair kit for it.
