Hard start (cold or hot)

This has been happening more often latley. Cold of fully warmed up the truck takes several seconds to start. Sometimes its starts in a second like normal, other times it will just keep cranking. It always starts but it may take 2 or more cycles of the key to get it going.

Is there some common things I could look at? Its been getting worse over the years.

2005 6.0 with 167k miles

Thanks

Look at this video
If you don't have a monitor check the voltage like they do in the video, but if you do have a monitor set the FICM voltage as PID and check the voltage when the key is on but engine off, while cranking, and when the truck is running. The FICM voltage should never go below 46 volts. If it does you FICM is dying and you should probably have it replaced with a Bulletproofdiesel one or have your current one repaired by ed at FICMrepair.com

Most likely have a small leak within the oil system , I would check stand pipes, stc fitting & dummy plugs especially if you have almost 200k on it.

Damn. I don't understand this diesel talk. I don't know what any of the things you mentioned are. The truck has almost 170k on it.

Sorry there pipes inside the engine that oil travels through, they have seals/o rings and they can leak and it can cause a long crank if that makes more sense.

Thanks. That makes sense. Is there a port that you can test the system?
