intermittent miss and hard start

[SPEEDDEMON31176]

Starter. Replace it with the two bolt version from an 02 superduty. It's like a high torque upgrade for the obs trucks. Cranks much faster.

Thanks for the tip wouldn't have known! Here is what my ipr harness looked like

Thats about what my IPR pigtail looked like when I deleted the fuel bowl.

When I lost the heating element in the fuel bowl it did that too... I drove the truck for 6 months with the wires like that. When I did my fuel bowl I figured they couldn't be working so I cut them... Well I learned why the ipr is needed in the HUEI system lol... Seems to be more common then not

I don't know why its such a common problem mine were all melted together. Maybe they didn't use heavy enough gauge of wire? Mine being that way made mine run crappy intermittently for a while it would throw icp codes as well. But once it was fixed no more problems.

Oil and fuel will break down plastic over time.

Add some heat, you get what you saw there.

vibration also causes them to fail at the connectorbecause it causes the contacts inside it to spread , on the newer international engines the ipr valve has about a 6 inch long pigtail on it and the connection is in the wiring harness itself

that's interesting and im still puzzled about my trucks starting because the past two days its been about 17 degrees in the morning when I start it and it turns over super fast and starts quick but I have had some trouble with it starting slow after I have drove it around.

Turning over slow when the engine is hot is usually the first sign the starter is on it's way out.

I'm telling you from experience, mine turned over super slow in the winter, I thought it was just how it was. I also had issues only when cold of the starter hanging up on crank and not shutting off even when the key was out of the ignition. After months of headaches I finally bought the new starter, and all my issues went away. Mine will start in 25 degree weather not plugged in on the first try now.
Before it would slow crank the batteries dead! same batteries until 2 weeks ago, changed the starter last winter

 

[95-F-2FITTY]

Well this sounds weird but its starting better and faster in colder weather than warmer.

 

[Chvyrkr]

It's not weird. Electric motors (like starters) that are going out won't work as well when they get hot.

So, if it's cold outside, engine heat won't saturate the starter so much.

Replace the starter.

Alright alright!LOL I will take yalls advice!
