I would try to find someone with an AE close or bite the bullet and get it to a ford scanner

 

I replaced the IPR pigtail, and still having problems, so today I pulled the other valve cover(what a bear) and I am replacing another glowplug.
I think I am going to replace the whole IPR harness, the IPR wires are really soft, but they do have continuity. When I took off the harness I unplugged two connectors from the fuel bowl and fPR, but there was another loose one, with a farily big connector and only one big pin. what is it for?

 

Does that help you out?

 

Yeah, that helps, but there is one more single plug. I know the water in fuel sensor and the heater are part of this harness, plus the 2 wires for the IPR. What is the other wire for?

 

Is it the fuel filter restriction sensor wire?

 

Would that throw off a CEL and make the truck run bad when the CEL is on, if the wire was loose or bad or the sensor bad?
Can I just get rid of it along with the Heater?

 

I agree with Darin, and till I know no CEL. Surely PO put a plug in the place of the fuel restriction sensor and left loose the wire as I did. and no more leaks there.

 

Looks like PO did remove the fuel filter restrictor sensor. I don't see a plug in the hole, but obviously something is in there. I'll have to take a better look.

 

Since the fuel restrictor sensor is gone, and you don't really need the fuel heater, can I also get rid of the water detector. That way, I can make a two pin harness just for the IPR.

 

Ya, you can get rid of it, just remember to drain the water from the fuel bowl, that's all it does is warn you to do that.

 

Thanks, that will save me from buying a new $100 harness for all that stuff.

 

I was messing with my IPR harness and now don't know which pin of the IPR should be 12 volts. I can't find the information anywhere. Sometimes I am a dunce.

 

Okay, so if you are looking directly into the IPR receptable where the pigtail goes which pin does the red wire (12 volt) hook to?

 

All I have to do is hook up my IPR and I can fire up the truck, but I don't want it hooked up backwards. I know someone can tell me what pin the red wire goes to in the IPR receptacle.

 

I'm not close to my truck or I'd look for ya. Bump you up top if nothing else..
