Recently the CEL has been coming on after the truck starts and runs for about 5 seconds. It runs fine until the light comes on. Truck has no power, gets terrible mileage and runs like it is out of time.

The IPR has been cleaned with the last year. I swapped the CPS as well as the ICP. This did not cure it. The truck runs the same when the connection is pulled off of the ICP and with any one of the UVC plugs pulled.

I am having some software issues with the Auto Engenuity Scan tool. I cant pull codes or run any live stream data on it yet. Hopefully , this will be ready soon.

Any thoughts or suggestions would be greatly appreciated!

 

Sounds like bad uvch

 

What Mike said especially if its intermittent.

 

Is this what I am looking for?
More Information for DORMAN 904201

Also, the specs say it controls 4 injectors and I was thinking they only control 2?

 

Yes but get motorcraft ones. Some have good luck with Dorman, some don't. You get two of what is in your link and it fires 4 injectors. Riffraff Diesel Performance

 

Could be any number of very expensive things. Get AE working FIRST, otherwise you could be throwing a lot of money at this.

 

I'm having difficulty getting autoenginuity to connect to the truck. I finally got to pull codes off of it. The scanner seems as though it will not communicate with the truck even though it says it's connected and initiated. Eventually I did get it to give me a set of trouble codes. However Kama it will not respond when I try to get live data.

 

 

If you have a chip remove it completely off the pcm.

 

What does it look like the codes are pointing to?

Also, I hooked up my mechanical gauge to the oil port on the head. I have a video somewhere, but for the most part it jumped to about 3500 at start up , but then dropped back to below 3000 as if the IPR is working.

Any suggestions?

 

I would clear the codes, and run the truck to see which codes come back, the last two point to the IPR to me. What CPS was used, a parts house one or a Motorcraft one? Motorcraft or IH are recommended as parts house ones don't play well with these trucks.

 

It was an old IH I had laying around to test with.

 

 

AE will not register any psi for the hpop. It says 724 psi and will not change on the live data when the engine RPM increases. However, the mechanical guage to the head will fluctuate.

 

All 8 passed the buzz test.
